2 Calibration Introduction Prior to checking the performace of the instrument, ensure that you have all the equipments listed in the following to perform the verification procedure for analog input and analog output.
Calibration 2 Types Of Signal Sources Ground-referenced signal sources A ground- referenced signal source is defined as a signal source that is connected in some way to the building’s grounding system. This means that the signal source is connected to a common ground point with respect to the U2300A series DAQ (assume the host PC which is connected with DAQ is in the same power ground). Floating signal sources A floating signal source is a signal that is not connected to the building’s grounding system.
2 Calibration Input Configurations Single-ended connections A single- ended connection is applicable when the analog input signal is referenced to a ground and can be shared with other analog input signals. There are two different types of single- ended connections, which are RSE and NRSE configuration.
Calibration 2 • Non- Referenced Single- Ended (NRSE) Mode In NRSE mode, the DAQ device does not provide the grounding point. The ground reference point is provided by the external analog input signal. You can connect the signals in NRSE mode to measure ground- referenced signal sources, which are connected to the same grounding point. The following figure illustrates the connection.
2 Calibration Differential Input Mode The differential input mode provides two inputs that respond to the difference of the signal voltage. The analog input of the U2300A series DAQ has its own reference ground or signal return path. The differential mode can be used for the common- mode noise rejection if the signal source is ground- referenced. The following figure shows the connection of ground- referenced signal sources under differential input mode.
Calibration 2 The following figure illustrates the connection of a floating signal source to the U2300A series DAQ in differential input mode. For floating signal sources, additional resistor is needed at each channel to provide a bias return path. The resistor value is equivalent to about 100 times the source impedance. If the source impedance is less than 100 W, you can connect the negative polarity of the signal directly to AI_GND, as well as the negative input of the Instrumentation Amplifier.
2 Calibration Hardware Connection The connection to verify the analog input readings and analog outputs are different. To verify the analog input readings, see “Analog Input Connection” for descriptions on the way to connect the instruments. To verify the analog outputs, see “Analog Output Connection” for descriptions on hardware setup. Analog Input Connection The equipments required for analog input connection are the DAQ device, Fluke calibrator, terminal block, USB mini- B cable and SCSI cable.

2 Calibration Analog Output Connection The equipments required for analog output connection are the DAQ device, DMM, terminal block, USB mini- B cable and SCSI cable. Follow the follwing step- by- step instruction for analog input connection. 1 Connect the DAQ device to a PC with a USB mini- B cable and connect the DAQ device to a U2901A terminal block using the U2901A SCSI cable. NOTE • Ensure that the PC has the DAQ device’s driver and the Agilent IO Libraries 14.2 or higher installed.
Calibration DAQ DMM AO201 Input AOGND GND 2 Figure 2-7 The analog input and DMM connection Setup diagram Terminal Block DAQ SCSI Cable Mini-B USB Cable PC Analog Output (e.g.
2 Calibration Self-Calibration Self- calibration can be operated using the following SCPI command via Agilent Connection Expert. CALibration:BEGin In calibration mode, the command will initiate a voltage adjustment in sequence for the specified Digital Analog Converter (DAC) channel. This sequence sets a zero and gain adjustment constant for each DAC output. The function of DAQ device will not carry on until the self- calibration has completed.
Calibration 2 3 Connect the DAQ device to the PC with mini- B type USB cable. The connected DAQ device will be visible in the Instrument I/O on this PC panel as illustrated in Figure 2- 5. 4 Select the DAQ device that you wish to send the SCPI commands to and then click the Interactive IO icon on the toolbar to launch the Agilent Interactive IO. See Figure 2- 5.
2 Calibration 6 Successful communication between the Agilent Connection Expert and the connected hardware will be shown in the Instrument Session History panel. The users may now send other SCPI commands to the instrument. Figure 2-10 Interactive IO dialog box 7 Ensure that the DAQ device has been warmed up for 30 minutes. Send the SCPI commands “*RST” and “*CLS” to clear the register in DAQ device. 8 Send “CAL:BEG” to start the self- calibration process. This process may take a few minutes to complete.
Calibration 2 Option 2: Self-calibration with Agilent Measurement Manager WA R N I N G • Unplug all cables that are connected to the DAQ device before performing self-calibration. • Any cables connected to the DAQ device may cause the failure of the self-calibration process. 1 Power on the DAQ device and disconnect all connections from it. Warm it up for 30 minutes to ensure that it is operating at stable condition. 2 Connect the DAQ device to the PC with mini- B type USB cable.
2 Calibration 5 Select the instrument that you would like to perform self- calibration and the Start button will be enabled. Click Start to proceed. See Figure 2- 8. 6 The calibration process will take a few minutes to be completed. Once done, the status and results of the process will be displayed as shown in Figure 2- 9.

2 Calibration Adjustment Procedures DAQ on- board 5 V calibration If in the performance verification procedure is not accurate, adjustment procedure is required. The following flowchart shows the steps for 5 V calibration. Step 1: Open the DAQ device metal casing. Power on DAQ device and warm up for 30 minutes. Connect the DMM to U37 on the daughter board. Step 2: 5 V calibration Connect the DAQ device to the computer with USB cable. Monitor the DMM readings.
Calibration 2 Table 2-3 Step-by-step descriptions for Figure 2-10 Step Descriptions Step 1 Before power on the DAQ device, open the DAQ device’s metal casing. Refer to “Dismantle Procedures” for more information to disassemble the unit. Then, power on the DAQ device and warm it up for approximately 30 minutes. Connect the DMM to U37 on the daughter board. The following images shows the location of U37 and the way to connect it.
2 Calibration Performance Verification Procedure Prior to calibrate the instrument, check the performance of the instrument to see if any adjustment is required, “Step 2: DAQ configuration and verification test”. This is to ensure that the DAQ device gives accurate readings or outputs. The performance verification procedure for analog input and analog output are automated and are verify using the Automated Calibration software.
Calibration 2 Step 1: DAQ self- calibration Step 1: Power on DAQ device and disconnect all connections from DAQ. Warm up for 30 minutes.
2 Calibration Step 2: DAQ configuration and verification test Step 1: Power on DAQ device and connect the calibrator to DAQ. Warm up for 30 minutes.

Warm up for 30 minutes Step 2: DAQ configuration Send “SOUR:VOLT:POL Polarity,(@Channel)”, Send “SOUR:VOLT”RSRC INT,(@Channel)”, Send “SOUR:VOLT Voltage,(@Channel)” Step 3: DMM Measure the output voltage of DAQ Repeat steps above for all channels and polarities.
2 Calibration A/D Data Conversion A/D data conversion converts analog voltage into digital information. The following section illustrates the format of acquired raw data for the A/D conversion. Below is the illustrated example of the acquired raw data scan list for CH 101, CH 102, and CH 103. #800000200 Data length indicator, The next 8 bytes (0000 0200) specifying the actual data length only, not actual data.
