Pin Descriptions and Characteristics
The analog interface on the rear of the instrument provides the following capability:
l
Remote control of output voltage and current
l
Remote monitoring of OT, OVP, and CV status.
l
Remote monitoring of output voltage and current measurements
l
Remote output off (and on) function
When the analog interface is enabled, the front panel VOLTAGE or CURRENT controls are disconnected and have no
effect on the output. You also cannot program the output using any other interface (i.e. GPIB, LAN, USB, web browser).
However, reading the instrument output and status is still available using the aforementioned interfaces.
The OVP level and the OCP settings cannot be programmed using the analog interface. They can still be programmed
using the front panel or SCPI commands while the analog interface is enabled.
Specify the Analog Reference Voltage
To specify either a 5 V or a 10 V reference voltage:
Front Panel Menu SCPI Command
Select System\Analog .
Select either the 5V or 10V reference
voltage. Then press
Select .
Not available
Enable the Analog Interface
Analog control of the output must be activated by con-
necting the ANALOG-ENAB input (pin 5) to Digital ground
(pin 4).
When the analog interface is enabled, the front panel
VOLTAGE or CURRENT controls are disconnected and have
no effect on the output.
