If the instrument is in the Stop mode, the measurement data buffers are
cleared and the waveform display is blanked. Data capture will resume
when >Measurement> Run is initiated.

When in the Modulated mode or the Pulse mode, use the >Display >
menu key to clear the averaging filters. This removes the effect of old
data on the trace, allowing newly acquired data to dominate.

When in the Stat mode, use the >Display> CLEAR key to discard the
histogram data and begin a new histogram. The total time and the total
points counters are also cleared.

A short cut to using the Esc key to return to the top level menu to get to
the >Display> CLEAR the Shift key followed by the Clr key clears the
display from any menu level.

Pulse, Modulated, Statistical

Pressing the measurement mode menu key, >Measure Mode>, switches
the instrument between the Pulse mode, the Modulated mode and the
Statistical modes. This change affects the entire instrument. The
measurement capture, processing , channel selection, data displays and
menu structure all change.


In the Pulse mode the instrument operates as a peak power
meter. This mode requires a valid trigger event. Instantaneous
power measurements are taken at random intervals and are
resolved in time relative to the trigger event. The instrument
reconstructs the waveform from points that fall within the
display‘s time window. This window is defined by the
timebase and trigger delay. Markers return measurements of
power at specific time offsets from the trigger point. All
automatic measurements are limited to the instrument‘s time
window.
