:SERial[n]:STORe

Until
…
STORe is executed, communication parameter values are stored
in volatile memory, and a power failure will cause the settings to be lost.

DIAG:COMM:SER(1-7):STOR causes an Agilent E1324A (B-size
RS-232 card) to store its settings in an on-board EEROM. This EEROM
write cycle takes nearly one second to complete. Wait for this operation
to complete before attempting to use that serial interface.
•
The Agilent E1324A’s EEROM used to store its serial communication
settings has a finite lifetime of approximately ten thousand write cycles.
Even if your application program sent the
…
STORe command once
every day, the lifetime of the EEROM would still be over 27 years.
Be careful that your application program sends the
…
STORe command
to an Agilent E1324A no more often than is necessary.
