j
Display
14-character vacuum fluorescent display for showing programmed commands
and measured values.
k
Annunciators
Annunciators light to indicate operating modes and status conditions:
φ
1,
φ
2,
φ
3 Phase 1, 2, or 3 is being controlled or metered.
CV The ac source output is in constant-voltage mode.
CC The 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
l
Voltage/
Frequency
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.
n
Line
This turns the ac source on or off.
o
System Keys
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
p
Function Keys
Function access command menus that let you:
Program output voltage, current limit, frequency, and output waveforms
Turn the output 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
q
Entry Keys
Entry keys let you:
Enter programming values
Increment or decrement programming values
Calibrate the ac source
