Cx (Channel) Dialog
Full vertical setup is done on the Cx dialog. To access it, choose Vertical > Channel <#> Setup from
the menu bar, or touch the Channel descriptor box.
The Cx dialog contains:
Vertical settings for scale, offset, coupling, bandwidth, and probe attenuation
l
Current Bandwidth and Resolution when operating in HD Mode
l
Rescale settings
l
Pre-processing settings for pre-acquisition processes such as noise filtering and interpolation.
l
If a Teledyne LeCroy probe is connected to the channel, a
Cx dialog.
Vertical Settings
The Trace On checkbox turns on/off the channel trace.
Vertical Scale sets the gain (sensitivity) in the selected Vertical units, Volts by default. Select
Variable Gain for fine adjustment or leave the checkbox clear for fixed 1, 2, 5, 10-step adjustments.
Offset adds a defined value of DC offset to the signal as acquired by the input channel. This may be
helpful in order to display a signal on the grid while maximizing the vertical height (or gain) of the
signal. A negative value of offset will "subtract" a DC voltage value from the acquired signal (and
move the trace down on the grid") whereas a positive value will do the opposite. Touch Zero Offset to
return to zero.
A variety of Bandwidth filters are available at fixed settings. To limit bandwidth, select a filter from
this field.
Coupling may be set to DC 50 Ω, DC1M, AC1M or GROUND.
Caution: The maximum input voltage depends on the input used. Limits are displayed on the
body of the instrument. Whenever the voltage exceeds this limit, the coupling mode
automatically switches to GROUND. You then have to manually reset the coupling to its
previous state. While the unit does provide this protection, damage can still occur if extreme
voltages are applied.
