PXIe-5665 Calibration Procedure
23.
(PXIe-5665 14 GHz VSA)
Repeat steps 6 to 21 for test frequencies between 3.8 GHz and
7 GHz with the PXIe-5665 preselector enabled.
24. Repeat steps 6 to 22 for the frequencies in Table 38 with the PXIe-5665 preamplifier
enabled.
25. Compare the
SHI
to the verification test limits in Table 39, Table 40, or Table 41 as
appropriate.
