CALibration Subsystem
The CALibration system contains the commands needed for calibrating the R&S
SGU.
R&S
SGU cannot be calibrated on its own. Therefore a connection with a signal gener-
ator (local oscillator (LO)) is needed. If you use a compatible R&S signal generator,
then the calibration process will be completed automatically after starting the calibra-
tion process. Otherwise you have to follow the steps described in
on page 151. We assume that a remote PC is connected to the
instruments, the remote PC and the instruments are switched on and a connection
between them is established.
The selftest of an R&S SGU also requires a similiar instrumental setup. You can per-
form the selftest and read its results using the commands
and

Calibration process of the R&S SGU
Figure 11-1: Calibration process of the R&S SGU. No physical connections between the instruments
are shown in this graphic.
In order to complete the calibration process you have to complete the following steps:
1. Start an adjustment request with the SCPI com-
mand
:CALibration:xxx:STARt
, where
xxx
stands for
IQModulator
,
IQModulator:LOCal
or
LEVel
.
2.
a) Query R&S
SGU for the required LO settings with the SCPI command
