MSRA/MSRT operating mode
In MSRA and MSRT operating mode, settings related to data acquisition can only be
adjusted automatically for the MSRA/MSRT Master, not the applications.
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 FSW 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 %

Adjusting the Center Frequency Automatically (Auto Frequency)
The R&S FSW adjusts the center frequency automatically.
The optimum center frequency is the frequency with the highest S/N ratio in the fre-
quency span. As this function uses the signal counter, it is intended for use with sinus-
oidal signals.
