Some settings can be adjusted by the R&S FPL1000 automatically according to the

current measurement settings. In order to do so, a measurement is performed. The

duration of this measurement can be defined automatically or manually.

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 function for a triggered measurement, you

are asked how the R&S FPL1000 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 %
