The "lU"
command
interrogates the
Generator
for the
UNCAL
entry
status.
(See Table
2-5 for
a
list
of the
UNCAL
Error Codes.)
The
"IV"
command
interrogates the
Generator
for
its
current
software
revision
level.
The
returned record
is
similar to the following:
"VI.O"
(EOR>.
This
means
that the
software
revision
level
is
Version
l.O.
The
"IZ"
command
interrogates the
Generator
for the
compensation
memory
status.
The
status
is
returned
as three
fields
similar
separated
by
commas,
to the following:
"000010,100001,000000"
<EOR)
See
the
paragraphs
on Compensation

MONITOR
COMMANDS
The
Generator monitor
commands
are
intended
for
troubleshooting
and maintenance
procedures.
They
allow
the
instrument
hardware
to
be
programmed
to states
not normally
possible
with
the regular
programming commands.
CAUTION
The
output
of
the
Generator
Is
not
guaranteed
If
the
Generator hardware has
been changed
with
these monitor
commands.
There
are three
types of
monitor
commands:
Input/Output,
Read/Write, and Hardware
Control. Table 2-15
lists
the
Input/
Output
types of
monitor
commands.
Table 2-16
lists
the
Read/Write
types of
monitor
commands.
Table
2-17
lists
the
Hardware
Control
types of
monitor
commands.
2-60.
SRQ
COMMANDS
The
Generator
asserts the
SRQ
bus
management
line
on
the
IEEE-488
Interface
bus whenever
the
Generator
requires
service.
The
controller
can then perform a
serial
poll to
determine
the
need
for
service.
The
set
mask
command
is
used
to
designate those
needs
that require
service.
The
SRQ
commands
are as follows:
"SM"
Set
SRQ
Mask
"IM"
Interrogate
SRQ
Mask
"XF"
