Adjusting settings automatically during triggered measurements
When you select an auto adjust function a measurement is performed to determine the
optimal settings. If you select an auto adjust funtion for a triggered measurement, you
can select how the R&S
ESR should behave:
●
(default:) The measurement for adjustment waits for the next trigger
●
The measurement for adjustment is performed without waiting for a trigger.
The trigger source is temporarily set to "Free Run". After the measurement is com-
pleted, the original trigger source is restored. The trigger level is adjusted as fol-
lows:
–
For IF Power and RF Power triggers:
Trigger Level = Reference Level - 15 dB
– For Video trigger:
Trigger Level = 85 %

Auto Freq
Defines the center frequency and the reference level automatically by determining the
highest frequency level in the frequency span. This function uses the signal counter;
thus it is intended for use with sinusoidal signals.
