This versatile PWM detector measures pulse width and frequency precisely and updates instantly for quick analysis. You can switch easily between the pulse width and frequency displays to diagnose issues.
Its measurement range is 50 to 9950 microseconds, which covers common remote-control signals (1000-2000us) and robotic applications (500-2500us). Standalone seesaw testing lets you calibrate remote controls independently.
A 'NO' signal indicator (after 70 seconds of signal loss) and reverse-polarity protection ('+' and '-') make operation reliable and user-friendly.
Compact, high-performance tester: small enough for a toolbox.
Universal compatibility: RC servos, ESC signals and flight controller outputs.
Precision diagnostics: pulse width and frequency readings.
Wide measurement range: 50 to 9950us.
Standalone seesaw testing: calibrate remotes on their own.
Protection: NO-signal indicator and reverse-polarity protection.
Most RC receivers, ESCs and servos communicate using pulse width modulation: a short pulse repeated at a fixed rate, where the length of the pulse encodes the command. Servos treat about 1500 microseconds as centre, with 1000 and 2000 microseconds at the ends of travel.
A PWM tester plugged into a receiver channel or flight controller output shows the pulse width, so you can check that your transmitter's endpoints, trims and failsafe values are what you expect. It also shows the frequency so you can confirm the output rate.
If a servo jitters, an ESC will not arm or a receiver channel seems off, a tester quickly shows whether the signal itself is wrong or whether the problem is in the device receiving it.
