# PlugIn "Time parameters" The PlugIn "Time parameters" allows the program to calculate and display duration, duty cycle and frequency of a signal. PlugIn "Time parameters", mode "pulse width". This PlugIn and mode allows the program to display in real time the pulse width of a signal, for example injector pulse width. PlugIn "Time parameters", mode "duty cycle and frequency". This PlugIn and mode allows the program to display the duty cycle and frequency of a repetitive signal in real time. When analyzing PWM (Pulse Width Modulation) signals it may be necessary to operate the vehicle in such a manner that the PWM is activated. One example would be the PWM solenoid for the TCC (Torque Converter Clutch) in the transmission. PlugIn "Time parameters" displays this information for the channel that the oscilloscope is set to trigger from.
