FIGURE B-2. USING MEMORY LOCATION COMMANDS AND QUERIES
B.19 MEMory:PACK COMMAND
MEM:PACK
Syntax: Short Form: MEM:PACK Long Form: MEMory:PACK
Description: Compresses flash memory. When the memory is out of space, the internal microprocessor copies
the live data to a backup flash area, erases the main flash data area, copies the current control vari-
ables into this clean space and then erases the backup flash area. The pack process can take 500 mil-
liseconds to complete. Refer to PAR. 3.6.3.6 for MEM:PACK details
B.20 MEMory:UPDate COMMAND
MEM:UPD
Syntax: Short Form: MEM:UPD {INT | LIM | SER | CONT | OUTP}
Long Form: MEMory:UPDate {INTerface | SERial | LIMits | CONTrast | OUTPut}
Description: Saves selected variables. MEM:UPD INT saves GPIB address, Language (SCPI or CIIL), SYST:SET
(PAR. B.178) variables and the state of OUTP:CONT (see PAR. B.23). MEM:UPD SER saves the
serial communication state, baud rate, pace control and echo information. MEM:UPD LIM saves limits
for voltage and current and the maximum allowable protection values for voltage and current.
MEM:UPD CONT saves the display contrast and background settings for the next power-up cycle.
MEM:UPD OUTP saves the load type defined by OUTP:MODE (see PAR. B.25). Related commands:
SYST:COMM:GPIB:ADDR, SYST:LANG, SYST:SET, VOLT:LIM, CURR:LIM, CURR:PROT:LIM,
VOLT:PROT:LIM, OUTP:MODE. See PAR. 3.5.2.2 and Figure 3-19 for special programming consider-
ations.
B.21 OUTPut[:STATe] COMMAND
OUTP
Syntax: Short Form: OUTP[:STAT] <boolean> Long Form: OUTPut[:STATe] <boolean>
<boolean>=(0 or OFF, 1 or ON)
Description: Enables or disables the power supply output. The factory default for power-up is Local mode, the
output is on and the front panel controls affect the unit's operation; however note that the factory
default for power-up can be changed from the front panel (see PAR. 3.3.8). Upon entering Remote
mode, the output. status is not affected.
For passive loads, when OUTP OFF is executed, the programmed values of voltage and current
are saved, then voltage and current are programmed as follows: when the unit is operating as a volt-
age source, voltage is programmed to zero and current protect is programmed to a low value; when
operating as a current source, current is programmed to zero and voltage protect is programmed to a
low value. When OUTP ON is executed, the power supply output is restored to the previously saved
programmed values. The saved values of voltage and current can be viewed by VOLT? and CURR?
queries.
For active loads (inductive, capacitive, battery or other electronic loads) programming the appro-
priate settings for mode, voltage and current is recommended instead of using the OUTP OFF com-
mand. Follow the guidelines presented in Table 3-6 to understand how the unit responds to OUTP
OFF. Instead of using OUTP OFF, program the unit to current mode using the FUNC:MODE com-
mand, then program output current to zero. Related Commands: FUNC:MODE, OUTP?.
VOLT 5;CURR .5 Voltage/current setpoints set to 5 Volts/0.5 Amperes, respectively
curr:prot 1;:volt:prot 14 Current protect set to 1 Ampere. Voltage protect set to 14 Volts.
MODE VOLT;:outp on Causes the BOP/BIT to output 5 Volts at up to 1 Ampere
in voltage mode.
*SAV4 Saves the six values in location 4 of the SAV memory area.
FUNC:MODE CURR Causes the output to go to 0.5 Amperes. Assuming a load of
5 ohms, the voltage measured at the output will be 2.5 Volts.
MEM:LOC? 4 Unit returns VOLT,5,0.5,FIX,1,14,FIX,ON.
mem:Loc 10,VOLT,10,3,,4,5,,ON Causes the settings to be stored in location 10.
*RCL 10 Immediately sets the unit to voltage mode @ 10 Volts with current
protection of 4 Amperes with output on.
MODE CURR Would sets current level to 3 Amperes and Voltage protection to
5 volts.
