This section describes the performance verification test procedure listed on Table 6-1.
6.3.1.1 Noise Level
Description:
Verify the external mixer’s noise level both frequency range of 50 GHz to 75 GHz and 70 GHz to 80
GHz.
Firstly load the correction data on the backed up floppy disk to R3172/R3182 internal memory. Set
the sweeper output to off.
Measure the noise level in ht entire frequency range of each external mixer by 500 MHz step.
