make the changes permanent. Following this procedure will
put the settings into non-volatile memory and allow them to
be restored during instrument power-up.
Service Request
(SRQ)
The 1257 may generate a service request (SRQ) in response to a
variety of events. These events include detecting a programming
error or confidence mode failure, generating a response to a query,
and many others.
Consult the
IEEE-488. 2 Status Description
section in
Chapter 5,
SCPI Command BASICS
for a description of how to program the
1257 to generate a service request.
