Pulse Analysis

The Pulse Analysis feature allows various calculation of various pulse characteristics to be made automatically. It is setup from the the "Setups\Signal Analysis" menu item, or the blue "SA" button.

Note: updated installs may not show the toolbar button. Select the small button on the "SS SO PO R G N..." toolbar and use the customize feature to add the button.

The "Calculate" button will only result in valid data if a simulation run has been made.

"Level" Parameters

Max level, mid level and min level parameters set the values that characterize the measurement. The max and min levels should be set to the top and bottom flat portions of the pulse waveforms, that is after any initial overshoots. The mid level should be set to a midpoint level in-between the max and min levels.

Rise/Fall times - Calculated from the 10% and 90% of the max and min levels. "Levels" may be offset if other values are desired for the rise/fall time calculations.

Pulse Position Count - Sets how many pulses (counts) are ignored from time t=0 before the measurement is made. Typically the first few pulses may not be in a steady state condition.

Pulse Polarity, sets whether the pulse is a positive pulse or a negative pulse for the pulse width calculation, and sets the edge used for the delay calculation.

Delay - Delay is the time delay from the measured signal to the reference signal.

"Display data in output window on run" - If this is enabled, repeated runs will will display the pulse analysis data in the main output status window bar.

The is also an option under the "View" menu to generate a Report from all runs of the pulse analysis data.

Examples

Open and run the AnalogJKDTest.sss or FiberOpticTxRx.sss schematics for illustrations of this feature.
