MEM:STAT:VAL? 3
User-Defined Power-On States
The 53220A/53230A counter can be set to power-up from one of five saved
state locations or from a state file (Figure 7-2). For this to occur:
1. the state must currently be saved
2. recall must be enabled
3. the state location or file name must be selected
This sequence is provided by the following commands:
//save state in instrument state locations 0-4
*SAV {0|1|2|3|4}
or
//store state in state file (.sta) - internal or USB
MMEMory:STORe:STATe <“file”>
//enable automatic recall at power-on
MEMory:STATe:RECall:AUTO {ON|OFF}
MEMory:STATe:RECall:AUTO? (query form)
//select the state location or file recalled at power-on
MEMory:STATe:RECall:SELect {0|1|2|3|4|<file>}
MEMory:STATe:RECall:SELect? (query form)
If automatic recall is enabled and a state location or file name is not selected,
the counter will power-on in the state it was in when last turned off
(location 0).
Following are examples of a state recalled from a numbered state location and
from a state file in internal flash memory.
