*PSC causes a write cycle to nonvolatile memory. If *PSC is programmed to 0, then the *ESE and
*SRE commands also cause a write cycle to nonvolatile memory. The nonvolatile memory has a finite
number of write cycles (see Table A-2, Supplementary Characteristics). Programs that
repeatedly write to nonvolatile memory can eventually exceed the maximum number of write cycles
and may cause the memory to fail.
*RCL
Meaning and Type
Recall Device State
Recalling a previously stored state may place hazardous voltage at the power supply output.
Description
This command restores the power supply to a state that was previously stored in memory with a *SAV command to the
specified location. The following states are recalled:
CURR[:LEV][:IMM]
OUTP[:STAT]
CURR:PROT:STAT
OUTP:PROT:DEL
DIG:DATA[:VAL]
OUTP:REL[:STAT]
Sending *RCL also does the following:
•
Forces an ABORt command before resetting any parameters (this cancels any uncompleted trigger actions).
•
Disables the calibration function by setting CAL:STATe to OFF.
•
Sets display functions as follows:
•
DISP[:WIND][:STATe] to ON.
•
DISP[:WIND]:MODE to NORMal.
•
DISP[:WIND]:TEXT to ' '.
•
Sets INIT:CONT to OFF.
•
Sets TRIG:SOUR to BUS.
At power turn-on, the power supply normally is returned to the factory defined turn-on state (see *RST). However, it also
may turn on to the state stored in location 0 (see Turn-On Condition under "Chapter 5 - Front Panel Operation" of the power
supply Operating Guide).
