3.5.5.1 Configure the external test sets in the analyzer firmware
Before connecting the RF cables, make sure that the converter configuration is set up
correctly on the R&S ZNA (see Chapter 3.5.7.2, "Converter configuration",
on page 100).
3.5.5.2 Connect the external test sets
Each of the external test sets must be connected to the R&S ZNA, the power supply
and the DUT. Please refer to the following sections for details.
●
H/L SWITCH (control connection): Chapter 3.5.6.3, "Diplexer control", on page 98
●
RF and IF connections: See Chapter 3.5.6.2, "RF and LO cabling", on page 96
●
Power supply: See Chapter 3.5.6.4, "DC power supply", on page 99
●
DUT (usually connected after calibration): See Chapter 3.5.7.6, "Mounting a DUT",
on page 106
3.5.5.3 Switch on the external test sets
The standby toggle switch is located at the rear panel (see "Standby switch"
on page 86). To switch the external test set to ready state, press the key. The green
LED next to the switch must be lit now.
After switching the external test set to the ready state, a warm-up time of one hour is
required to ensure accurate measurements. The instrument is only warmed-up in
ready state, not in standby state.
3.5.6 Connecting the external test sets
The R&S ZNA67EXT is delivered with fully assembled external test sets, each consist-
ing of a diplexer R&S ZVA-ZD110 and a frequency converter R&S ZVA-Z110. The
"internal" connection between the diplexers and frequency converters is described in
Chapter 3.5.4.3, "Diplexers", on page 88.
System component information
A label on the rear panel of the network analyzer shows the diplexer and converter
units with their position. The label contains the following information.
