Power supply connector
To supply the frequency converter, connect the external DC power supply provided
with the converter to the 9 V / 1.1 A DC input. For details, see Chapter 3.5.6.4, "DC
power supply", on page 99.
Always switch the instrument to standby state before removing the power supply.
Risk of instrument damage
The input voltage and current must not exceed the maximum values according to the
rear panel labeling or the data sheet.
Always use the DC power supply included in the delivery to power your frequency con-
verter.
Fuse holder
A fuse of type IEC60127 T1 L/H protects the frequency converter from excess input
voltages at the power supply connector. A fuse of different type protects the diplexer
(see "Fuse panel" on page 92).
For fuse replacement, see Chapter 11, "Maintenance, storage and disposal",
on page 1772.
RF input
Two 3.5 mm input connectors, only used in high frequency mode:
●
RF IN receives the RF source signal from the diplexer. A semi-rigid cable connects
RF IN to the RF HIGH OUT connector on the top side of the diplexer.
●
LO IN receives the local oscillator signal from the R&S ZNA67 network analyzer.
The complete RF connection of the external test set is described in Chapter 3.5.6,
"Connecting the external test sets", on page 93.
Risk of instrument damage
The RF input power at the connectors RF IN and LO IN must not exceed the maximum
values quoted in the data sheet. The maximum values are below the maximum RF
source power of the network analyzer. The "ZNA67EXT-TS" converter type configura-
tion ensures compatible source powers.
Before you connect your external test set to the network analyzer, always select the
"ZNA67EXT-TS" converter type for the respective converter port in the "Frequency
Converter" dialog (see Chapter 3.5.7.2, "Converter configuration", on page 100).
