Using Masks, Histograms, and Waveform Databases
CSA8000B & TDS8000B User Manual 3- 151
Mask-counting statistics are displayed in the mask readout at the right-side of the
display. Mask counting statistics are displayed as soon as you enable a mask, and
stay visible even if the mask isn’t displayed on screen.
Mask number and hits count
Total number of hits in all masks
Total number of waveforms for all masks
If mask counting is enabled, read the results as follows:
H Mask (n): Each mask in the standard is listed by number (Mask 1 for
example) along side the number of hits in that mask.
H Total: Displays the total of all hits in all masks.
H #Wfms: Displays the number of waveforms that have been tested against the
masks.
To zero the counts for all masks, click Clear in the Mask Setup dialog box.
NOTE. Executing Clear will clear not only the mask counts, but also the
underlying waveform data. For example, if mask testing on a waveform database
the database data is cleared and accumulation is restarted, and if mask testing
on a waveform being averaged or enveloped, Clear restarts the averaging or
enveloping.
