Turns on, selects, and configures a channel. The key is illuminated with the corre-
sponding channel color, if the channel is active.
The effect of the keypress depends on state of the channel:
●
If channel is off: Pressing the key turns on the channel and selects it.
●
If the channel is on, but not selected: Pressing the key selects the channel wave-
form.
●
If the waveform is selected: Pressing the key opens the "Vertical" dialog box for the
appropriate channel.
The vertical rotary knobs are focused on the selected waveform and they are illumina-
ted in the color of the selected waveform.
REF
Opens the "Reference" dialog box, where you can configure and display reference
waveforms. Press the button repeatedly to switch to the reference waveform to be con-
figured.
The vertical rotary knobs are focused on the selected reference waveform and they are
illuminated in the color of the selected waveform.
MATH
Opens the "Math" dialog box, where you can configure the calculation of new wave-
forms with various mathematic operations from other waveforms. Press the button
repeatedly to switch to the math waveform to be configured.
The vertical rotary knobs are focused on the selected math waveform and they are illu-
minated in the color of the selected waveform.
POSITION / OFFSET
The rotary knob changes the vertical position or the offset of the selected waveform.
The horizontal axis and the selected waveform are moved vertically. Press the knob to
toggle the setting, and turn clockwise to move the waveform up. The controlled param-
eter and its value are shown in the input box in the upper left corner of the screen.
●
Position indicates the vertical location in divisions.
●
Offset moves the vertical center of the selected channel to the offset value.
The knob lights up in the color of the selected waveform.
