SENT serial bus configuration menu
Use the SENT bus menu to set up and display a SENT (Single Edge Nibble Transmission) serial bus waveform.
• To add a new SENT bus waveform
1. Tap Math Ref Bus > Add New Bus on the Settings bar.
2. Double-tap the new bus badge to open the bus configuration menu.
3. Set the Bus Type to SENT.
4. Use the menu fields and controls to configure the SENT bus parameters.
• Double-tap the Bus waveform badge to change the settings on an existing SENT serial bus waveform.
SENT serial bus menu fields and controls
Field or control Description
Display Turns On or Off displaying the bus in the W
aveform view.
Label Enter a label for the bus. The default label is the selected bus type.
To enter label text, double-tap the field and enter label using virtual keyboard, or tap the field and enter
text from an attached keyboard.
Position Sets the vertical position of the bus waveform. The default position is vertically centered in a slice (in
Stacked mode), or center screen in Overlay mode. The unit of position is screen divisions.
Set to 0 Sets the vertical position to 0 divisions (centered vertically in a slice or on the screen).
Results Table Sets the results table as On or Off to see the active measurements, bus decode activity, and search
results in a spreadsheet format. Default is off.
Bus Type Set to SENT to set up and display a SENT serial bus waveform.
Source Select the signal source from the listed analog and digital channels.
Threshold Sets the high/low logic transition level.
Polarity Sets the signal edge to use to determine the width of the clock tick pulse.
Normal (default) corresponds to a falling edge polarity that determines how many ticks wide a pulse is.
Inverted corresponds to a rising edge polarity.
Clock Tick Sets the time period of the clock tick. The valid range is from 1 µs to 300 µs. The default is 3 µs.
Tick Tolerance Sets the tolerance, as a percent, that is acceptable for the clock tick signal to be recognized. The valid
tolerance range is from 1% to 30%. The default tolerance is 20%.
Fast Data Channels Sets the number of fast data channels. The default is 2.
Data Nibbles Sets the number of data nibbles to detect in the serial signal (3, 4, or 6).
Available when Fast Data Channels is 1.
Channel Widths (C1/C2) Sets the number of bits per channel when using two fast data channels (12/12, 14/10, or 16/8).
Available when Fast Data Channels is 2.
Pause Pulse Sets the instrument to detect a Pause pulse in the serial data. The default value is Yes.
