Frequency counter doesn't power on and reveals no indication of inner voltage existence. Teardown of the tool shows a huge PCB where all digital and analog circuity is included. The power distribution module is a module parts and upon dimensions shows no action.

Its specifications must be four times greater than the specification of this DMM Digital Multimeter it's analyzing.

The easiest method is to exploit the headset jack that's currently present on the telephone! Now like every technology job there are limits about the requirements of exactly what this port can perform.

The instrumentation needed to develop and test today’s technologies has grown into many signal generator types over the years.

AWG Block Diagram Arbitrary waveform generators (AWG's) are electronic signal sources that function very similar to a digitizer in reverse. Selected samples of the waveform are sent into a digital to analog converter (DAC) and subsequently, with proper filtering and signal conditioning, are output as an analog waveform.

The Universal Frequency Counter symptom is that just station C appears to operate properly and channel A or channel B generates any dimensions.
