16. Connect splitter output 2 of the power sensor assembly to channel 1 of the PXIe-5113 and
repeat steps 2 through 14 for each configuration listed in the
table.
17. Disable the signal generator output.
Adjustment
This section describes the steps needed to adjust the PXIe-5113 to meet published
specifications.
Adjusting the PXIe-5113
Before performing this procedure, complete the following:
•
Complete the
procedures;
•
Calculate the splitter loss of your power splitter; and
•
Ensure the channels of the PXIe-5113 are not connected.
Complete the following steps to adjust the PXIe-5113.
1.
Call the ni5110 Ext Cal API.lvlib:Open Ext Cal Session VI to obtain an external
calibration session.
To perform an adjustment, you must specify the
calibration password
. The default
calibration password is
NI
.
2.
Complete the
Adjusting 1 MΩ Compensation Attenuator
procedure on channel 0.
3.
Complete the
4.
Complete the
procedure on channel 0.
5.
Complete the
Adjusting 1 MΩ Compensation Attenuator
procedure on channel 1.
6.
Complete the
7.
Complete the
procedure on channel 1.
8.
Call the ni5110 Ext Cal API.lvlib:Close Ext Cal Session VI with the following settings to
close the external calibration session:
action
: Set this parameter to
Commit
to store the new calibration constants, adjustment
time, adjustment date, and adjustment temperature to the nonvolatile memory of the
oscilloscope. If any errors occurred that were not corrected during any of the external
adjustment steps, or if you want to abort the operation, set this parameter to
Cancel
to
discard the new calibration constants without changing any of the calibration data stored
in the nonvolatile memory of the oscilloscope.
9.
Call the NI-SCOPE Initialize VI to obtain an NI-SCOPE session.
10. Use the Self Calibrate VI to self-calibrate the PXIe-5113.
11. Call the 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-5113.
1.
Connect the calibrator test head to the specified channel of the PXIe-5113.
