Keysight Y1252A Calibration Kit for the
M9195A DSR
Keysight’s Y1252A kit (three cables and this Installation
Guide) is used to fully calibrate the M9195A onboard
ADC.
Use the M9195A Soft Front Panel software or the
KtMDsr API to perform the calibration. The SFP
software is available on the Product and Information
CD supplied with the M9195A. It is also available at
www.keysight.com/find/M9195A.
Keysight requires an external calibration on a one year interval in order to guarantee specifications.
An Auto Corrections, not requiring the Y1252A cable or DMM, is available in the Soft Front Panel (Instrument
tab) and may be done at any time.
Calibration Requirements
Module calibration with an external DMM is used as a transfer standard to the onboard ADC. Adjustment
requires use of Y1252A calibration kit and a DMM with the required accuracy (see table on the next page).
Calibration also requires the module to be in the environment of 23 °C ± 3 °C (RH < 80%) temperature range for
a minimum of 1 hour and requires a 30 minute warm-up period. Warm-up period is defined as the module
operating in a powered PXI chassis along with having initialized the hardware with the software IVI driver.
Initialization can be accomplished by either opening the SFP or calling the IVI driver in a custom application.
Follow instructions in the M9195A Startup Guide to ensure proper software driver and hardware installation. The
Y1252A User Guide should be followed to make the appropriate connections.
Full module verification can’t be performed with Y1252A Calibration Kit. This is because
verification is done on a channel-by-channel basis.
Module ADC calibration is accomplished by reading a series of DC voltages, in each ADC range, along with two
calibration currents. Measurements should be made with a DMM capable of meeting or exceeding the accuracy
specified in the table on the next page. Executing the adjustment routine can be performed from the SFP or
programmatically through the IVI driver. Module calibration averaging mode must be set to normal mode
rejection, which will be Window50Hz or Window60Hz depending on the site electrical system.

After the external adjustment is complete, the Automatic Corrections routine will run. Automatic Corrections
should take several minutes to complete and should run without error. Once all calibration tasks are
completed, the module can be verified (optional).
Refer to the M9195A Service Guide for module verification procedures.
Calibration Process for the M9195A
Refer to M9195A Soft Front Panel help file for detailed calibration instructions.
1. Assemble the BNC-to-Banana plug cables to the main Y1252A cable (with module fixture).
2. Attach the Y1252A cable to the M9195A module to be calibrated.
3. Connect the cable Banana plugs to the DMM voltage input and current input terminals. Refer to the
following diagram for connections:
4. Turn on the DMM and power-up the chassis with the M9195A. Allow both to warm up for at least 60
minutes
5. After the warm-up period. Run the M9195A SFP software.
6. From the SFP, select the M9195A to be calibrated.
7. In the SFP, select Utilities > Calibration Wizard….
8. Start the Calibration. Follow all on-screen instructions.
Current measurements must be entered into the SFP in units of Amps, not mA.
After entering all of the voltage and current measurements, you will be instructed to remove the calibration
fixture from the M9195A module before finalizing the calibration.
