The following table lists the test equipment required for calibrating NI 9219 modules.
≤5 mVpk-pk 0.1 Hz–10 Hz at 48 V
≤500 µVpk-pk 0.1 Hz–10 Hz at 12 V
≤500 µVpk-pk 0.1 Hz–10 Hz at 3.2 V
≤50 µVpk-pk 0.1 Hz–10 Hz at 0.8 V
≤5 µVpk-pk 0.1 Hz–10 Hz at 0.1 V
The following table lists additional equipment that is required for the calibration fixture.
|Switch Matrix||PXI/PXIe-2737||Switch required for this fixture.|
|X Series MIO Device||PXIe-6341||8 Digital I/O lines capable of driving 24 mA of current each.|
|CAL-9219||P/N 785860-01||NI 9219 Calibration Fixture|
|9219 Calibration Cable Kit|
|160-pin DIN to 160-pin DIN|
|Shielded Cable||SHC68-68-EPM (P/N 192061-01)||68-position D-type to 68-position VHDCI Offset, 1 m cable|
|Banana Cables (x10)||—||—|
Prior to version 4.5, Calibration Executive supported a legacy switch fixture. The new switch fixture is recommended; however, if you use the legacy switch fixture, the following equipment is required.
|Switch Matrix||PXI/PXIe-2529 (x2) and PXI-2503||Switches required for this fixture.|
|Switch Fixture||Custom Switch Fixture||Contact NI and reference NI P/N 539725A-025.|

The following setup and environmental conditions are required to ensure the NI 9219 meets published specifications.
Complete the following steps before running the Calibration Executive procedure.
Although NI recommends that you upgrade to the CAL-9219 fixture and PXIe-2737 switches, Calibration Executive still supports the legacy switch fixture. Complete the following steps to set up the legacy fixture.
To ensure proper operation of the switches used in this procedure, you must periodically test the performance of your switches.
If you use the recommended fixture with the NI 2737 switch matrix, you can use the NI Switch Health Center periodically to confirm that the switch is continuing to operate as expected. The NI Switch Health Center can be found in program files, or you can right-click the NI 2737 switch device in NI-MAX to access the NI Switch Health Center.
If you use the legacy fixture with the NI 2737 switch matrix with the NI 2529 and PXI-2503 switches, refer to the NI 2503/2529 Switch Performance Test for instructions on validating the performance of the switches used in this procedure.
|Note If the fixture used to connect the switches for the NI 9219 procedure is determined to be the cause of performance issues with this procedure, contact NI for support.|
The test limits in this procedure are derived from the published specifications found in the NI 9219 Calibration Procedure.
