A.9
*OPT? — OPTIONS QUERY
Syntax:
*OPT?
Returns string determined by power supply model.
Description: Causes the power supply to return an ASCII string which defines the functionality of the power
supply. The functionality is defined as follows:
STRING DATA
CCAL
RL1
MEMM
LSTAPL
A.10 *RCL — RECALL COMMAND
Syntax:
*RCL <integer> (1 to 99)
Description: Restores power supply to previously defined levels of output voltage, output current and trig-
gers. This command selects one of the 99 power supply memory locations, each of which stores val-
ues for output current and output voltage. Executing a *RCL recalls the stored settings (see *SAV,
PAR. A.12, for details) from the specified location (whether stored locally or using SCPI commands)
and applies them to the unit.
A.11 *RST — RESET COMMAND
Syntax:
*RST
Description: Resets power supply to the power on default state. The power supply output set to power-on
default state (see PAR. 3.3.7): fixed voltage mode, 0 volts, current protect at minimum (box) value and
TRIG:SOUR to IMM. The factory default setting also insures the output is in the off condition. Other
commands such as *CLS are affected by *RST. The specific commands that are affected and what
occurs are explained in PAR. 3.5.3.1.3 and Table 3-17. After sending *RST it is necessary to send
OUTPut ON for programmed values to appear at the output.
A.12 *SAV — SAVE COMMAND
Syntax:
*SAV <integer> (1 to 99)
Description: Saves the present state of output voltage and output current to the specified memory location.
This command stores the present state of the power supply to one of 99 memory locations in Flash
Memory (see PAR. 3.6.3.7). The following parameters are stored by *SAV: FUNC:MODE,
VOLT:MODE, CURR:MODE, VOLT:PROT, and CURR:PROT. Settings stored are:
•
Mode of operation (Voltage, Current or External) FUNC:MODE < >
•
Main channel reference type (internal or external) and setting (if internal)
VOLT:MODE < > or CURR:MODE < >, VOLT < > or CURR < >
•
Protection channel reference type (internal or external) and setting (if internal)
VOLT:PROT:MODE < > or CURR:PROT:MODE < >, VOLT:PROT < > or CURR:PROT < >
•
Output status (on or off) OUTP < >
The stored values can be restored by the *RCL command. See PAR. 3.5.2.2 and Figure 3-16 for spe-
cial programming considerations.
A-4
Support for limit calibrations is present.
