Table C-l. Command Summary (continued)

Command

 

Description

 

 

 

SRQ?

 

Queries the present setting of the reasons for issuing an SRQ (see page 76).

 

 

Response is 0, 1, 2, or 3 that corresponds with the SRQ <setting> described

 

 

previously.

*STO < reg >

 

Stores the present voltage and current settings for all output channels in the

 

 

specified register (1 to 10); see page 72. These settings can be recalled when

 

 

desired (see RCL command).

STS? <ch>

 

Queries the present status of the specified output channel. The response (integer

 

 

0-255) represents the sum of the binary weights of the status register bits (see

 

 

page 74).

TEST?

 

Causes the power supply to perform a self test of its HP-IB interface. The response

 

 

Is 0 if the test passes or an integer failure code (see Test Query, page 79).

VDATA <ch>, <Vlo>, <Vhi>

 

Sends data to calibrate the voltage setting and readback circuits of the specified

 

 

output channel. Vlo and Vhi are measured values which the supply uses to

 

 

calculate correction constants (see Appendix A).

VHI < ch >

 

Causes the voltage of the specified output channel to go to the high calibration

 

 

point (see Appendix A).

VLO < ch >

 

Causes the voltage of the specified output channel to go to the low calibration

 

 

point (see Appendix A).

VMUX? < ch >, < input >

 

Queries the measurement of the input (1 to 8) to the analog multiplexer on the

 

 

specified output board. See Service Manual.

VOUT? < ch >

 

Queries the measured output voltage of the specified output channel (see Voltage

 

 

Programming, page 69). The response is a real number. The front panel display

 

 

can be used to monitor the measured output voltage (and current) of the selected

 

 

output channel.

* VSET < ch >, < voltage >

 

Sets the voltage of the specified output channel (see page 69).

* VSET? < ch >

 

Queries the present voltage setting of the specified output channel (see page 69)

 

 

The response is a real number.

*UNMASK < ch >, < setting >

 

Sets the bits in the mask register of the specified output channel to the setting

 

 

(integer from 0 to 255). The mask register operates in conjunction with the status

 

 

and fault registers (see page 74).

*UNMASK? < ch>

 

Queries the present setting of the mask register of the specified output channel

 

 

(see page 74). The response is an integer from 0 to 255.

 

 

 

*Indicates that the command can be executed from the front panel.
