1164.0696.92 14 E-4

R&S®ZV- Z58/Z59 Automatic Calibration
2 Automatic Calibration
The calibration unit is an integrated solution for automatic system error calibration of vector network
analyzers of the R&S ZVAB family with 1 to 8 ports. It is especially suited for the 8-port vector network
analyzers R&S ZVT. The unit contains calibration standards that are electronically switched when a
calibration is performed. The calibration kit data for the internal standards is also stored in the
calibration unit, so that the analyzer can calculate the error terms and apply the calibration without any
further input.
Automatic calibration is generally faster and more secure than manual calibration:
•There is no need to connect several standards manually. The number of connections to be
performed quickly increases with the number of ports.
•Invalid calibrations due to operator errors (e.g. wrong standards or improper connections) are
almost excluded.
•No need to handle calibration kit data.
•The internal standards do not wear out because they are switched electronically.
Contents of this Technical Information
This Technical Information gives a brief introduction to the unit’s connection and use.
For detailed information refer to the help system of your network analyzer.
USB Connection to the Network Analyzer
The calibration unit provides the following connectors:
•A USB type B connector at the front panel is used to control the unit. A USB cable for connection to
the network analyzer is provided with the calibration unit.
•Eight or six RF connectors numbered 1 to 8 (6) are to be connected to the test ports of the
analyzer. The two alternative R&S ZV-Z59 cal unit models 1164.0638.38 and 1164.0638.78 are
equipped with 3.5 mm (f) or type N (f) sockets, respectively. The R&S ZV-Z59 cal unit provides
3.5 mm sockets.
To connect the unit...
1. Switch on and start-up your network analyzer.
2. Wear a grounded wrist strap; see EMI Protective Measures on p. 12 ff.
3. Connect the USB type A connector of the USB cable to any of the USB type A connectors on the
front or rear panel of the analyzer and the USB type B connector of the USB cable to the USB type
B connector on the front panel of the calibration unit. You can also connect the unit before switching
on the analyzer.
4. Wait until the operating system has recognized and initialized the new hardware. When the unit is
connected for the first time, this may take longer than in normal use.
The unit is ready to be used as outlined below.
1164.0696.92 15 E-4

Automatic Calibration R&S® ZV-Z58/Z59
Performing an Automatic Calibration
After connection and initialization, you can use the calibration unit as follows:
1. Connect ports n analyzer ports (n = 1 to 8 (6), depending on your analyzer and cal unit model and
the number of ports to be calibrated) to n arbitrary ports of the calibration unit. Terminate all unused
ports (no. n + 1 to 8) with a 50 Ωmatch.
2. Perform the automatic calibration for the selected number of ports using the Measurement Wizard
or the Start Calibration menu. For details refer to the analyzer’s help system.
3. Remove the test cables from the unit, connect your DUT instead and perform calibrated
measurements.
Tip for Cabling
The cabling of test ports is easiest if the calibration unit is placed on top of the
analyzer; see figure below.
1164.0696.92 16 E-4

R&S®ZV- Z58/Z59 Automatic Calibration
Accuracy Considerations
To ensure an accurate calibration, please observe the following items:
•Unused ports of the calibration unit must be terminated with a 50 Ωmatch.
•No adaptors must be inserted between the calibration unit and the test ports.
•After connecting the unit to the USB port, allow for a sufficient warm-up time (see data sheet)
before starting the calibration.
•To ensure best accuracy the analyzer automatically reduces the source power to –10 dBm. If the
test setup contains a large attenuation, deactivate Automatic Power Reduction for Calibration Unit
in the initial tab of the System Config dialog and ensure an input power of –10 dBm at the ports of
the calibration unit (please also refer to the data sheet).
The calibration type depends on the number of ports. If a single port is calibrated, the analyzer uses full
one port calibration. For 2 and more ports, TOSM calibration is used.
