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 con-
nect 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> cor-
responds 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 network
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 ampli-
fiers, a ZVAX extension unit etc.) into the signal path in order to develop custom meas-
urements, 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 (measured)
signal. The MEAS IN signal goes to the receiver input for the measured signal.
Input signals
The maximum RF input levels at all SMA inputs according to the front panel labeling or
the data sheet must not be exceeded.
In addition, it is important that the signal fed in at the SMA inputs contains no DC offset,
as this may impair the measurements and even cause damage to the instrument.
1.1.8 Additional Hardware Options
The following hardware options can be mounted on the right of the NAVIGATION and
SUPPORT keypads:
●
Option R&S ZVA-B18, Removable Hard Disk, replaces the internal hard disk by a
removable compact flash card. The compact flash card can be inserted at the front
panel of the instrument. To ensure failure-free operation, avoid placing external
cables close to the compact flash card.
