R&S ZVAB-B44
on network analyzers with FMR7/6 and FMR9
The driver software of the USB-to-IEC/IEEE Adapter (option R&S
ZVAB-B44) must be
installed on the network analyzer. On analyzers equipped with an FMR7/6 or FMR9
front module controller, this installation disables GPIB control from an external PC. A
reinstallation of the NWA firmware (e.g. in repair mode) will resolve the problem; see
chapter 1.9, "Firmware Update"
1.1.7.3
Ground Connector
Connector providing the ground of the analyzer's supply voltage.
Electrostatic discharge
Electrostatic discharge (ESD) may cause damage to the electronic components of the
DUT and the analyzer. Use the wrist strap and cord supplied with the instrument to
connect yourself to the GND connector.
1.1.7.4
Direct Generator and Receiver Access
Option R&S
ZVA<n>-B16, Direct Generator/Receiver Access, provides 3 pairs of SMA
connectors (or smaller connectors, for microwave analyzers) for each test port. <n>
corresponds to the network analyzer type. For detailed ordering information refer to the
product brochure. See also section "Converter Control" in the help system of your net-
work analyzer.
The connectors give direct access to various RF input and output signals. They can be
used to insert external components (e.g. external signal separating devices, power
amplifiers, a ZVAX extension unit etc.) into the signal path in order to develop custom
measurements, e.g. to test high power devices and extend the dynamic range. If no
external components are connected, each OUT/IN loop should be closed using a
jumper.
●
The SOURCE OUT signal comes from the internal RF signal source. The
SOURCE IN signal goes to the test port. A power amplifier can be inserted
between SOURCE OUT and SOURCE IN in order to boost the test port power.
●
The REF OUT signal comes from the coupler and provides the reference signal.
The REF IN signal goes to the receiver input for the reference signal.
●
The MEAS OUT signal comes from the coupler and provides the received (mea-
sured) signal. The MEAS IN signal goes to the receiver input for the measured sig-
nal.
