Call the ni5110 Ext Cal API.lvlib:DC Reference Cal Adjust VI with the following
settings:
•

actual voltage generated (V)

: the DC voltage present on the specified channel of

the PXIe-5113

Repeat steps 3 through 6 until the

dc reference cal complete

indicator of the ni5110 Ext

Cal API.lvlib:DC Reference Cal Adjust VI returns

TRUE

Disable the calibrator output.

Adjusting 50

DC Reference

Follow this procedure to adjust the DC gain and offset of the 50 Ω DC reference of the
PXIe-5113.
1.

Connect the calibrator test head to the specified channel of the PXIe-5113.

Call the ni5110 Ext Cal API.lvlib:DC Reference Cal Initialize VI with the following
settings:
•

: the specified channel

•

input impedance

: 50 Ω

Call the ni5110 Ext Cal API.lvlib:DC Reference Cal Configure VI to obtain the DC
voltage to generate, and configure the calibrator with the following settings:
•

Output: the specified DC voltage

•

Load impedance: 50 Ω

Enable the calibrator output if it is not already enabled.

Wait 1 second for settling.

Call the ni5110 Ext Cal API.lvlib:DC Reference Cal Adjust VI with the following
settings:

Reverification

Repeat the

Verification

section to determine the as-left status of the PXIe-5113.

Note

If any test fails reverification after performing an adjustment, verify that you

have met the test conditions before returning your PXIe-5113 to NI. Refer to the

Worldwide Support and Services
