Performance Verification Tests
40. Fast Time Domain Amplitude Accuracy: Agilent E4401B, E4402B, E4404B, E4405B,
and E4407B (Option AYX)
40. Fast Time Domain Amplitude Accuracy:
Agilent E4401B, E4402B, E4404B, E4405B,
and E4407B (Option AYX)
The analyzer amplitude reference signal is used to compare the
amplitude level of a normal sweep time (≥5 ms) to a fast sweep time
(≤5 ms) using the marker functions. The difference should be less than
the marker readout resolution specification for the fast sweep times.
Equipment Required
Cable, BNC, 122 cm (48 in)
Adapter, Type-N (m) to BNC (f)
Procedure
