User’s Guide
4.3. Channel visibility controls
The channel visibility controls are located in the left of the main window.
Fig. 4.3.1. – Channel visibility controls
“A“ – activates/deactivates channel A waveform
“B“ – activates/deactivates channel B waveform
4.4. Display mode controls
The display mode controls are located in the left of the main window.
Fig. 4.4.1. – Display mode controls
“BF“ – activates/deactivates „Beam finder“ mode. When activated, the
waveform exceeding vertical range is displayed as line on appropriate side of the
screen.
“Line“ – activates/deactivates mode, where the sample is connected with
adjacent one with line.
“Rew” (Rewrite) and “Roll” control the waveform drawing mode. When
“Rew” is selected, the waveform is always drawn from the left to right side of the
screen and the old waveform is continuously cleared off. When “Roll” is selected, the
waveform is drawn always on the right edge of the screen and rolls to left.
TIP: The “Roll” mode requires more processor time. If you display waveform
sampled with high sampling rate, choose the “Rew” mode.
“Display” – switches on/off the oscilloscope screen
TIP: Switching off the oscilloscope screen lowers the possibility of data loss.
4.5. Data save controls
The data save controls are located in the bottom of the main window.
