Has anyone ever tried measuring a Car Radio Antenna Signal before?
I have a car with a complaint of poor radio reception on AM. Another Dealer and Ourselves have looked at this car multiple times and the process the Radio, the Antenna base and the Antenna Amplifier Module have all been replaced. The Radio Ground and Co-Axial Ground have been checked numerous times, along with the Co-Axial signal wire and always test Ok.
There's no BUS Communication with this Radio Head Unit, so we can't check signal strength that way, even supposing it had that capability if we did have CAN Comms.
So I'm thinking I'd like to check the RF signal with the Pico Scope. Check the Signal at opposite ends of the Antenna Cable and check for an amplitude loss or maybe a invasive signal from somewhere else on the car.
It's a measurement I've never tried before, so I'm unsure if the Pico Auto software will do the job, is there any special setting I need to configure etc., etc.
