Avisoft UltraSoundGate Series User Manual

Introduction
Thank you for purchasing Avisoft UltraSoundGate 116Hbm. This
bus-powered USB device supports single-channel high-speed data
acquisition at sampling rates of up to 300 kHz.
The accompanying recording software Avisoft-RECORDER USGH
provides either continuous or triggered direct-to-disk recording with
real-time spectrogram displays.
Installation procedure
First install the RECORDER USGH software from the supplied
software installation media. The installation procedure will require
administrator rights. Check the option "RECORDER USG/USGH for
the Avisoft UltraSoundGate hardware" on the Software Component
Selection panel:
At the same time, the required device drivers (usgh_xx16h.inf,
usgh.sys) for the UltraSoundGate XX16H devices will be installed.
When the installation procedure has completed, the
UltraSoundGate unit can be connected to the computer. The device
should then be detected as "Avisoft-UltraSoundGate 116H" and the
pre-installed driver should be installed. Under some circumstances
(on Windows XP) it might happen that the Windows Device
Manager asks for the device driver file usgh.sys, which can be
found at C:/Program Files/Avisoft Bioacoustics/Drivers.The green
POWER LED (4) should light permanently and the amber REC LED
(3) should be flashing.
Getting started
The supplied RECORDER USGH software can be launched from
Start / All Programs / Avisoft Bioacoustics / RECORDER USGH
On the first program start, the configuration dialog box will be
launched automatically (otherwise it is available from Options /
Configuration). Select the desired Sampling rate from the Input
Device Settings section and click at Ok. Then click at the Pause
button (Monitoring/Pause) and the Start button (Monitoring/Start).
You will then see the real-time spectrogram displaying the incoming
signals. For details on the operation of the RECORDER software
see the Avisoft-RECORDER manual and the section RECORDER
USGH Software Settings in this guide.
