State Storage Commands
The power supply has five storage locations in non-volatile memory to store power
supply states. The locations are numbered 1 through 5. You can also assign a name
to each of the locations (1 through 5) for use from the front panel.
*SAV { 1 | 2 | 3 | 4 | 5 }
Store (Save) the present state of the power supply to the specified location. Any state
previously stored in the same location is overwritten (no error is generated).
• A power-on reset (*RST command) does not affect the configurations stored in
memory. Once a state is stored, it remains until it is overwritten or specifically
deleted.
• The state storage feature ‘‘remembers’’ the states or values of the following
commands:
CURR, CURR:STEP, CURR:TRIG, OUTP, OUTP:REL, TRIG:DEL,
TRIG:SOUR, VOLT, VOLT:STEP, VOLT:TRIG, VOLT:PROT,
VOLT:PROT:STAT, and VOLT:RANG
*RCL { 1 | 2 | 3 | 4 | 5 }
Recall the power supply state stored in the specified storage location. When shipped
from the factory, storage locations ‘‘1’’ through ‘‘5’’ are empty.
Note: DISP {OFF|ON} can be stored and recalled in remote interface mode only.
Going to local mode automatically sets the display state to ON.
MEMory:STATe
:NAME { 1 | 2 | 3 | 4 | 5} , <quoted name>
:NAME? { 1 | 2 | 3 | 4 | 5}
Assign a name to the specified storage location. From the remote interface, you can
only recall a stored state using a number (1 through 5). The :NAME? query returns a
quoted string containing the name currently assigned to the specified storage location.
If the specified location has no name assigned, an empty string (‘‘ ’’) is returned. The
name can contain up to 9 characters. The first character can be a alphanumeric. Blank
spaces are not allowed. An error is generated if you specify a name with more than 9
characters. See ‘‘State Storage’’, on page 60 for more information. An example is
shown below.
‘‘MEM:STATE:NAME 1,‘P15V_TEST’’’
If you do not specify a name (note that the name parameter is optional), no name is
assigned to that state. This provides a way to erase a name (however, the stored state
is not deleted).
