STATe:RECall:AUTO?

•Any arbitrary waveforms downloaded to VOLATILE memory are not "remembered". However, if an arbitrary waveform is being output from NON-VOLATILE memory when the state is stored, that waveform is output when the state is recalled.

Usage <set up the desired instrument state>

MEM:STAT:REC:AUTO ON *SAV 0

<*RCL 0 automatically done at power up>

MEM:STAT:REC:AUTO OFF *SAV 0

MEMory:STATe:RECall:AUTO? Queries the current setting of the "auto-recall" mode.
