7.2.4 Configuring the Tracking Generator
If your R&S FSH features a tracking generator, you can define several characteristics
of the generated signal.
► Press the AMPT key.
► Press the "TG Settings" softkey.
You can define the level of the generated signal as an absolute level or an
attenuation (value relative to 0 dBm).
► Select the “TG Power” menu item to define an absolute level.
► Select the “TG Attenuation” menu item to define a relative level.
An input of 10 dB, for example, corresponds to an attenuation of -10 dBm.
In addition, you can define an arithmetic level offset, for example to take external
attenuators into account.
► Press the "TG Settings" softkey.
► Select the “TG Power Offset” menu item to define a level offset.
Note the the level offset has no effect on the actual signal level.
Tracking generator output level
Using an output level of 0 dBm (or a receiver attenuation of 0 dB) for S12 or S21
measurements can cause an overload at the RF input. It is therefore recommended to
use an output level of -10 dBm (default) or lower for these measurements.
This especially applies to measurements on amplifiers.
