FIGURE A-1. GPIB COMMANDS
A.10 *RST — RESET COMMAND
*RST
Syntax: *RST
Description: Resets power supply to the reset values. See PAR. 3.3.2 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. 3.3.6.2 and Figure 3-2 for special programming considerations.)
*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: BHK-500-0.4 04-20-2004,E123456, V7.0.
LIST:IND 21 Selects memory location 21.
LIST:CURR 2.35E-1 Sets output current value of memory location 21 to 0.235A.
LIST:VOLT 400 Sets output voltage value of memory location 21 to 400V.
*OPC Allows status bit 0 to be set when pending operations complete
*ESR Returns 129 (128 + 1, power on, bit 7 = 1, operation complete, bit 1 = 1)
*ESR? Returns 1 (event status register cleared by prior *ESR?)
VOLT 415;CURR 1.5E-1 Sets output voltage to 415V, output current to 0.15A,
*OPC? Puts “1” on output bus when command operations are complete.
*RCL 21 Values in memory location 21 recalled (400V, 0.235A).
*RST Power supply reset to power on default state.
*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 250 Power supply voltage commanded to 250V.
VOLT:TRIG 312 Programs power supply voltage to 312V when *TRG received.
INIT:CONT ON Trigger event is initialized.
*TRG Power supply reverts to commanded output voltage of 312V.
*TST? Power supply executes self test and responds with 0 if test completed
successfully, with 1 if test failed.
