| The condenser microphone Avisoft Bioacoustics CM16/CMPA provides a good compromise between
sensitivity and flatness of the frequency response. It consists of
an externally polarized metalized film diaphragm and a metal
back plate. The capsule is replaceable in order to handle the
relatively low durability of the thin diaphragm. This microphone model requires an additional 200V polarization voltage that is supplied by the UltaSoundGate base units. An optional USB-powered heating module can prevent condensation when the microphone is being used in the field.

functional principle

* The E- and M-series NI DAQ devices and other budget data acquisition systems do not include an anti-aliasing filter.
However, the lack of such a filter can seriously degrade the overall signal-to-noise ratio of the recording system because noise components at frequencies above the nyquist frequency will be folded down to lower frequencies.
For best results, it is therefore recommended to use an additional anti-aliasing filter (part#40026) or one of the UltraSoundGate xx16x devices that come with an integrated adaptive AAF.
Setting up an (ultrasound) recording system with third-party DAQ devices such as National Instruments units is not always simple because there are many potential pitfalls. We therefore recommend to use the integrated UltraSoundGate systems instead.
