Standard Commands for Programmable Instruments (SCPI)
92
If the command parameter =
0, then the above registers are not cleared at power turn on, but are programmed to their last
previous state. This can enable the power supply to request service at turn on. Any non-zero parameter causes both registers
to be cleared at turn on, preventing the power supply from being capable of requesting service at that time. See "Status
Reporting" for details of these registers.
*PSC causes a write cycle to nonvolatile memory. Non volatile memory has a finite maximum number of
write cycles. Programs that repeatedly cause write cycles to nonvolatile memory can eventually exceed the
maximum number of write cycles and cause the memory to fail.
Command Syntax *PSC <bool>
Parameters 0 or l
Default Value 0
Example *PSC 0 *PSC 1
Query Syntax *PSC?
Returned Parameters <NR1> 0 or 1
*RCL
Meaning and Type
Recall
Device State
Recalling a previously stored state may place a hazardous voltage at the power supply output.
Description
This command restores the power supply to a state that was previously stored in memory with the *SAV command to the
specified location. The following parameters are affected by *RCL:
CURR[:LEV][:IMM] OUTP[:STAT] OUTP:REL:POL
CURR:PROT:STAT OUTP:PROT:DEL VOLT[:LEV][:IMM]
OUTP:RE~[:STAT]
Sending *RCL also does the following:
♦ forces an
ABORt command before resetting any parameters (this removes all pending trigger levels)
♦ forces an
OUT:PROT:CLE command before resetting any parameters (this clears all status conditions)
♦ sets
INIT:CONT to OFF
♦ sets TRIG:SOUR to BUS
Command Syntax *RCL <NRf>
Parameters 0 through 4
Example *RCL 3
