9.4.4 Control of Connected R&S SZU
If a R&S SZU is connected to the R&S SMW, the R&S SMW block diagram changes
and resembles the signal routing. The analog I/Q output signal is firmly routed to the
R&S SZU. The I/Q modulator block visualizes the I/Q modulator of the R&S SZU. The
routing is fixed. You can only swap the streams (A and B) at the RF outputs of use the
differential I/Q outputs instead of the default single-ended output.
Figure 9-3: Block diagram of wideband baseband R&S
SMW (R&S
SMW-B9) with connected R&S SZU
1 = RF frequency at the R&S SZU RF output
2 = RF level, nominal level at the R&S SZU RF output (regulated level)
3 = R&S SZU, indicated as waveguide port icon, label and the serial number
4 = I/Q modulator of the R&S SZU
3, 5 = Access to the R&S SZU RF settings (RF block or icon)
6 = Active I/Q analog output, firmly routed to the R&S SZU; the example uses differential output signal
7 = I/Q analog B is disabled, because the differential output of the first path is used
8 = R&S SMW RF settings
9, 10 = RF frequency and level settings at the second R&S SMW RF output
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.
