Equivalent Electrical Impedance Adapter Options
Choose one of the following adapters in place of the microphone when making very high impedance
measurements. The adapter acts as a series capacitor with the same capacitance as the microphone it
replaces. If you're making a square wave pulse measurement, include a 100 kHz, low pass, T filter with the
adapter.
