PXIe-5665 Calibration Procedure
4.
Set the PXIe-5665 center frequency using the following values:
•
Start frequency: 100 MHz
•
Stop frequency:
–
(PXIe-5665 3.6 GHz VSA)
3.6 GHz
–
(PXIe-5665 14 GHz VSA)
14 GHz
•
Step size: 9.997331 MHz
5.
Commit the PXIe-5665 settings to hardware.
6.
Read the power spectrum from the PXIe-5665.
7.
Measure the highest power in the spectrum returned from the PXIe-5665. This value is the
PXIe-5665 Non-Input-Related Spurious Level
.
8.
Repeat steps 4 to 7 for all frequencies in step 4.
9.
Compare the
PXIe-5665 Non-Input-Related Spurious Level
to the verification test limits in
Table 21.
10. Close the PXIe-5665 session.
If the non-input-related spurs (residual spurs) verification procedure determines that the
PXIe-5665 is outside its limits, refer to
Worldwide Support and Services
for information about
support resources or service requests.
