Test Instructions
To ensure that rated specifications are maintained, the following preparations must be made prior to
checking the rated characteristics:
•Unless otherwise specified it is assumed that the R&S ZVAX24 is connected to the R&S ZVA24 USB
cable and Cascade (RJ 45) cable.
•Rated specifications of the R&S ZVAX24 are tested after a warm-up time of at least 1 hour of
R&S ZVA24 and R&S ZVAX24.
•S-Parameters are measured after performing calibrations of the R&S ZVA with test cables at test
ports 1 and 2. This calibration is done with the following settings:
- [ PRESET ]
- [ START : 10 MHz ]
- [ STOP :24 GHz ]
- [ POWER BW AVG : Meas Bandwidth : 1 kHz ]
If test port 2 is female, connect adapter 3.5 mm f-f (item item 4) to the male cable connector
Calibration cal 1 for port 1 source path

R&S ZVAX-B211 installed Y N
R&S ZVAX-B291 installed Y N Y N
Required calibration for test ports 1, 2 m-f, m-m m-m m-f, m-m m-m
Calibration cal 3 for port 3 source path
(If option R&S ZVAX-B253 or -B273 is installed)
Required calibration for test ports 1 and 2 m-m
Calibration cal 2 for port 2 test receiver path
(If option R&S ZVAX-B210, -B252, -B272 or -B292 is installed)
R&S ZVAX-B292 installed Y N
Required calibration for test ports 1 and 2 m-f, m-m m-m
Multiple use of calibrations is possible, cal 1, 2 and 3 may be identical.In the worst case two different
calibrations must be performed (m-m + m-f).
Save calibrations in the cal pool [ MODE : Cal Manager… ].
•Additional uncertainties introduced by the measurement equipment must be taken into account when
checking the rated values
•Values specified in data sheet are guaranteed limits
•Instrument settings required for the measurements are given as follows:
[<KEY>]Press a key on the front panel, e.g. [SPAN]
[<SOFTKEY>] Press a softkey, e.g. [MARKER -> PEAK]
[<nn unit>] Enter a value and terminate by entering the unit, e.g. [12 kHz]
Successive entries are separated by [:], e.g. [ BW : MANUAL RES BW : 3 kHz ]
