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.
