Change the signal generator output level further down
The following settings are used on the generator:
Change the signal generator RF Level in 10 dB steps down.
Observe the FSMR screen for the yellow RECAL message to re-
appear again (at levels about -50 dBm).
RF LEVEL
RECAL
(MANUAL)
As soon as the RECAL flag appears, the FSMR is ready for a next
RF level range change. The calibration of the level difference due to
the range change will be performed.
Press the RF LEVEL hotkey.
The RF LEVEL menu is displayed.
In the RF LEVEL menu press the
RECAL (MANUAL)
softkey.
The RECAL procedure is performed.
A message box appears. The instrument will perform a
measurement in the calibrated range, then change the RF settings
(RF attenuator, IF gain) and then measure again. After the
recalibration measurements with high accuracy are available in the
RF level range 3 (covers levels from -50 dBm to noise level).
The FSMR is now calibrated in all RF level ranges (for RF levels
from -140 dBm to +30 dBm). Measurements in all level ranges can
now be performed with full accuracy. No further calibration is
required, the Autorange function will automatically adapt the level
setting of the FSMR to the input signal.
