Manual background

*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 1-2, 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]	OUTP:REL:POL
CURR:PROT:STAT	OUTP:PROT:DEL	VOLT[:LEV][:IMM]
DIG:DATA[:VAL]	OUTP:REL[:STAT]	VOLT:PROT[:LEV]

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).
