UltraSoundGate 116 |
part # 31161
# 31162 | |
|
Compact ultrasound recording interface with a balanced analog input, peak level meter,
trigger button, acoustic monitoring output, rugged aluminium housing, USB 1.1 interface and water-proof transport case.
Thanks to its compact size and the integrated peak level meter, this unit is certainly suited for hand held use with laptops or UMPCs in the field.

Principle of the UltraSoundGate
116-200 recording system
|
What are the advantages of Avisoft-UltraSoundGate 116-200 over other bat detectors? |
- The increased dynamic range (16 bit A/D conversion instead of
8 or 12 bits) and the newly designed microphones enable
high-quality recordings with superior signal-to-noise ratios.
- The integrated peak level meter (consisting of 5 LED's) helps
adjusting the recording level appropriately (for preventing both
overload and too soft recordings).
- Unlimited continuous recording time (the only limitation is
the size of the computer harddisk).
- Realtime spectrogram display during recording (can also be
disabled).
- A TTL-compatible digital input allows to synchronize the sound
recordings with other signals (e.g. video).
- Acoustic monitoring either using the broad-band monitor output
on the USG device or the virtual bat detector mode in the
Avisoft-RECORDER software (heterodyning or aliasing technique).
- In contrast to other PCMCIA-based direct-sampling solutions,
the UltraSoundGate system is truly portable and well suited for
rough field use. There are no fragile or bulky components that
might prevent flawless field work.

What is the advantage of the Avisoft Bioacoustics CM16/CMPA microphone over a 1/4" measurement microphone? |
The reliable analysis of soft ultrasonic vocalizations requires sound recordings that exhibit a good signal-to-noise ratio. 1/4" measurement microphones have been optimized for precision, durability and high-level applications.
As a result, the inherent noise level of such microphones is relatively high at about 30dB (re 20µPa). The CM16/CMPA microphone that is supplied with the ultrasound recording kit, provides a inherent noise level that is about 12 dB below that of 1/4" microphones:
The significantly lower noise floor certainly simplifies the subsequent automated analysis of the recordings.
