Command Summary
Introduction
Table C-1 provides an alphabetical listing and a brief description of each command that can be sent to the Agilent 6621A-
24A, and 6627A power supplies. All of the commands can be executed remotely over the GP-IB. Many of the commands
can also be executed locally from the supply’s front panel as indicated in the table.
Command headers are accepted in upper or in lower case letters although only upper case letters are used in this summary.
The brackets < > indicate a number to be sent. Note that <ch> must specify an output channel number from 1 through 4 as
applicable. Commas or spaces are required between numbers. Spaces are optional between the command header and the
first number. No commas are allowed between header and first number. Use semi-colons between multiple commands sent
in one statement.
Chapter 5 gives a complete description (including syntax) of most of the commands listed. Calibration commands are
described in Appendix A. Two of the commands listed (ROM? and VMUX?) are described in the Service Manual.
Table C-1. Command Summary
Command Description
ASTS? < ch > Queries the accumulated status (ASTS) of the specified output channel. The
response (integer 0-255) represents the sum of the binary weights of the ASTS
register bits (see page 74). The ASTS register is automatically set to the present
status after being queried.
CLR Returns the entire power supply (all outputs) to the power on state except that the
supply is not unaddressed and its store/recall registers are not changed (see Clear
Command page 73).
CMODE <on/off> Turns the calibration mode on or off. On/off is a 1 to turn the calibration mode on;
a 0 turns it off (see Appendix A).
CMODE? Queries if the calibration mode is on or off. Response is either a 1 (on) or 0 (off),
(see page 79).
*DLY < ch >, < delay > Sets the reprogramming delay for the specified output channel. This delay is used
to mask the CV, + CC, - CC, and UNR status bits from the fault register and the
OCP function for the specified delay period (0 to 32 seconds). The delay time is
initiated after a VSET, ISET, OUT, RCL, OVRST, or OCRST command is sent
(see Reprogramming Delay, page 78).
DLY? < ch > Queries the present reprogramming delay of the specified output channel (see page
78). The response can be a real number from 0.000 to 32 seconds (e.g., .450
seconds).
DSP < on/off > Turns the power supply’s front panel display either on or off (see page 78). On/off
equals 1 to turn the display on or a 0 to turn it off.
* Indicates that the command can be executed from the front panel.
