ESO-20/40: For Ground Reference and Supply Offset Testing

ESO-20 & ESO-40 cable

The AE Techron ESO-20/40 cable was designed for use in ground reference and supply offset testing as required by ISO 16750-2 Section 4.8 and other similar automotive EMC standards.

The ESO-20/40 cable can be used to connect from the AE Techron 3110A's balanced output to the balanced input of an AE Techron 7000 series amplifier.

The ESO-20/40 cable extends the common-mode rejection of AE Techron amplifiers, allowing the amplifier negative output terminal to be raised above ground by up to 40V (meeting requirements for systems up to 24V).

When in use, the ESO-20/40 cable will reduce the amplifier's gain and increase output voltage accuracy for all standards. The ESO-20/40 cable must be used with an AE Techron 3110A Standards Waveform Generator and can be paired with any AE Techron amplifier via its balanced signal input connection.
