PXIe-5665 Calibration Procedure
3.
Set the RF source 1 and RF source 2 frequency and power values according to the first row
in Table 6.
4.
Disable the RF source 1 output, and enable the RF source 2 output.
Note
When disabled, the RF source 1 output signal should be less than -60 dBm.
5.
Measure the channel B power using the appropriate sensor calibration factor for the
RF source 2 frequency.
6.
Repeat step 5, adjusting the RF source 2 power until the channel B reading is within
±0.1 dB of the power listed in Table 6. The RF source 2 power is the
RF Source 2 Programmed Power
.
7.
Disable the RF source 2 output, and enable the RF source 1 output.
Note
When disabled, the RF source 2 output signal should be less than -60 dBm.
8.
Measure the channel B power using the appropriate sensor calibration factor for the
RF source 1 frequency.
9.
Repeat step 8, adjusting the RF source 1 power until the channel B power is within ±0.1 dB
of the power listed in Table 6. The RF source 1 power is the
RF Source 1
Programmed Power
.
10. Repeat steps 3 to 9 for all remaining frequency and power values in Table 6.
