This section gives an overview of the rear panel controls and connectors of the network analyzer.
The rear connectors are described in detail in the annex Hardware Interfaces in the online help
system.
•
IEC Bus is the GPIB bus connector (according to standard IEEE 488 / IEC 625).
•
AUX is an auxiliary connector, to be wired as needed. AUX is not fitted on standard instruments.

mouse or other pointing device.
•
10 MHz REF serves as an input or output for the 10 MHz reference clock signal.
•
DC MEAS comprises two inputs for DC measurements, specified for different voltage ranges.
•
PORT BIAS comprises up to four inputs for an external DC voltage (bias) to be applied to the test ports.
Each PORT BIAS input is protected by an exchangeable fuse.
•
MONITOR is a sub-Min-D connector used to connect and external VGA monitor.
•
USER CONTROL is a D-sub connector used as an input and output for low-voltage (3.3 V) TTL control
signals.
