(FRA) Screen Display Areas
The main area shows “frequency”, “gain”, “phase” and
“delay” measurements as follows:
“
Frequency”:
This is the frequency the generator has
been set to.
“
Gain”:
Shows the measured amplification/attenuation
between the input and output.
“
Phase”:
This is the relationship seen between the input
and output phases.
“
Delay”:
This determines the
time between the input and
output phases
and considers this measurement to be the
delay time.
“
Level”:
The “bottom left” level displays the input rms
voltage being fed into the system under test.
Note: The output level of the generator when connected to
one of the inputs may differ to the measurement reading
on the FRA display. This is apparent when the load isn’t
equal to the generator impedance setting.
“
Level”:
The “bottom right” level displays the output rms
voltage from the system under test.
