Please note the 2204A has an overvoltage range of 100 V. In addition the scope is also only 8-bit, samples at just 100 MS/s (one channel in use, or 50 MS/s 2 channels in use), and an 8 kS buffer memory.
To give something as reference, our latest automotive scope has:
400 MS/s (one channel in use, 200 MS/s 2 channels and 100 MS/s for 3/4 channels in use).
250 M samples buffer memory
250 V Overvoltage protection
+ of course it also works with PicoScope Automotive software (which includes all the Guided Tests and access to the Waveform Library).
Please also note the automotive software also references safety information regarding when attenuation should be used for measuring voltages on a vehicle (based on the scopes the software supports).
I understand there is a cost difference, but I wanted to highlight the above for anyone who comes across this thread.
