• To create a new parallel bus, tap the Math Ref Bus > Add New Bus button on the Settings bar
. Open the bus configuration menu by
double clicking on the badge. Set the Bus Type to Parallel.
• To change the settings on an existing parallel bus waveform, double-tap the Bus waveform badge to open the configuration menu, and
make necessary changes.
Parallel bus configuration menu fields and controls
Field or control Description
Display Turns On or Off displaying the bus on 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 the 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 Parallel to define a parallel bus.
Clocked Data Toggles Yes or No to use a clock signal to recover the data bits from the bus inputs.
Clock Source Sets the source for the bus clock signal. The source can be an analog or digital channel.
Available when Clocked Data is set to Yes.
Polarity Sets the clock signal edge to use for timing reference.
Available when Clocked Data is set to Yes.
Threshold Sets the threshold value to determine high logic value.
Available when Clocked Data is set to Yes.
Define Inputs Opens a Parallel Bus - Define Inputs configuration menu to set the signal sources and the bit order
(MSB to LSB) for the bus. See Parallel Bus - Define Inputs menu on page 129.
Display Format Sets the waveform view to show just the decoded bus information, or the decoded bus plus the source
signal waveforms.
Decode Format Sets the decode format used to display the bus information. Formats are Hex and Binary.
Other bus types
Other serial bus types are available as purchasable options. Once purchased and installed, the new bus types are shown in the Bus
T
ype menu. The serial bus options also add corresponding bus trigger capabilities (when supported) to the Trigger menu. See the Bus
configuration menu on page 127 for links to all serial bus configuration menus.
