FIGURE A-1. GPIB COMMANDS
A.10 *RST — RESET COMMAND
*RST
Syntax: *RST
Description: Resets power supply to the reset state. See PAR. 3.2.8 for a detailed description of the reset state.
Reset is also affected by DCL (Device Clear) control, described in PAR. 3.3.2. In addition, *RST also
causes the unit to store the following parameters:
INIT:CONT 0, LIST:DIR UP and DISP:MODE NORMAL (See example, Figure A-1.)
A.11 * SAV — SAVE COMMAND
*SAV
Syntax: *SAV (1 to 40)
Description: Saves the present state of output voltage, output current, overvoltage and overcurrent to the
specified memory location. This command stores the present state of the power supply to one of 40
memory locations. The following parameters are stored by *SAV: CURR[:LEV][:IMM],
VOLT[:LEV][:IMM], CURR:PROT[:LEV] and VOLT:PROT[:LEV]. The stored values can be restored by
the *RCL command. (See PAR. 3.3.5.2 and Figure 3-2 for special programming considerations.) (See
example, Figure A-1.)
*CLS Power supply clears status data.
*ESE 60 Power supply enables bits 5, 4, 3 and 2, allowing command error, execution
error, device dependent error and query error to set the Event Status
Summary bit when an STB? query is executed.
*ESE? Returns 60, (value of the mask) verifying that bits 5, 4, 3 and 2 are enabled.
*ES Unknown command will set command error (Bit 5).
*ESR? Returns 32 (bit 5 set), indicating Command Error has occurred since the last
time the register was read.
*IDN? Power supply returns: KEPCO, BHK-1000-.04 04-20-2004,E123456, V7.0.
*OPC Allows status bit 0 to be set when pending operations complete
VOLT 250;CURR 3E-2 Sets output voltage to 250V, output current to 30mA
*SAV 33 The present state of the power supply is stored in memory location 33.
*ESR? Returns 1 (event status register cleared by prior *ESR?)
VOLT 215;CURR 15E-3 Sets output voltage to 215V, output current to 15mA,
OUTP ON Programmed voltage appears at output terminals.
*OPC? Puts “1” on output bus when command operations are complete.
*RCL 33 Values in memory location 33 recalled (250V, 30mA).
*RST Power supply is reset.
*SRE 40 When ESB or QUES bits are set (Table A-3), the Request for Service
bit will be set.
*SRE? Returns the value of the mask (40).
*STB? For example, the Power supply responds with 96 (64 + 32) if MSS and the
Event Status Byte (Table A-3) summary bit have been set. The power sup-
ply
returns 00 if no bits have been set.
VOLT 220 Power supply voltage commanded to 220V.
OUTP ON Programmed voltage appears at output terminals.
VOLT:TRIG 212 Programs power supply voltage to 212V when *TRG received.
INIT:CONT ON Trigger event is initialized.
*TRG Power supply reverts to commanded output voltage of 212V.
*TST? Power supply executes self test and responds with 0 if test completed
successfully, with 1 if test failed.
