Sweep Interval: Press the Sweep Interval submenu key and use the rotary

Record: When the Time Span is set to an interval other than Auto, the
spectrogram plots will be automatically saved when the waterfall display is
full by pressing the Record submenu key.
Recording Time: When Record is set to On, the Recording Time submenu
key is displayed. Press this submenu key to specify how long the instrument

the spectrogram display. Press the Time Cursor submenu key to turn on the

at the cursor position was taken is displayed at the top of the screen.
Reset/Restart Measurement: Pressing this key will clear the captured
spectrogram display and start a new series of measurements.
