Defining the output level of the tracking generator
The tracking generator generates a signal at the current R&S FSH frequency. The
nominal output level of the signal is adjustable from 0 dBm to -40 dBm in steps of 1 dB.
M
Press the AMPT key.
M
Press the "TG Output Attenuation" softkey.
The R&S FSH opens an input field to set the output level.
The output level is an attenuation between 0 dB and 40 dB that corresponds to the
output level. If you, e.g., set an attenuation of 0 dB, the output level is 0 dBm. If
you set an attenuation of 40 dB, the output level is -40 dBm.

4.1 Calibrating Measurements
In its default state, the R&S FSH uses factory calibration. Factory calibration is a full 2-
port calibration over the current frequency range (i.e. span) of the R&S FSH. When
factory calibration is active, the status line reads
. In many cases, this calibration
already provides accurate results.
To get the best and most accurate results, however, you have to calibrate the
measurement manually, because factory calibration does not take the actual test setup
into account (e.g. cables). The R&S FSH provides several calibration methods.
