Polarization Voltage Calibration Unit

Type 5008 is a high-impedance differential DC buffer intended to act as a buffer for high-impedance microphone polarization voltage, allowing the microphone polarization voltage to be measured using a common DC voltmeter.

USE SCENARIOS

For measuring 0V or 200V Polarization Voltage:

• At the input of a measuring instrument
• At the input of a microphone amplifier

The polarization voltage can either be measured in a 7-pin preamplifier socket or direct at the input terminal of a preamplifier.
