Selecting and Mounting a Test Port Adapter
For the R&S
ZVA-Z110E, two test port adapters are available (see
Port Adapter (Waveguide Flange)"
on page 6). Select the appropriate adapter depend-
ing on the DUTs to be measured:
●
Standard adapter:
Use this adapter if you want to measure DUTs with thin pins only.
●
HP/Agilent compatible adapter:
Use this adapter if you want to measure DUTs with thick pins.
DUTs with thin pins can also be connected to the HP/A adapter (useful if you have both
types of DUT). But the connection of DUTs with small pins is more accurate if the stan-
dard adapter is used. The reduced alignment condition can typically be compensated
using two additional pins above and below the waveguide cross-section.
Mount the selected adapter to the waveguide flange of the instrument using the deliv-
ered screws and the included hex ball driver. A tight and accurate connection is essen-
tial for precise calibration and measurement results.
2.4.5
Connecting the Control Cable
The source power of the frequency converter is controlled from the R&S
ZVA vector
network analyzer. Connect the 3-pin control connector at the rear panel of the con-
verter to the [EXTATT CTRL] connector of option R&S
ZVA-B8 at the top right of the
R&S
ZVA front panel using the control cable supplied with the converter.
The numbers below the [EXTATT CTRL] connectors denote the controlled analyzer
ports. Control connector numbers and analyzer port numbers must always be the
same.
For an upgrade of your network analyzer with option R&S
ZVA-B8 "External Attenuator
Control", contact your Rohde & Schwarz service representative.
Option R&S
ZVA-B8 requires the 3.5'' disk drive of the analyzer to be replaced. To
keep cal kit data and other network analyzer data, save them to another storage
medium (e.g. a USB memory stick) before installing this option.

Connecting RF Cables
The connectors RF IN, LO IN, MEAS OUT and REF OUT have to be connected to the
NWA; LO IN can alternatively be connected to an external generator.
