What's new?
The D1000X detector is now
available. The D1000X is our new professional bat detector with heterodyne,
frequency division and time expansion systems. It also has a built-in 16-bit
recording system using a Compact Flash card as storage medium, making it
possible to save the recordings without having to use a separate tape recorder.
The recording length is only limited by the available space on the CF card.
Using a separate ultrasound loudspeaker, it is also possible to replay the
ultrasonic signals with the D1000X.
The D240x
detector is based on the popular D240
model and has a number of new and very useful functions, such as
increased time expansion memory storage time (max 3.4 sec),
manual and level-sensitive triggering and replay of the memory
contents through the heterodyne system. Using an optional
interface box, it is also possible to make the D240x
automatically dump each time expanded sequence onto a connected
cassette tape recorder or computer.
Version 3.3 of the real-time spectrogram sound analysis software BatSound is now available. Version 3.3 includes the new Automatic Recording mode, in which it is possible to have the computer
record sounds automatically. The desired threshold level is selected and the
computer will start recording to a sound file as soon as the signal exceeds this
level. Many parameters are available to fine-tune this mode, e.g. by setting
limits for the minimum pulse length, total recording time, maximum number of
pulses to record etc. Frequency-selective triggering is also available, to avoid
recording undesired signals.
New since version 3.1 is also the "Pulse Characteristics Analysis" command. This allows automatic extraction of many important signal parameters, such as:

In
addition to all functions found in BatSound, BatSound Pro also supports direct recording and playback of ultrasonic signals at
sampling rates up to 500 kHz!. Using
one of the supported fast PCMCIA data acquisition cards on your
laptop, you can view the spectrograms in the field immediately
after making a recording. This system is also capable of
replaying the recorded signal at reduced speed, i.e. it will work
just like a time expansion bat detector.
