Description

Attenuator 10:1 with High Bandwidth

With high bandwidth and fault-protection, the 10:1 attenuator has been designed to allow fuel injector and primary ignition waveforms to be measured using PicoScope oscilloscopes.

The TA197 is a passive 10:1 attenuator. This means that a 10V signal at its input will appear as a 1V signal on the output.
The TA197 allows voltages of up to 400V to be measured.

The TA197 attenuator also increases the input impedance of the oscilloscope from 1 MOhm to 8 MOhm and can also be used when measuring the output of high-impedance sensors such as piezo knock sensors where directly connecting an automotive scope can attenuate the signal or induce a fault code.

Please note: When using a PicoScope 4225 or 4425 oscilloscope the attenuator is not normally needed for measuring injectors as the voltage spike is usually under 200V.  It will be required however when using older generations of PicoScopes which only measure to 50V or 100V.  
The 10:1 attenuator is an improved version of the 20:1 attenuator previously available from Pico.
