11.7. Common Commands

Common commands were first defined in the IEEE-488.2 standard, which is the predecessor of the SCPI
standard. They are not specific to power supplies. They are common commands which are useful for any
remote communication
Many common commands refer to bit-mapped registers in which setting bits to "1" or "0" indicates an
operating mode or fault condition. These are described in the Error and Status section 11.8 below.
11.7.1. Identity Query
This is a request for the power supply to identify itself. It is used by the remote computer to verify the
correct instrument is being communicated to and to determine the model ratings of the power supply.

11.7.2. Reset the Power Supply
This command will reset all settings in the power supply to a known, safe state. This includes setting the
programming limits to zero, output off, and auto-restart off. Other protections are disabled. Sending *RST
is the same as sending all nine of the following.
commands:
:VOLT 0
OUTP:STAT 0
OUTP:PON OFF
:VOLT:LIM:LOW 0

11.7.3. Save All Settings
This saves the present power supply settings. This is used along with the
which allows you to bring the power supply back to some setup configuration with only one command.
When the supply is powered-down, the

will program the voltage limit to 25 volts
DIAG:COMM:PASS PV 25
will be returned by the above command,
OK
(or an error such as E01 may be returned)
will measure the output voltage
DIAG:COMM:PASS MV?

Four fields separated by commas:
Field 1: Manufacturer name
Example: LAMBDA
Field 2: Model name, GEN<Volt rating>–<Curr rating>–Option
