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 Ve r tic 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.

Adjusts horizontal and vertical scale of the graph. The rst 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 rst direction with enough movement becomes the primary direction of movement. Movement in the secondary direction does not occur until a threshold of 30 pixels of movement is crossed.
Returns the horizontal and vertical scale and position settings to their default values.
Moves the selected marker to the highest peak. If no marker is turned on, this control automatically adds a marker.

To use the Modulation Analysis preset (assuming the Preset action is set to Show list in the Presets tab of the Options control panel):
1. Select Presets > Application. Select Modulation Analysis andthenclickOK.
2. Set the measurement frequency.
3. Set the reference level so that the peak of your signal is about 10 dB below the top of the spectrum

You can make a selected pulse and measurement appear in the Pulse Trace display by highlighting it in the Pulse M easurement Table. Key pulse-related parameters that are set by the Pulse Analysis application preset are:
Measurement Filter: No Filter.
Measurement Bandwidth: This is set to the maximum real-time bandwidth of the instrument. Note: The label on the “Measurement Bandwidth” setting is just “Bandwidth”. Like the main instrument Preset command and the other application presets, the Pulse Analysis application preset also sets most other instrument controls to default values.
Analysis Period: This is set to 2 ms to ensure a good probability of catching several pulses for typical signals.

You may need to trigger on the signal to get a more stable display. This is set up with the oscilloscope's controls. A rising-edge trigger works well for many pulsed signals.

3. Set the Reference Level to place the peak of the signal approximately 0-10 dB down from the top of the Spectrum graph.
4. If the signal is transient in nature, you might need to set a trigger to capture it. You will need to use the oscilloscope triggering functions to capture the signal.
When the signal has been captured, the spectrogram shows an overview of frequency and amplitude changes over time. To see frequency transients in greater detail, use the Frequency vs. Time display.
The Time-Frequency Analysis preset sets the analysis period to 5 ms. The Spectrum Span is 40 MHz. The RBW automatically selected for this Span is 300 kHz. For a 300 kHz RBW, the amount of data needed for a single sp each one forming one trace for the Spectrogram to display as horizontal colored lines. This preset scales the Spectrogram time axis (vertical axis) to -2, which means that the Spectrogram has done two levels of time compression, resulting in one visible line for each four transforms.
