Apollo Box

Acoustic analyzer
Data Acquisition System with 24-bit ADC and USB Interface

Overview

The Apollo-Box is a flexible and reasonably priced 2- or 4-channel data acquisition system with a USB interface. This small and robust box transforms a PC combined with our flexible software into a high-quality multi-channel acoustic analyzer for a wide variety of acoustic and vibration measurement applications.

Based on your measurement requirements you may choose from variants with 2 or 4 LEMO7 inputs or 4 BNC inputs. Further additional channels extend the functionality of the Apollo-Box. Among others 8 additional low-sample-rate channels and 2 tacho or trigger channels are available. You may also use the Apollo-Box as a channel extension to the Soundbook MK2 measurement system, for example.

The Apollo-Box is the ideal tool for:

• Occupational safety and environmental protection
• Engineering services
• Quality assurance
• Research and development

For multi-channel systems with 4x Apollo_Box or 3x Soundbook_Expander an extension to 32 channels is possible.

The measurements you may implement with the modular software packages we offer include:

• Sound level measurements
• Frequency analysis
• Signal recording
• Human vibration measurements
• Pass-by noise measurements
• Building acoustics
• Machinery vibration measurements
• Modal analysis
• Order analysis
• Structural analysis

Core features

Flexible operation at any PC in your company via USB interface

The light-weight, portable Apollo_Box is especially well-suited for companies which want to use measuring instruments at personal work stations. Our customer-friendly license model has been adjusted for this application. In this configuration Apollo serves as a hardware dongle. You simply have to install the software license on the corresponding PC once. The software license will then be activated automatically when Apollo is connected to the PC. Thus all purchased licenses are available for each measurement without any additional steps.

Highest quality at fair prices

The Apollo_Box contains the same high-quality measuring instrument assemblies as our PTB-approved Soundbook_MK2. So even at a low investment level you will be provided with top-level measuring equipment.

Extendable to up to 36 channels

Using the Expander_SYNC-Hub up to 4 additional Apollo_Boxes and Soundbook_Expanders may be simultaneously used in sample-synchronized operation. This allows measurement system configuration with 2 to 36 measuring channels and many additional service channels for a wide variety of applications. Furthermore the Apollo_Box may be utilized as channel extension for the Soundbook_MK2.

Comprehensive service channels permit universal application

Comprehensive service channels enable additional acquisition of 8 slow process signals with 24 bit DC ... 200Hz, external triggering with an adjustable trigger level or speed measurements with 2 tacho channels at a sample rate of 0,1Hz – 6MHz as well as connection of a GPS receiver.

Highest precision provided by a 24-bit ADC in combination with a new powerful Apollo filter processor

Our new powerful Apollo filter processor allows highest-precision real-time analysis with a large number of channels. Integrated weighting filters complying with IEC 61672 for sound level meters, Class 0 filters complying with IEC 61260 for the 1/3 or 1/1 octave analyzer, HVMA weighting filters complying with DIN EN SO 8041, ISO-2631, ISO 5349, ISO-8662, UNI-2614, UNI-11048 and UNI-9916, filters for the evaluation of mechanical vibrations complying with DIN ISO 7919, ISO 2954, ISO 10816 and DIN45666 as well as high and low pass filters provide resource-saving calculation directly on the hardware. 24-bit ADCs safeguard a high signal bandwidth with a linearity range >110dB (typical) complying with DIN 61672, crosstalk <80dB, phase error <0.01°@20kHz and a sample rate of up to 204.8kHz (switchable per channel).

One single measuring instrument for a wide variety of applications

Our extensive software range makes the Apollo-Box a universal measuring instrument for nearly all application fields in sound and vibration measurement.

The basic scope of the SAMURAI standard software already includes the virtual measuring instruments for time signal, sound level meter, 1/3 or 1/1 octave and FFT analyzer and reverberation time analysis. All values are calculated in real time and for each channel. SAMURAI allows data acquisition and real-time analysis as well as the post-processing of measured values without the need for data format modification due to the use of different software applications.

20V and 63V microphone polarization voltage for measuring range extension of standard condenser microphones

Apart from ICP/IEPE supply the Apollo_Box offers polarization voltages of 20V, 63V and 200V. The additional voltages of 20V and 63V cause an up-shift of the dynamic range by 20dB and 10dB for a polarization voltage of 200V. This eliminates the need for special microphones for high sound pressure levels, provided that the microphone is rated for high sound pressure levels.

High-precision synchronisation via cable or GPS

The Apollo_Box offers wired sample synchronisation with less than 0.5° phase difference up to 80kHz. Highly precise GPS pulse synchronisation with an accuracy of less than 25ns allows data synchronisation over a network of measuring stations that are miles apart.

Software and drivers naturally downward compatible

The downward compatibility of our drivers and software ensure long-term investment planning. Our SINUS_driver and SAMURAI support all new and legacy SINUS measuring instruments.
