Introduction
Thank you for purchasing Avisoft UltraSoundGate 116Hb 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
Getting started
The supplied RECORDER USGH software can be launched from
Start / All Programs / Avisoft ioacoustics / 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

The 5-pole XLR input connector represents the analog inputs of the
recording device and provide power supply voltages for external
amplifiers and microphones The connector scheme is as follows:

3 PHONES
This stereo 3 5mm mini jack connector allows to connect
headphones or a small speaker for acoustically monitoring the
incoming ultrasounds A undersampling technique is being used
to convert the ultrasonic sounds into audible signals The
undersampling ratio can be adjusted from the Advanced USGH
Settings dialog box of the RECORDER USGH software (see
section RECORDER USGH Settings for details)
4 TRG button
This button can control the wav file recording process in the
RECORDER software To enable this mode of operation, one of
the following Trigger source options must be selected from the
configuration dialog box:
USG TRG button auto hold : Pressing the button for more than 2 seconds will
activate an auto hold mechanism (the recording continues after releasing the button and
will stop once the button is pressed again) If the button is pressed for less than two
seconds, it will only record as long as the button is being pressed
USG TRG button : The software will record as long as the button is pressed
USG TRG button inversed : The software will record as long as the button is not
pressed (or as long as the external TRG signal is not active (logic high))
USG TRG button toggled : The software will start recording once the button is
pressed and continues until the button is pressed again
5 REC indicator
This amber colored LED will flash once the device is connected to
the PC It will be switched off once the RECORDER USGH
software is running the in the monitoring mode In this mode, the
REC LED indicates whether the RECORDER software is recording
the incoming data onto disk
6 OVERload indicator
The red OVER LED indicates clipping (over-modulation) If this
happens, the gain should be reduced by turning the gain control
knob to the left
7 POWER indicator
This green LED indicates that the unit is connected to the USB
power supply
8 GAIN control knob
This control knob adjusts the analog input recording level
9 VOLUME control knob
This knob adjusts the volume of the phones monitor output (5)

Installation procedure
First download and install the RECORDER USGH software from the
Avisoft Bioacoustics website (www avisoft com/downloads htm or
directly www avisoft com/RECORDER USGH exe) This installation
program will install both the RECORDER USGH application
(rec_usgh exe) and the required device drivers (usgh_xx16h inf,
usgh sys) for the UltraSoundGate xx16H devices 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 finally activated
Under some circumstances it might happen that the silent
installation of the device driver fails If that happens, navigate to the
Windows Control Panel > Hardware and Sound > Device Manager
and right-click at the entry Other devices > Aviso t Aviso t-
UltraSoundGate 116H and select the Update Driver So tware..
option Then click at Browse my computer or device driver
so tware, click at Browse and navigate to the folder C:\Program
Files (x86)\Aviso t Bioacoustics\RECORDER USGH\Drivers and
finally click at Next The completed device driver installation will
then look like this:
To become familiar with the RECORDER USGH
software use the online help system that can be
accessed through the drop-down menu Help > Help...,
the Help... buttons on the individual dialog boxes or

RECORDER USGH Settings
User's Guide Model 116Hb
The configuration dialog box can be launched from the menu
Options/Configuration or through the button
The input sample rate can be selected from the Input Device
Settings section Available sample rates are 300, 250, 214,
187 5, 166, 150, 125, 100, 75, 62 and 50 kHz
The Buffer setting determines the USB transfer buffer size on
the PC Shorter durations will provide low real-time
spectrogram display latencies but might lead to erroneous
USB transfers under certain conditions
Enable band-pass mode At a few sample rates (50, 62 5, 75, 150,
187 5 and 250 kHz), the A/D converter can be configured for a
special band-pass mode in which the analog input bandwidth ranges
from fs/2 to fs instead of the normal mode from 0 to fs/2 This option
can be advantageous for monitoring applications that require
minimal WAV files sizes Note that the frequency scale of the
resulting WAV files will be reversed
Turn on the polarization voltage This option activates the internal
200V polarization voltage generator of the UltraSoundGate XX16H
devices and must be activated when using the CM16/CMPA
microphones
Ignore GetOverlappedResult error By default, the GetOverlapped
Result error message will stop the monitoring/recording process If
this option is activated, the monitoring procedure will be immediately
restarted, which is desired in long-term monitoring applications
TRG out mode This option has no effect on the USG 116Hb
Monitor undersampling ratio This list box allows to select the
desired undersampling ratio of the acoustic monitoring output (5)
from 2 to 30 in steps of two The internal D/A converter will be
clocked at a rate that is equal to the selected input (A/D converter)
sample rate divided by the selected ratio The resulting output
sample rate is displayed behind the ratio (= xxx Hz) For instance, if
you have selected an input sample rate of 300000 Hz and an
undersampling ratio of 10:1, the resulting output sample rate will be
30000 Hz All input signal components above the Nyquist frequency
(half of the output sample rate = 15000 Hz) will be folded down to
the range between zero and the Nyquist frequency For instance, a
30 kHz input signal will appear at the monitor output at a frequency
of 3000 Hz
The Settings... button in the Input Device Settings section
launches the Advanced USGH Device Settings dialog box that
provides several additional device-specific options:
:
The options Enable master/slave mode for synchronizing
several devices and Activate slave mode for this device
have no effect on the model USG 116Hb
Enable low power mode The A/D converter chips can
optionally be operated in a power-saving mode that would
increase the battery life in mobile laptop-based systems The
low-power mode slightly degrades the dynamic range
performance This option should also be activated if the USG
1216H is bus-powered from a single USB port only
Otherwise, the supply voltage might drop below a critical
value, which can prevent the proper operation of the A/D
converters
Sound-activated recording can be arranged by selecting the
Trigger source option level of this channel
The Pre-trigger duration should be kept as short as possible Long
pre-trigger settings can lead to data transmission errors if the
sample rate and the number of channels is high
In order to simplify the operation of the Avisoft-RECORDER
software in the field, a link to RECORDER USGH may be added to
the Windows Startup fol er (Start->All Programs->Startup)
Additionally, the Avisoft-RECORDER option Monitoring/Autostart
should be activated This arrangement will start the monitoring
process automatically after booting the laptop (the UltraSoundGate
device must be attached to the USB port prior to booting
Windows)
