This accessory makes an externally polarized 1/4" microphone cartridge (typically a G.R.A.S. 40BP) behave like an electrostatic loudspeaker which, in a coupler, has a frequency response as good as when used as a microphone. It takes a calibration signal directly from a signal generator. The G.R.A.S. RA0086 has a Microdot connector.
