14. Call the niScope Initialize VI to obtain an NI-SCOPE session.
15. Self-calibrate the PXIe-5164 using the niScope Cal Self Calibrate VI.
16. Call the niScope Close VI to close the NI-SCOPE session.

Adjusting 1 M

Ω

Compensation Attenuator

Follow this procedure to adjust the 1 MΩ compensation attenuator of the PXIe-5164.
1.

Connect the calibrator test head to the specified channel of the PXIe-5164.

2.

Call the niHsai Group B External Cal API v1 Host.lvclass:Compensated Attenuator Cal
Initialize VI with the following settings:
•

channel

: The specified channel

•

input impedance

: 1 MΩ

3.

Call the niHsai Group B External Cal API v1 Host.lvclass:Compensated Attenuator Cal
Configure VI to obtain the amplitude and frequency of the square waveform to generate.
Configure the calibrator to output a square waveform with symmetrical polarity and with
the specified amplitude and frequency into 1 MΩ.

4.

Enable the calibrator output if not already enabled.

5.

Wait 1 second for settling.

6.

Call the niHsai Group B External Cal API v1 Host.lvclass:Compensated Attenuator Cal
Adjust VI with the following settings:
•

frequency generated (Hz)

: The frequency of the square waveform present on the

specified channel of the PXIe-5164

•

amplitude generated (Vpk-pk)

: The amplitude of the square waveform present on

the specified channel of the PXIe-5164

7.

Repeat steps 3 through 6 until the

compensated attenuator cal complete

indicator from

the niHsai Group B External Cal API v1 Host.lvclass:Compensated Attenuator Cal
Adjust VI returns TRUE.

8.

Disable the calibrator output.

Return to the main

Adjusting the PXIe-5164

task.

Adjusting 1 M

Ω

DC Reference

Follow this procedure to adjust the DC gain and offset of the 1 MΩ DC reference of the
PXIe-5164.

Caution

Avoid touching the connections when generating a high voltage from the

calibrator.

1.

Connect the calibrator test head to the specified channel of the PXIe-5164.

2.

Call the niHsai Group B External Cal API v1 Host.lvclass:DC Reference Cal Initialize VI
with the following settings:
•

channel

: The specified channel

•

input impedance

: 1 MΩ

3.

Call the niHsai Group B External Cal API v1 Host.lvclass:DC Reference Cal Configure
VI to obtain the DC voltage to generate and configure the calibrator to output the
specified DC voltage into 1 MΩ.
