Safety Issues Normal use of test equipment presents a certain amount of danger from electrical shock because testing must be performed where exposed voltage is present. An electrical shock causing 10 milliamps of current to pass through the heart will stop most human heartbeats. Voltage as low as 35 VDC or RMS AC should be considered dangerous and hazardous since it can produce a lethal current under certain conditions.
9530 Front Panels Display Layout and Indicators A graphical display module displays parameters and status information. The status information is located in the upper-left corner of the display, between the two brackets. There are three enunciators: Vertical Arrow Blinking Light Indicates there are additional pages to the current menu. Indicates the unit is actively generating pulses, or armed and waiting for an external trigger.

Channel Timer Functions The Channel Timer functions as a non-retriggerable, delayed, one shot pulse generator. This means that the timer will only generate one delayed pulse for every start pulse received. Once the channel timer has started counting, additional start pulses will be ignored until the pulse has been completed (nonretriggerable). The start pulse for each channel is provided by the internal To pulse generated by the Internal System Timer.
Press the Page button to select the next page. There may be multiple channel menus depending upon your unit. Secondary menus can be accessed by pressing the letter key of that channel a second time. There are also individual menu keys for the gate (GATE), trigger (TRIG), and system (MENU) menus. Depending upon your unit, each of these menus may have multiple pages, accessed by the Page button, or secondary menus, accessed by pressing that particular function key a second time.
NOTE: If Wid + Dly + 75ns (hardware reset time) > To Period, the correct pulsewidth will be generated but at a slower rate. Setting Pulse Output Parameters There are two basic types of outputs available on the 9530: (a) TTL/CMOS compatible outputs; (b) adjustable amplitude outputs. Out: Pol: Ampl: Selects between TTL/CMOS mode and Adjustable mode when both are available on a single output. Sets the voltage polarity of the pulse, active high or active low.

Select a configuration number. *NOTE: You cannot store to the zero location, as that contains the factory default values. Label the configuration as desired. From the Store menu, press the store button sequence (Page). *NOTE: When the unit powers up it will recall the last stored or recalled configuration.
Quick Start - Normal Internal Rate Generator Operation The 9530 has a powerful set of functions providing a number of modes of operation for the internal or System rate generator (To). Most of these functions can be ignored if a simple continuous stream of pules is required. Starting from the default settings, which can be recalled by recalling configuration 0, the following parameters need to be set: Pulse Width, Delay Enter the Channel menus by pressing the letter key.
Edge Press the NEXT key until the Edge parameter is highlighted. Set the instrument to trigger off the rising edge or falling edge as desired. Pulse Width, Delay Enter the Channel menus by pressing the letter key. Enter the required pulse width and delay. Repeat for each output channel. Start Press the RUN/STOP key to start/arm the instrument. The 9520 will now generate a pulse for every valid trigger. Stop Press the RUN/STOP key a second time to stop/disarm the instrument (i.e.

Personal Computer to Pulse Generator Communication The 9530 comes standard with an RS232 serial and USB interface. An Ethernet interface is available as an option. All menu settings can be set and retrieved over the computer interface using a simple command language. The command set is structured to be consistent with the Standard Commands for Programmable Instruments. Although due to the high number of special features found in the 9530, many of the commands are not included in the specification.
install the USB drivers, and make that COM port number available for typical RS232 communication to the pulse generator. Hyperterminal or other common software may be used. When communicating through the mapped COM port over USB, the baud rate for the communication port used by the USB chip must match the baud rate for the COM port on the pc. Access to the USB port baud rate is done using the SCPI command :SYSTem:COMMunicate:SERial:USB n command, where n is the desired communication speed.
The Ethernet module used is a Digi Connect ME module supplied by Digi Connectware, Inc. There are several ways to successfully communicate with the pulse generator over Ethernet. The two most popular methods are raw TCP/IP (such as Labview or programming with VISA libraries) and by mapping a pc COM port using the Digi Connectware s Realport Drivers .
The command string is parsed and executed after reading these characters. These characters are the carriage return and linefeed . They are ascii character set values 13 and 10 respectively (hex 0x0D and 0x0A). All command strings need to have these characters appended. When the pulse generator responds to a command, whether it is a query or a parameter change, it also appends its return strings with these characters. Coded applications could use this behavior to know when to stop reading from the unit.
SCPI Command Format SCPI commands control and set instrument specific functions such as setting the pulsewidth, delay and period. SCPI commands have a hierarchical structure compose of functional elements that include a header or keywords separated with a colon, data parameters and terminators. For example: SCPI Format :PULSE1:STATE ON :PULSe1:WIDTh 0.000120 :PULSe:POL NORMal Any parameter may be queried by sending the command with a question mark appended.
After power-up or reset (*RST) The instrument default is channel #1. SCPI Parameter Types The following parameter types are used: Accepts all commonly used decimal representation of numbers including optional signs, decimal points and scientific notation: 123, 123e2, -123, -1.23e2, .123, 1.23e-2, 1.2300E-01. Represents a single binary condition that is either true or false. True is represented by a 1 or ON; false is represented by a 0 or OFF.
Example 2) 25 s pulsewidth, 0 delay, external trigger, one pulse for every trigger. :PULSE1:STATE ON :PULSE1:POL NORM :PULSE:WIDT 0.000025 :PULSE1:DELAY 0 :PULSE0:MODE SING :PULSE:TRIG:MODE TRIG :PULS:EXT:LEV 2.5 :PULS:EXT:EDGE RIS enables channel A sets polarity to active high sets pulsewidth to 25 s sets delay to 0 sets system mode to single shot sets system to external trigger sets trigger level to 2.
