Precautions Removing Unwanted Components from Signal The presence of undesired components picked up while the signal passes from the device to the 4352B can result in reduced accuracy in measurement. When connecting a device to the 4352B, take one of the following measures to eliminate these components: The 4352B employs the peak detection method to measure RF power. Therefore, the presence of higher harmonics in the signal makes it extremely di cult to correctly measure RF power.

1 Overview of GPIB Remote Control System This chapter provides information on how to con gure the GPIB remote-control system and the basic use of the GPIB commands. In most of the sample programs shown in this manual, simple GPIB commands are used. For detailed information about each command, see chapters 9 to 11. What is GPIB? The General Purpose Interface Bus (GPIB) is used for remote control of the 4352B VCO/PLL Signal Analyzer.
PAGE 28
To Prepare for GPIB Control 1. Connect the 4352B and controller, plus any other instruments and peripherals with GPIB cables. Figure 1-1. System Con guration for GPIB Remote Control * To set printer or plotter see Chapter 5. 2. Turn on the 4352B. 3. Prepare the system controller. If you are using only HP instrument BASIC and no external controller, press 4Local5 SYSTEM CONTROLLER . For details, see Using HP instrument BASIC with the 4352B.
PAGE 29
How large a system can you con gure? A maximum of 15 devices can be connected on one bus system. The length of cable between one device and another must be less than or equal to four meters. The total length of cable in one bus system must be less than or equal to two meters times the number of devices connected on the bus (the GPIB controller counts as one device). The total length of cable must not exceed 20 meters . Star, linear, and combinational cable con gurations are allowed.
PAGE 30
GPIB Commands Introduction Most of the 4352B's front-panel keys have a corresponding GPIB command. By executing an GPIB command, you can operate the 4352B as if you were pressing the corresponding key. For example, Pressing 4Preset5 is the same as executing the GPIB command, PRES. To Execute an GPIB Command Type the BASIC OUTPUT statement, the GPIB select code, the device address, and nally the 4352B's GPIB command.
PAGE 31
To Program a Basic Measurement This section describes how to organize the commands into a measurement sequence. Figure 1-2 shows a typical program ow for a measurement. Figure 1-2. Program Flow The following program performs the measurement ow controlling the 4352B using GPIB. This manual shows program lists of sample programs for HP instrument BASIC.

PAGE 34
To Execute an GPIB Command with a Parameter Some GPIB commands require a numeric parameter. For example: OUTPUT @Hp4352;"VPOW 4.0" Set DC power voltage to 4 [V]. (The space between the command and the numeric parameter is mandatory.) In lines 200 to 240, you enter the parameters and execute the GPIB commands every time you run the program.

2 Triggering 4352B This chapter describes how to control the trigger system of the 4352B. Note Frequency Transient Measurements can be also triggered using the value trigger function available with the 4352B. See Value Trigger Function in Chapter 12 for details.
PAGE 36
Figure 2-1. Trigger System In Figure 2-1, 1. After a HOLD GPIB command execution, the 4352B returns to the \Idle" state. 2. By selecting the trigger mode with a SING or CONT GPIB command, the 4352B changes from the \Idle" state to the \Waiting for Trigger" state. 3. At the \Waiting for Trigger" state, a trigger input (corresponding to the trigger source) starts a measurement. GPIB *TRG command triggers measurements. Free Run (Internal) There is no need for a trigger input.

3 Synchronizing the Controller with 4352B You can control the 4352B from an external controller to read measurement data and communicate with a handler via GPIB. To do this, it is necessary to synchronize the controller and the 4352B. For example, The program on the controller must wait until after the measurement ends to transfer measurement data. Also, when it controls the handler via the 4352B, it must wait until the communication with the handler is completed before performing the next measurement.

4 Loading Measurement Data into Controller This chapter describes how to load measurement data into an external controller through GPIB.
PAGE 50
Data Formats There are four di erent types of data formats for transferring data from the 4352B via GPIB. FORM2 IEEE 32 bit oating point format FORM3 IEEE 64 bit oating point format FORM4 ASCII format R FORM5 MS-DOS personal computer format The data transfer speed and the number of digits are dependent on the format. Generally, binary data transfer (FORM2, FORM3, or FORM5) is faster than ASCII (FORM4) data transfer. For details on the data transfer formats, see Appendix C.

6 Remote Controlling HP instrument BASIC This chapter describes how to use both HP instrument BASIC and an external controller together, and also how to pass the active controller capability (with an example using a printer). To Control GPIB from HP instrument BASIC The 4352B must be the active controller of the GPIB (select code 7) to control devices on the GPIB, such as an external signal source. Initially, the system controller is the active controller.
PAGE 72
What is the active The active controller is the controller that currently has the capability to control the devices connected via GPIB. Only one active controller can controller? exist at a time on an GPIB bus. If there are two or more devices that can be a controller on the same bus, the active controller capability can be passed from one controller to another.
PAGE 73
Note Only the system controller can assert the GPIB interface clear line (IFC) and remote enable line (REN). Even when HP instrument BASIC is the active controller, these commands cannot be used.
PAGE 74
To Execute an HP instrument BASIC Command From the External Controller. Note d d d The PROGram subsystem commands in the following programs can be used on the external controller. Combine the PROG:EXEC command with a command to be executed on HP instrument BASIC. For example, to execute EDIT command, OUTPUT 717;"PROG:EXEC ""EDIT""" Or you can use single quotation marks, instead of the double quotation marks, as follows.

7 If You Have a Problem This chapter provides helpful information on how to x typical problems. If There Is No Response From an Instrument on the GPIB Bus Check all GPIB addresses and cable connections. This trouble is usually caused by an incorrect address or a bad or loose GPIB cable in most cases. If an Error Message is Displayed Check the error message on the 4352B's display. If \GPIB error occurred" is displayed: 1. Get the error number and description using the OUTPERRO? command.
PAGE 80
If You Cannot Get a File from the Disk Check the oppy disk. 1. Put the disk into the disk drive and type as follows. d CAT a 2. Press 4Return5. If an error message is displayed, the disk is corrupted or the disk format does not match. Use another disk. If you are using the external controller, HP BASIC supports the LIF format only, on the other hand, HP instrument BASIC supports both the LIF and the DOS format.

8 The Status Report System Figure 8-1 shows the overall structure of the Status Report System of the 4352B. Figure 8-1.
PAGE 84
The 4352B has a status report system that reports the status of the 4352B. The Status Byte Register (STB) is an 8 bit register that reports a summary of all the status registers that indicate the current status of the 4352B. Each bit of the status byte reports the status of a speci c event in the 4352B. To read the status byte from the external controller, you can use the SPOLL command. This command can directly read the value of the status byte without setting the 4352B to the remote mode.

Reading the Status Byte: Example (2) The Event Status Register (ESR), Event Status Register B (ESB), and Operational Status Register (OSR) monitor the status of a speci c event, and report to the status byte respectively. A status bit of each register is set to 1 when the corresponding event occurs.

Controlling the 4352B from the External Controller These sample programs are used to measure the device's frequency and C/N ratio in the tester mode with a combination of the 4352B and an external controller. In this case, the external controller controls the 4352B to set up the measurement conditions, make the measurements, and get the measurement results. These operations are performed by passing control from the external controller to the 4352B.

Line 340 passes the controller capability to the 4352B.
PAGE 197
The measurement result is obtained by querying the 4352B (lines 370 to 400). 4352B's Side The 4352B's IBASIC program is continued by the external controller, and makes a measurement (line 200). When the measurement is completed, the controller capability is passed back to the external controller (line 210) and the IBASIC program pauses (line 190).

Controlling the Handler via the 24-bit I/O interface (When the 4352B's External Signal Source Automatic Control Function is Used) These programs control the 4352B and the handler using the external controller. The handshake between the 4352B and the handler is accomplished via the 24-bit I/O port on the rear panel of the 4352B. One of these sample programs shows how to control 24-bit I/O port with GPIB commands or HP instrument BASIC commands.
PAGE 205
The Overview of the Program Figure 12-10. Controlling the Handler with both the IBASIC program and the External Controller Figure 12-10 shows the ow chart for the sample programs. Once the 4352B receives the controller capability, it handshakes with the external controller via GPIB and with the handler via the 24-bit I/O port. The READIO and WRITEIO commands are used to synchronize with the handler, which eventually improves the total processing speed.
PAGE 206
4352B's Side The IBASIC program is started by the external controller, and then assigns the I/O path of the external controller so that data with a tab code is transferred to the controller (line 140). This assignment makes it easier to handle measurement results from spreadsheet software. Then, the 4352B is set up (line 160) and the following processes are performed in the measurement loop (lines 170 to 280). The 4352B makes a measurement when a trigger is sent from the handler to INPUT1 (line 180).

Synchronizing with the Handler Figure 12-13. Synchronizing with the Handler via the 24-bit I/O port This program controls the 4352B and the handler to measure the DUTs per lot. In this case, the 4352B and the handler must be synchronized to perform the following handshakes. a. The 4352B noti es the handler that a new DUT is ready for measurement. b. The handler noti es the 4352B that the DUT has been connected to the electrodes of the xture on the handler. c.

Application in the Analyzer Mode (Frequency Transient Measurement) This program measures the PLL frequency transient characteristics. In this section, four programs are provided, each of which uses a di erent trigger. Note The 4352B o ers you three ways to measure the PLL oscillation frequency characteristics with respect to time. Select the method that best suits your needs. Observation time Method Reference 10 sec or shorter Frequency transient measurement Program given in this section.

Sending Trigger in Frequency Transient Measurement The purpose of a frequency transient measurement is to evaluate how quick the PLL output frequency changes in response to a request for frequency change. To ensure accuracy in this measurement, the following operations must be performed in as short a time as possible.
PAGE 230
You can select in advance whether to use when f exceeds fT or when f decreases below fT as the trigger condition. When you switch f from fL over to fH (fL < fH ), be sure to set fT at a level slightly higher than that of fL . This allows a measurement to be initiated immediately after a frequency change request has been sent to the PLL.

Lines 700 to 720: Specify Measurement Time This block speci es the default measurement time. However, line 2200, provided later in the program, allows you to type in a desired measurement time. Therefore, you do not always need to specify it in this block. Measurement time is set at 10 msec in this block. Lines 800 to 850: Specify DC Power Voltage This block speci es the 4352B's DC power voltage. The DC Power voltage is set at 5 V in this program. You may need to change it in accordance with your DUT.

Therefore, it corresponds to CASE ELSE in line 1530. Consequently, TSMAX is selected and the frequency span is set at 512 MHz ( xed). Because line 1580 speci es 50% for target position, minimum and maximum frequencies are calculated as follows: Minimum frequency: 5.

You need to use it if the PLL outputs a signal beyond 3 GHz. In this case, you must treat line 920 as an executable statement while at the same time commenting out line 930.

In line 1570, the 4352B is set at 180.8 MHz (frequency speci ed in line 460) as target frequency (TRTARG). Lines 1700 to 1740: Turn ON Trigger Detection Output Function This block selects internal trigger (TRGS INT) and turns ON the trigger detection output function (TRGOUT ON). OUT1ENVH is used to pull OUTPUT1 (24-bit I/O) high. OUTPUT1 is connected to the PLL Load terminal. (See Figure 12-22.) The PLL loads serial data available at the DATA terminal when the LOAD terminal goes high.

Using the Value Trigger Function - 1 (43521A and Serial Data) Figure 12-28 shows a frequency transient measurement program using the value trigger function. In this program, the same PLL as that for \Using the Trigger Detection Output Function - 1 (43521A and Serial Data)" is used. See the above-mentioned section for information on the PLL block diagram and its connection. This PLL requires serial data for initialization and frequency division ratio signals.
PAGE 251
This block selects whether to use the 43521A (Down Converter Unit). In this program, a high frequency signal (5.8 GHz) is measured. Therefore, you need to use the 43521A. You do not need to use it if the target frequency is 3 GHz or less. In this case, treat line 930 as an executable statement and comment out line 920. Lines 1000 to 1080: Specify SG Type and SG Local Signal Wait Time This block speci es an SG type number of the external signal source (SG) and local signal wait time.
PAGE 252
In this case, because frequency span is 512 MHz, overshoot is unlikely to exceed the maximum frequency or fall below the minimum frequency. However, if 2 MHz is selected for frequency span due, for example, to a small di erence between maximum and minimum frequencies, overshoot may fall outside the range between maximum and minimum frequencies. In this case, assign any value greater than 1 for Over shoot to provide a wider frequency span.

File Transfer Function This section describes how to use the le transfer function, showing you a sample program. The le transfer function uses the external controller to transfer les between the selected storage device of this instrument (memory disk or diskette) and an external storage device (such as hard disk). This function allows you to: Directly access data you want to use on the external controller.

Lines 510 to 560 check the data length. If the data length is 0, the transfer process is terminated. Depending on the data length obtained in lines 590 to 610, the program adjusts the format and reads the data part. Line 620 writes the data to the destination le. The maximum length of data transferred at a time is 16 Kbytes.

C Data Formats Data Formats There are four di erent types of data formats used to transfer data from the 4352B via GPIB. You must consider the data format not only at data transfer, but also when making the data array declaration of either real or integer because this format determines the type of data to be transferred. Form 2 Form 2 is IEEE 32-bit oating point format. This format expresses a number in four bytes. Figure C-1 shows the data transfer format of Form 2 in the Tester mode. Figure C-1.
PAGE 300
Figure C-3. The Data Transfer Format for Form 3 (Tester mode) When the Analyzer mode is selected, the data trace is transferred in a similar manner to Form 2, except it is transferred in sequences of 8-byte data. For example, the data length for 201 measurement values will be 1,608 bytes. Figure C-4 shows the data transfer format of Form 3 in the Analyzer mode. Figure C-4. The Data Transfer Format for Form 3 (Analyzer mode) Form 4 Form 4 is the ASCII data transfer format.

D I/O Port Function Speci cations The 4352B's rear panel provides two parallel I/O ports, a 24-bit parallel I/O port that enables a 24-bit output or an 8-bit input at maximum, and a 12-bit parallel I/O port that enables 8-bit output and 4-bit input. These I/O ports enable the handshake between the 4352B and an external controller such as a PC or an external device such as handlers used in production line testing. To control these I/O ports, you must use either GPIB commands or some special IBASIC commands.
PAGE 302
24-bit I/O port The 24-bit I/O Port The 4352B's 24-bit I/O port has four independent parallel ports for data input or output, and several control signal and power lines. All signals are TTL level. The data I/O port consists of 2 pairs of 8-bit output ports and 2 pairs of 4-bit two-ways ports. If you use these ports together, you can use them as a 24-bit output port or as an 8-bit input port at maximum.
PAGE 303
24-bit I/O port WRITE STROBE Output Signal When data is output to any output port, a negative pulse is output to the WRITE STROBE output. This negative output pulse noti es an external device of data output to the parallel I/O port. The pulse width is 10 s (typical). Figure D-1 shows the timing chart for the WRITE STROBE output and data output. Figure D-1. Write Strobe Signal Timing Chart INPUT1 Input Signal When a negative pulse is input to INPUT1, OUTPUT1 and OUTPUT2 are set to LOW or HIGH.
PAGE 304
24-bit I/O port +5V Output A +5V output can be provided to an external device. The maximum current supplied is 100 mA. This line does not have a fuse. When excessive current ows, the 4352B's protection circuit automatically shuts down its internal power supply circuits. If you remove the cause of the excessive current, the 4352B's power will be turned on but the 4352B's setups are reset to the default settings.

Data Input The following commands read data sent from an external device to an input port (C to E) and return the value to an HP IBASIC program. If you use the port as an input port, the port must be de ned as an input port using the GPIB commands CIN and/or DIN.
PAGE 310
24-bit I/O port Positive or Negative Logic Setting You can set the logic level of the following ports and signal to negative or positive using the following GPIB command NEGL or POSL. When the power is turned ON, negative logic is set. 4Preset5 does not a ect this setup. This setup is saved to an instrument state le using the Save function. Output ports A to H Input ports C and D PASS/FAIL signal NEGL Sets negative logic. POSL Sets positive logic.
PAGE 311
12-bit I/O port 12-bit I/O port The 4352B's 12-bit I/O port consists of an 8-bit output, a 4-bit input, and three ground terminals. This I/O port also uses TTL level operation. I/O Pins Figure D-4 shows the I/O pins. Figure D-4. The I/O Port Pin The signals assigned to each pin are described below: OUT 0 through 7 Signal lines used to output signals to an external device. They are controlled by the command, WRITEIO or OUT8IO as described below.
PAGE 312
12-bit I/O port GPIB Commands for the 12-bit I/O Port Control The GPIB commands related to the parallel I/O ports are described below: OUT8IO Outputs 8-bit data through lines OUT 0 to OUT 7. The OUT 0 signal is the LSB (least signi cant bit), and the OUT 7 signal is the MSB (most signi cant bit). INP8IO? Inputs 4-bit data through lines from IN 0 to IN 3 to the 4352B's memory and returns the data to a control device such as an external controller IBASIC program.
