R&S FSMR Measurement Receiver Mode
1166.3363.12 4.4-43 E-2
MEAS TIME
AUTO
The MEAS TIME AUTO softkey activates the automatic coupling of measurement
time.
Mode Measurement time
RF Level 100 ms
Audio 100 ms
Demod 100 ms
IEC/IEEE bus command:
SENS:SWE:TIME:AUTO ON
To obtain a correct result display, at least five periods of the demodulated signal
should be monitored. If the modulation frequencies are low, it may be useful to
manually prolong the measurement time (= signal monitoring time).
IEC/IEEE bus command:
SENS:SWE:TIME:AUTO ON
MEAS TIME
MANUAL
The MEAS TIME MANUAL softkey opens the entry field for determining the data
acquisition time. The permissible value range depends on the selected
demodulation bandwidth:
