performing a Level compensation procedure.
AQO
Hz Indicates that the internal modulating
frequency
is
400
Hz.
1000 Hz Indicates
that the internal
modulating frequency

FREQUENCY
DISPLAY
FIELD
A 9-digit display, with six indicators used
to
display
the output frequency of
the Generator. Also used to display
the special function code, status
error codes,
or
the
memory Location
being
stored or recalled, as
well
as
relative and actual frequency,
when REL
is
lit, and step
frequency.
STEP Indicates that the STEP C''] or Cv3 keys
(Step Entry)
affect the output frequency.
REL Indicates
that the displayed frequency is relative to a
reference
frequency.
COMP Indicates that the compensation memory
protection switch
on the A2 Controller PCA is set to the enabled
position.
FM Indicates that an FH
compensation procedure
is in
progress
OUT Indicates that an Output compensation procedure is in
progress
ATT Indicates that
an
Attenuator compensation procedure is in
progress.
®
AMPLITUDE
DISPLAY
FIELD
A 3
1/2-
(and sign) digit display,
with
six
indicators,
used to display the output amplitude
of the Generator
into a 50-ohm load.
STEP
Indicates
that the
STEP or
Cv3
keys (Step Entry)
affect the output amplitude.
REL Indicates that the
displayed amplitude is relative to a
reference
amplitude.
dBm Indicates that the output amplitude is in
decibels
relative to
one milliwatt.
V
Indicates that the output amplitude is in
volts.
uV Indicates
that the output amplitude is in
microvolts.
mV Indicates that
the
output
amplitude is
in
millivolts.
®
STATUS
DISPLAY
FIELD
The status display field
is
composed of
11 indicators
used to denote
the current status of the Generator or
instrument
entry.
EXT REF
Indicates that the rear panel REF
switch
is
in the EXT
(external)
position.
