LeCroy WaveRunner XI Series User Manual

OPERATOR’S MANUAL
Bandwidth Limit
Reducing the bandwidth also reduces the signal and system noise, and prevents high frequency aliasing.
Bandwidth Limiting Setup
To set bandwidth limiting:
1. In the menu bar, touch Vertical, then select a channel from the drop-down menu.
2. Touch inside the Bandwidth field and select a bandwidth limit value from the pop-up menu.
The options are:
o Full
o 200 MHz
o 20 MHz
Averaging
The WaveRunner Xi oscilloscope allows you the opportunity to continuously average your signal to reduce signal
noise and aid in signal evaluation. If you want to use averaging, select a value here by touching inside the
Averaging field and entering a value up to 1 million sweeps on the pop-up keypad.
Linear and (SinX)/X Interpolation
Linear interpolation, which inserts a straight line between sample point, is best used to reconstruct straight-edged
signals such as square waves. (Sinx)/x interpolation, on the other hand, is suitable for reconstructing curved or
irregular waveshapes, especially when the sample rate is 3 to 5 times the system bandwidth.
Interpolation Setup
1. Touch the button for the channel you want to set up, for example.
2. In the dialog area, touch inside the Interpolation field under Pre-Processing. "Pre-Processing" means
before Math processing.
3. Touch inside the Interpolation field. A pop-up menu appears offering Linear or Sinx/x interpolation.
4. Touch the button for the type of interpolation you want.
Inverting Waveforms
Touch the Invert checkbox to invert the waveform for the selected channel.
QuickZoom
QuickZoom automatically displays a zoom of the channel or trace on a new grid.
Turning On a Zoom
Touch the Zoom button in the Vertical Adjust dialog.
Finding Scale
You can access the Find Scale button from the Vertical Adjust dialog. This feature automatically calculates
peak-to-peak voltage, and chooses an appropriate Volts/Div scale to fully display the waveform.
Using Find Scale
1. Touch the trace label for the waveform you desire.
2. Touch the Find Scale icon.
