Rear-panel familiarization
The Model 2290-5 rear panel is shown below. Descriptions of the controls on the rear panel follow the
figure.

Power entry
The power entry module contains the line fuse, the line voltage selection,
and includes filtering to block high-frequency noise from entering or exiting
the unit. Refer to the Safely connect to instruments topic for instructions on
selecting the correct line voltage and fuse.
HIGH VOLTAGE output
port
The HIGH VOLTAGE output port is an SHV male port that connects the
Model 2290-5 source output to external equipment. SHV-to-SHV and SHV-
to-MHV mated high voltage cables are available.
Analog I/O
The SET/MON and I MON BNC jacks provide voltage and current monitor
signals, or an external voltage control input and current monitor, depending
upon the setting of the VOLTAGE select switch. If the switch is in the MON
(monitor) position, the front panel controls the voltage. If the switch is in the
SET position, the rear panel analog voltage will control the output voltage
When the VOLTAGE select switch is in the MON (monitor) position, both
jacks are 0 to +10 V outputs corresponding to 0 to full scale. For example, if
the voltage source output is 2 kV, the SET/MON
jack output voltage will be 4
V.
IEEE-488 STD PORT
The 24-pin IEEE-488 (GPIB) port allows computer control of the Model
2290-5.
INTERLOCK port
The contacts of the interlock port allow an external limit switch in the
connector path. The circuit must be engaged to allow high-voltage output.
