16. Other Input Related Spurious
Responses
A synthesized source and the spectrum analyzer are set to the same
frequency and the amplitude of the source is set to 10 dBm. A
marker-amplitude reference is set on the spectrum analyzer. The source
is then tuned to several different frequencies where image responses
could occur. At each source frequency, the source amplitude is set to
10 dBm and the amplitude of the response, if any, is measured using
the spectrum analyzer marker function. The marker-amplitude
difference is then compared to the specification.
There are no related adjustment procedures for this performance test.

Equipment Required

Synthesized sweeper
Measuring receiver (used as a power meter)
Power sensor, 100 kHz to 1500 MHz
Adapter, Type-N (f) to APC 3.5 (f)
Adapter, Type-N (f) to Type-N (f)
Cable, Type-N, 152-cm (60-in)

Additional Equipment for 75

Power sensor, 75
Adapter, Type-N (f), to BNC (m), 75
Adapter, BNC (m), to BNC (m), 75
Pad, minimum loss

Procedure

1. Zero and calibrate the measuring receiver and 100 kHz to 1500 MHz
power sensor in log mode (power reads out in dBm), as described in
the measuring receiver operation manual. Enter the power sensor's
500 MHz Cal Factor into the measuring receiver.
