Amplitude Linearity

Test Limits

The linearity error will be ≤ ±1.0 dB with ≤ −10 dBm at the mixer.

Test Description

This test checks the amplitude linearity of the instrument by maintaining a constant
reference level and measuring signals of different amplitudes over most of the display
range. This test sets the input attenuator to 10 dB and the Reference Level to 0 dBm. The
external attenuator is set to 0 dB, and the amplitude of the source is adjusted to set the
displayed signal at the reference level.
The instrument's internal marker is used to measure the reference amplitude. The Marker
Delta function is activated and the RF input is reduced using the external precision step
attenuator. Signal input levels from 0 dBm to −50 dBm are measured.
