8 = Active I/Q analog output, firmly routed to the R&S SZU; the example uses differential output signal
9 = I/Q analog B is disabled, because the differential output of the first path is used
10 = R&S SMW RF settings
The R&S SMW controls the R&S SZU as it is its embedded unit. You access the R&S
SZU settings directly from the R&S SMW block diagram. The access is identical to the
access of the R&S SMW RF settings but the list shows only the supported settings.
For example:
●
To access the R&S SZU RF settings, select the R&S SZU icon.
●
To access the I/Q modulator settings of the R&S SZU, select the "I/Q Mod" block.
The R&S SMW RF settings are dedicated to the R&S SZU. The corresponding RF
output cannot be used for other application, like, for example, LO coupling.
As with other downstream instruments, the frequency and level indications in the
R&S SMW status bar show the R&S SZU values. Parameters like the frequency and
level offset, level limits, delta phase or RF output state affect the RF output of the R&S
SZU.
The remote commands required to define the R&S SZU settings are the same as the
R&S SMW commands, so that you can reuse your SCPI scripts. Note the changes in
the value ranges and the commands usage listed in chapter "Remote Control" in the
description SZU100A Getting Started.
