14-character vacuum fluorescent display for showing programmed commands and measured values.

Annunciators light to indicate operating modes and status conditions:

φ1 Phase 1 is being controlled or metered.

CV The ac source output is in constant-voltage mode.

CCThe ac source output is in constant-current mode. Unr The ac source output is in an unregulated state.

Dis The ac source output is disabled (off).

Tran The ac source output is initialized to output a transient. OCP The overcurrent protection state is enabled.

Prot One of the ac source’s output protection features is activated. Cal The ac source is in calibration mode.

Shift The Shift key is pressed to access an alternate key function. Rmt The selected interface (GPIB or RS-232) is in a remote state. Addr The interface is addressed to talk or to listen.

Err There is a message in the SCPI error queue.

SRQ The interface is requesting service from the controller.

Meter Front panel measurement functions are: ac only, dc only, or ac+dc

AC+DC

Output The ac source output coupling is: ac only, or ac+dc

AC+DC

The rotary pulse generators let you set the output voltage and frequency when the ac source is in local mode. Their response is rate sensitive.

Turning a control rapidly provides coarse control of the value. Turning a control slowly provides fine control of the value.

This turns the ac source on or off. The system keys let you:

Return to Local mode (front panel control) Set the ac source GPIB address

Set the RS-232 interface communication baud rate and parity bit Display SCPI error codes and clear the error queue

Save and recall up to 4 instrument operating configurations Function access command menus that let you:

Program output voltage, current limit, frequency, and output waveforms Turn the ouput on and off

Select metering functions

Send immediate triggers from the front panel Program transient output functions

Set and clear protection functions Select output phases

Select the coupling for output and meter functions Monitor instrument status

Entry keys let you:

Enter programming values

Increment or decrement programming values

Calibrate the ac source
