Frequency, duty cycle and pulse width measurements
Powered by 2 AA batteries
Probe and lead set included
Current measurement via additional current clamp
The SPi Wireless Automotive Signal Processor connects completely wirelessly to the SPi handset and allows you to measure signals and voltages found on automotive systems within a vehicle. Plug in the SPi to the diagnostics connector in the car, select the Wireless Module function on the handset and press the power button on the Wireless Automotive Signal Processor, the Wireless module is automatically detected. Using the probes provided you can hook up the module to a sensor output or actuator input and see in real time what the signal is doing, this can then be compared with the signal that the ECU is reading or providing using the standard SPi diagnostics. This is all done using a wireless connection to the SPi handset (up to 50m range*), so there is no need to keep running backwards and forwards, needing another pair of hands, someone to help, or trailing wires half way around the vehicle, now you can sit in the car and use the diagnostic handset, whilst the Signal Processor is testing signals under the bonnet.
The Wireless Automotive Signal Processor is specially designed and protected to measure, automotive signals such as Voltage, Frequency, Duty Cycle (PWM), High & Low Pulse Widths (PWM), it can also work with a suitable current clamp!.
There is no need to connect extra power cables as the wireless module is completely battery powered, and has a low battery indication via the SPi. The wireless module is also user updatable via USB, so when new features come out there is an easy process to upgrade your module.
