About the R&S SZU IQ Upconverter
The R&S SZU generates a vector-modulated signal by converting the baseband
signal to the output frequency range of 58.32 GHz to 64.8 GHz (center frequency).
The R&S SZU receives the differential or single ended baseband signals (I/Q),
and an LO signal in the range of 1.944 GHz to 2.16 GHz from the R&S SMW.
The USB host interface is the communication port of the R&S SZU to the
R&S SMW. As external instrument, the R&S SZU is configured in the "System
Configuration" dialog of the R&S SMW, and indicated by a symbol in the GUI.
Once connected, the R&S SMW reads the calibration data of the R&S SZU, and
8Manual 1425.3061.02 ─ 04
Page 9
R&S®SZU100A
adjusts the frequency and level values to the output values of this downstream
instrument.
Thus the R&S SMW controls the R&S SZU almost entirely. You only need to
select single ended or differential mode for the baseband connection. It is recommended that you work in differential mode due to better common mode noise
suppression over the single ended connection. When you work with two
R&S SZUs on one R&S SMW, you must work in single ended mode.
The setting parameters in the R&S SMW remain the same.

Measurement Setup
Electromagnetic interference (EMI) affects the measurement results
To suppress generated electromagnetic interference:
●
Only use the enclosed cables set, as the R&S SZU has been calibrated
with these cables.
You can find out the corresponding cable set by the serial number,
which is the same as the serial number of the R&S SZU.
●
Always terminate open cable ends:
– Terminate the waveguide output with 50 Ohm.
If it is not possible to terminate the output with 50 Ohm, leave it
open.
– Instead of terminating with 50 Ohm, you can connect a wideband
power sensor of the R&S NRPxx series, which also provides a good
termination.
●
Use only the USB cable included.
Startup
●
Note the EMC classification in the data sheet.
7.2 Measurement Setup
This section provides the first steps for putting the R&S SZU into operation. The
startup also comprises the access to the settings made in the R&S SMW.
Risk of RF connector and cable damage
Excessive tightening of the connectors can damage the cables and connectors. Too weak tightening leads to inaccurate results.
Always use the torque wrench suitable for this type of connector, see
"Mounting the test port adapter" on page 14.
The figure shows the basic test setup of an application with the R&S SZU IQ
Upconverter. The R&S SMW controls the R&S SZU via USB. The R&S SMW also
provides the analog baseband signal, and a trigger signal optionally. The

7.4 Running Internal Adjustments
To optimize the accuracy for the application with the R&S SZU, you can execute
calibration routines directly in the R&S SMW.
When to perform the internal adjustments?
We recommend that you perform the internal adjustment:
●
When setting up an application the first time.
●
When changing the I/Q output type of an already set measurement.
When you have calibrated the R&S SZU with a different I/Q output type (single-ended / differential), the R&S SMW issues the warning message:
30Manual 1425.3061.02 ─ 04
Page 31
R&S®SZU100A
Running Internal Adjustments
"SZU settings conflict: At least one adjustment has been done in another
mode than the SZU is currently set to (single-ended / differential). Accuracy
may be affected!"
To adjust the R&S SZU ...
Set up the measurement, if not done yet. Observe the requirements as described
under Chapter 7.1, "System Requirements", on page 19:
1. Make sure that the serial number of the R&S SZU and the cables match.
2. Connect the R&S SZU to the R&S SMW, see Chapter 7.2, "Measurement
Setup", on page 20.
3. Make sure that:
● You have terminated the waveguide port properly, see Electromagnetic
interference (EMI) affects the measurement results.
Do not leave the protective cap plugged on the waveguide output either, as
it causes undefined reflections and thus leads to incorrect adjustments.
● No power is fed into the waveguide output during the internal adjustment
processes. It can be caused, e.g. by a connected spectrum analyzer which
emits LO power when operating in receiving mode.
Startup
4. Configure the R&S SZU in the R&S SMW, see Chapter 7.3, "Starting Up",
on page 22.
5. Make sure, that you have selected the correct I/Q output type (single ended or
differential).
6. Perform the connection test, see To configure the R&S SZU in the
R&S SMW ... > step 6.
7. In the R&S SMW, select "System Config > Setup > General > Internal Adjustments".
In this dialog you can perform the internal calibration routine for the R&S SZU,
when connected.

Startup
Behavior of the R&S SMW When Working with the R&S SZU
The R&S SMW adjusts the internal calibration routines to the R&S SZU.
"Adjust All" is disabled, i.e. in this configuration, you cannot execute adjustment routines for the R&S SMW.
8. Select "Adjust External Frequency Converter A/B" for all R&S SZU.
The R&S SMW automatically calibrates the parameters of the externally connected R&S SZU.
9. When completed, check that no errors occurred.
If the internal adjustments detect any errors, see User Manual of R&S SMW,
chapter Internal Adjustment Settings for further information on how to proceed.
7.5 Behavior of the R&S SMW When Working with
the R&S SZU
At startup, the R&S SMW firmware takes control of the R&S SZU almost entirely.
You can only select the analog I/Q connection (differential or single ended), provided you are working with only one R&S SZU.

R&S®SZU100A
Behavior of the R&S SMW When Working with the R&S SZU
The R&S SZU behaves as if it is an internal assembly.
The following section outlines the behavior at the corresponding states.
At startup or repeated plugging
●
The R&S SMW adds a connected R&S SZU to the list of external instruments.
Vice versa, the R&S SMW removes an R&S SZU from the list, when it is disconnected.
●
If "Auto connect" is enabled, the R&S SMW establishes the connection automatically, provided the R&S SZU is assigned to an I/Q output.
●
The R&S SMW adopts the related minimum and maximum values of the
R&S SZU.
Furthermore, it obtains the calibration data of the R&S SZU. If these calibration data confirm a wider frequency range as given in the data sheet, you can
enable the frequency overrange in the "RF Frequency" setting dialog of the
R&S SMW.
Startup
The R&S SMW adjusts the resulting frequency range also in the status bar.
33Manual 1425.3061.02 ─ 04
Page 34
R&S®SZU100A
Startup
Behavior of the R&S SMW When Working with the R&S SZU
1 = Frequency range with overrange enabled
2 = Frequency range with overrange disabled
Note: The performance in the extended range can deviate from the specified
values given in the data sheet.
●
You can connect and configure the R&S SZUs only in the predetermined
paths, see "Two R&S SZU connected to the R&S SMW" on page 28
The R&S SMW displays error messages, if the connection and the assigned
ports do not match, or, e.g., the connection is interrupted.
●
When disconnected in the "External RF and I/Q" dialog (or via remote control),
the R&S SMW retains the R&S SZU in the list of instruments and at the
assigned output. It presets the R&S SZU and the parameters of the "I/Q Analog Outputs", the "I/Q Modulator" and the "RF" path, and turns off the RF output. Not affected settings remain.
During operation
●
In the status bar, the indicated frequency and level values correspond to the
RF signal at the output of the R&S SZU.
Settings like, e.g. level offset or level limit also affect the RF output of the
R&S SZU.
●
The firmware of the R&S SMW controls the affected I/Q output parameters
automatically, i.e. except of the "I/Q Output Type", the settings are read only.
●
The R&S SMW disables list mode, analog modulations and LO coupling.
At preset
●
If "Preset behavior: Keep connections to external instruments" is enabled, the
R&S SZU remains connected to the R&S SMW, if the USB and I/Q connections still exist physically.
The R&S SMW presets the RF parameters to the R&S SZUs default values
("RF Off", "RF Freq = 60 GHz", "RF Level = 30 dBm").
The "Frequency Overrange" setting is not affected. It is reset only by factory
preset.
●
If "Preset behavior: Keep connections to external instruments" is disabled, the
R&S SMW presets the R&S SZU, cuts the connection and presets to its
default values.
It also resets the "Frequency Overrange".
●
If no R&S SZU is connected, the R&S SMW presets to its default values ("RF
Off", "RF Freq = 1 GHz", "RF Level = 30 dBm").

Page 35
R&S®SZU100A
Behavior of the R&S SMW When Working with the R&S SZU
At reboot
●
If "Auto connect" is enabled, the R&S SMW establishes the connection automatically, provided the USB connection exists and the R&S SZU is assigned
to an I/Q output
●
If "Auto connect" is disabled, the state remains disconnected, the entry in the
list of external instruments still exists.
At recall
Applies the settings from a saved configuration.
For a proper configuration, load saved configurations that fit to the current
setup.
Do not load a saved configuration of a connected R&S SZU and R&S SMW
in a standalone R&S SMW and vice versa.
Startup
Mismatch between the setup and the loaded configuration leads to wrong
frequency indication in the status bar. The output frequency is correct and
corresponds to the current setup.
In setups with R&S SZU and R&S SMW, always establish the connection
between the two instruments and load a saved configuration with a connected
setup.
