Making Eyeline Measurements
(HP 83480A Option 001 only)
NOTE
It is usually easiest to congure the HP 83480-series digital communications analyzer in terms of time
base, color-graded display, mask test, and so forth, before executing the eyeline application.
Instrument setups can be changed while eyeline is running, but observe the
following:
 Ignore
the message
"keypress ignored,
the instrument
is
in
remote" that
shows up
when you
press a
key
.
The
instrument
is
in
remote
,
but it
is still
interpreting
keystrokes
.
This
is
an
instrument

limitation.

the
program
is
running,
you
can

the
