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.
