39. Residual Responses

39. Residual Responses

The analyzer input is terminated and the analyzer is swept from
150 kHz to 1 MHz. Then the analyzer is swept in incremental 10 MHz
spans from 1 MHz to the upper frequency range. Any responses above
the specification are noted.
There are no related adjustment procedures for this performance test.
Equipment Required
Termination, 50 Ω Type-N (m)
Additional Equipment for 75 Ω Input
Termination, 75 Ω, BNC (m)
Adapter, Type-N (f) to BNC (m), 75 Ω
Additional Equipment for Option BAB
Adapter, Type-N (f) to APC 3.5 (f)
CAUTION Use only 75 Ω cables, connectors, or adapters on instruments with 75 Ω
input, or damage to the input connector will occur.
Procedure
150 kHz to 1 MHz
1. Connect the 50 Ω termination to the analyzer input as shown in
Figure 2-57.
75 Ω Input: Use the adapter to connect the 75 Ω termination, and
continue with step 4.
