7.8 Adjusting Settings Automatically
Access: "Overview" > "Amplitude"/"Frequency" > "Auto Settings"
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. You can
configure this measurement.
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 %
