R&S FSQ Signal Analyzer - Rohde & Schwarz

R&S FSQ Instrument Functions
SOURCE CAL
Tracking Generator – Option R&S FSU-B9
The permissible setting range is -200 dB to +200 dB in steps of 0.1 dB. Positive offsets
apply to an amplifier and negative offsets to an attenuator subsequent to the
tracking generator.
The default setting is 0 dB. Offsets 0 are marked by the activated enhancement
label LVL.
Remote command: SOUR:POW:OFFS -10dB
4.7.2 Transmission Measurement
This measurement will yield the transmission characteristics of a two-port network.
The built-in tracking generator serves as a signal source. It is connected to the input
connector of the DUT. The input of the R&S FSQ is fed from the output of the DUT.

A calibration can be carried out to compensate for the effects of the test setup (e.g.
frequency response of connecting cables).

The SOURCE CAL softkey opens a submenu comprising of the calibration functions
for the transmission and reflection measurement.
For information on the calibration of the reflection measurement
(CALREFLSHORT and CAL REFL OPEN) and its mechanisms, refer to section
“Calibration of Reflection Measurement” on page 4.228.
To carry out a calibration for transmission measurements the whole test setup is
through-connected (THRU).
