key. This

a
plot
of the sweep parameters

Press
the "ON/STANDBY"
key so that the
"ON" led is lit.
Then press
the
"SWEEP" key and
select {sweep ramp}

The

a few seconds
before the sweep/plot
starts
due to the
instrument’s own
integration delay,
plus the delay that
you entered in
the sweep
parameters.
When complete
the
SI1287
will
return to the "STANDBY"
mode
with the
respective
led lit. The plot
should resemble figure
