How to set up the spectrum view

Creating a spectrum view

First, ensure that the trigger mode is not set to ETS , as it is not possible to open

a spectrum view in ETS trigger mode.

There are three ways to open a spectrum view :

Click the Spectrum Mode button in the Capture Setup toolbar . We recommend

using this method to get the best spectrum analysis performance from your scope.

Once in Spectrum Mode, you can still open a scope view to see your data in the

time domain, but PicoScope optimizes the settings for the spectrum view.

Go to the Views menu select Add view, then select Spectrum.

This method opens a spectrum view in the currently selected mode, whether this is

Scope Mode or Spectrum Mode. For best results, we recommend that you switch to

Spectrum Mode, as described in the method immediately above.

Right-click on any view , select Add view, then select Spectrum. The menu is

similar to the Views menu shown above.

Configuring the spectrum view

See Spectrum Settings dialog .

Selecting the source data

PicoScope can produce a spectrum view based on either live or stored data. If

PicoScope is running (the Start button is pressed in), the spectrum view represents

live data. Otherwise, with PicoScope stopped (the Stop button pressed in), the

view represents data stored in the currently selected page of the waveform buffer.

When PicoScope is stopped, you can use the buffer controls to scroll through the

buffer and the spectrum view will be recalculated from the waveform currently

selected.
