R&S ZVA Alignment
1177.5333.02 2.7 E-11
Installation of the Alignment Program
Install the program by double-clicking the setup.exe file.
If you install the program for the second time the install shield will only remove the old installation. You
will have to start the setup.exe again to perform the installation. The tool has been tested with Windows
XP and Windows NT. Connect the PC, ZVA, power meter and signal generator via the IEC/IEEE-bus
interface.

see the
“Usermanual.doc” or “Usermanual.pdf” file that comes with the installation packet and is
installed in the directory “ C:\Program Files\Rohde&Schwarz\ZVAB-Service” on the PC.
Checking the Gauge
It is strongly recommended that every test port of the Vector Network Analyzer is gauged prior to its first use.
The gauge must be recalibrated whenever the connector adapter is changed and should be checked
regularly, using the gauge block, for correct zero between adapter changes.

Procedure
1. Ensure the appropriate connector adapter is fitted to the dial gauge.
2. Attach the gauge block to the gauge interface and rotate the dial so that the indication reads zero. Lock
the dial in position by tightening the screw on the side of the dial. Disconnect the gauge block.
3. Mate the connector to be measured to the gauge and note the indication.
4. The connector is "in gauge" if the indication lies between the limits set by the connector specification (see
Table above). For precision type N and 3.5 mm connectors, the calibrated zero indication on the dial
corresponds to one extreme, the other being -76 µm (-0.003 in) (anti-clockwise on the dial).
CAUTION!
Damage to the connector (or the one it is to) may occur if the reading is positive.
5. After use, return the gauge set to its box.
