Instrument State Storage
Usage:
• All L4400 Series Instruments
The L4400 series instruments have five storage locations in non- volatile
memory numbered 1 through 5 to store instrument states. A sixth location
stores the instrument’s power down state which is restored when the
instrument is turned back on. You can assign a user- defined name to each of
locations 1 through 5.
• You can store the instrument state in any of the four locations, but you can
only recall a state from a location that contains a previously
stored state.
• When shipped from the factory, storage locations 1 through 5 are empty.
In addition, the automatic recall mode is disabled
(
MEMory:STATe:RECall:AUTO OFF command) and a Factory Reset (*RST
command) is issued when power is turned on.
• You can name a storage location, but the location is recalled using the
location number. The name can contain up to 12 characters. The first
character must be a letter (A- Z), but the remaining 11 characters can be
letters, numbers (0- 9), or the underscore character (“_”). Blank spaces are
not allowed.
• A Factory 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 following commands are used to store and recall instrument states.
*SAV {1|2|3|4|5}
*RCL {1|2|3|4|5}
To configure the instrument to automatically recall location 2 when power is
restored, send the following commands.
*SAV 2
MEM:STATE:RECALL:SELECT 2
MEM:STATE:RECALL:AUTO ON
