PWM (Pulse Width Modulation)
PWM (Pulse Width Modulation) Protocol Analyzer settings: analyze up to 6 pulse channels, optionally with a direction channel for forward/reverse; plot Duty, Frequency, or RPM. For Channel UI differences by product family, see Settings.

Settings
- Settings:
- PWM #1–#6: Enable PWM channels to analyze (up to 6). Clearing a lower number also disables (Disable) higher numbers. Default: only PWM #1 enabled.
- Pulse channel: LA channel for that PWM pulse. Default: LA-0 / LA-2 / LA-4 / LA-6 / LA-8 / LA-10 by index.
- Direction channel: Optional direction signal. When checked, the channel and Direction message are enabled (Enable); when cleared they are disabled (Disable). Default: cleared.
- Direction message: High(1): Positive / Low(0): Positive — which level means forward. Editable only when Direction channel is checked. Default: High(1): Positive.
- Time(X)-Duty(Y) / Time(X)-Freq.(Y) / Time(X)-RPM(Y): Y-axis of the decoded plot. Duty = duty cycle; Freq. = frequency; RPM = revolutions. Choose one. Default: Time(X)-Duty(Y).
- Sample Rate: PWM analysis sample rate (50 KHz–200 MHz). Too low can skew measurements. Main Default does not reset this field; new protocol defaults to 1MHz.
