Acquire the Signal
Acquire a non-repetitive or a single-shot signal.
Use Average mode when you want to do the following:
Acquire a repetitive signal.
Noise on your signal is rand om (not correlated with the trigger).
Increase the vertical precision of your acquisition.
NOTE. You ca n use FilterVu with Bandwidth Limit. You cannot use FilterVu with Average mode.
Quick Tips
Youcanchoosetosavetoafile with full resolution (every point that was captured) or re duced resolution (fewer points). When
your signal is filtered, on ly the reduced-resolution waveform is guaranteed to be filtered to the chosen frequency. Sometimes,
the filter is unable to produce a full-resolution waveform with a frequency as low a s the chosen frequency. The frequency
of the full-resolution waveform is shown in the saved file.
When the glitch capture background is on, a sa ved waveform file includes both the foreground and the background data.
Reference waveforms can be filtered; the chosen noise filter frequen cy also applies to references. Reference w aveforms also
have a glitch capture background.
Reference waveforms are always saved at full resolution. Unlike saving a waveform to a file, there is no reduced resolution
option.
