COMMAND NAME
DESCRIPTION
Reset
Save
Service
Request
Enable
Service Request
Enable Query
Read Status Byte
Device Trigger
Self-Test Query
Wait-to-continue
8099 restores its power-up state except that
the state of IEEE-488 interface is unchanged,
including: instrument address, Status Byte
and ESR Register. Disables the trigger
function and pulses the Reset output signal.
Allow the 8099 100 ms and the 2303 150 ms
to complete the *RST command.
Saves current 8099 configuration in the F
l
ash.
*SAV 0 saves the current setting as the new
power on setting. <value>=0
Sets the "Service Request Enable Register"
to <value>. The value of bit six is ignored
because it is not used by the Service Request
Enable Register. <value> is an integer be-
tween 0 and 255, whose binary equivalent
corresponds to the state (1 or 0) of bits in
the register. If <value> is not between 0 and
255, an Execution Error is generated.
8099 returns the <value> of the "Service
Request Enable Register" (with bit six set
to zero). <value> is an integer whose binary
equivalent corresponds to the state (1 or 0)
of bits in the register.
8099 returns the <value> of the "Status Byte"
with bit six as the "Master Summary" bit.
<value> is an integer whose binary equiva-
lent corresponds to the state (1 or 0) of bits
in the register.
Pulses the Trigger Output line.
Queries the results of the last self test. A
zero response indicates no failures. Other
responses are not returned as the unit will
be running in a blink LED loop and will be
unable to respond to the query.
Prevents the 8099 from executing any further
commands or queries until the No-Opera-
tion-Pending flag is TRUE.
