5-32
5.2.9 Input Attenuator Switching Accuracy (R3172/82)
This test measures input attenuator’s switching accuracy over the full 70 dB.
The number of frequency measured points is three points at 4 GHz, 15 GHz and 18 GHz.
IF Gain uncertainty is measured when the resolution bandwidth is set to 1 kHz and result is filled in on the
IF Gain uncertainty of the performance verification record sheet.
Specification:
Reference to 10 dB input attenuation.
