Using The Enhanced Monitoring System 4-45
*SAV Command
The *SAV command will store the present instrument state into
nonvolatile memory. The *SAV command may specify a
nonvolatile memory location into which the instrument state is
saved. That is, both of the following formats are accepted:
*SAV
*SAV
<location>
If <location> is specified, it must be in the range 0 to 9. If
<location> is not specified, the instrument state will be saved into
nonvolatile memory location 1. Note that *SAV location 0 is
recalled at power-up if the DIP switch SW1-8 is set.
The *SAV command saves all of the attributes described in the
*RCL command description into the specified nonvolatile
memory location.
*TRG Command
The *TRG command is required by the IEEE-488.2 specification.
This command is accepted but has no effect on the EMS.
*WAI Command
The *WAI command is required by the IEEE-488.2 specification.

Performing The
Self Test
The EMS performs a series of self-tests when power is first
applied. If any of the self-tests fail, the following message is
displayed on the 10 character LED display on the front of the VXI
mainframe:
Self Test Failed!
To determine the cause of this failure, perform one of the
following 3 operations:
C
Connect an RS-232 terminal to the RS-232 port of the
EMS. Cycle power to the EMS by removing and
reconnecting the AC power cord. Observe the error
messages displayed on the terminal to determine which
of
the self-tests have failed.
C
Connect an RS-232 terminal and keyboard to the RS-232
port of the EMS. Type the command
SYST:ERR?
on the keyboard. Observe the reply to determine the cause
