Orientation Connecting Signals and Selecting the Analysis Channel
Connecting Signals and Selecting the Analysis Channel
SignalVu analyzes signals acquired by the oscilloscope. The SignalVu software analyzes one, two, or
four signals at a time, so you need to specify which oscilloscope input channels to use. Math and Ref
channels can
To specify which oscilloscope channel is analyzed:
1. Select Settings > Acquire to display the Acquire control panel.
2. Select the desired signal type from the Signal Input drop-down list along the left side of the control
panel. Available choices are RF (uses one oscilloscope channel), IQ (uses two channels), and Diff IQ
(uses four channels).
3. On the Ver t ic a l tab, use the Source drop-down list(s) to select the channels to analyze.
4. Use the oscilloscope controls in the TekScope application to achieve a stable, triggered signal.
For information on the oscilloscope input signal capabilities and how to trigger on a signal, see the
oscilloscope's help. Note that SignalVu does not control triggering on the oscilloscope; you will need to
use the oscilloscope triggering functions to achieve a stable, triggered signal on the oscilloscope.

Front-Panel Controls
The front-panel controls remain dedicated to oscilloscope control functions when SignalVu is running. The
front-panel buttons and knobs of the oscilloscope do not have any effect on the SignalVu software settings.
NOTE. One button that affects the SignalVu software is the Run/Stop button. Pressing the Stop button

span about the point of interest. Span Zoom adjusts the span
control and can affect the acquisition bandwidth.
Adjusts horizontal and vertical scale of the graph. The first
direction with enough movement becomes the primary scale of
adjustment. Adjustment in the secondary direction does not occur
until a threshold of 30 pixels of movement is crossed.
Dragging to the left or down zooms out and displays a smaller
waveform (increases the scale value). Dragging to the right or up
zooms in and displays a larger waveform (decreases the scale
value).
Adjusts horizontal and vertical position of the waveform. The first
