PXIe-5665 Calibration Procedure
22. Compare the
Gain Compression
to the verification test limits in Table 45 or Table 46 as
appropriate.
23. Disable the output of RF source 1 and RF source 2.
Note
When disabled, the RF source 1 and RF source 2 output signals should be less
than -60 dBm.
24. Close the PXIe-5665 session.
If the gain compression for frequencies
≤
700 MHz
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.

The device specification calls for less than or equal to 1 dB gain compression for a minimum
applied power. The applied power includes the measurement uncertainty to guarantee the
required minimum applied power.
