LINALYZER
is a single phase Mains supply analyser combined with software to provide non specialists
with an efficient and highly performant decision aid related to electricity supply
misbehaviour and energy cost analysis. The LINALYZER was honored to be selected as a
finalist of the " Best of CeBIT95 Award ".

The technical performances of this
measurement tool that works in relation with a battery powered DOS PC are oriented towards
European Mains supply characteristics: 200 VAC - 50 Hz. The LINALYZER electronic circuitry
makes 100 measurements per cycle (5000 measurements per second) about Mains voltage and
current. Information is accurately time stamped. All significant energy fluctuations such
as drops, breaks and spikes amplitude and duration as well as eventual presence of high
frequency noise reaching a perturbant level are registered.
The LINALYZER control
software is very user friendly. Communication is actually performed in English, French,
Dutch, German, and Spanish. The information sent via the serial port of the PC is
displayed and collected in a spreadsheet compatible format. Measured data is analysed and
significant results are interpreted in practically oriented jargon free corrective
suggestions. Competent users can later make use of any popular spreadsheet program to list
measured values, select elements of interest and perform more in depth analysis including
graphics.

Our extensive product
range includes single, dual and multi tape subsystems based on DLT, AIT, MLR, Mammoth and
3590 drives, Fibre channel and Storage Area network products, SCSI extenders for remote
operation of disc and tapes and SCSI switching and SCSI Converter solutions. Our
tape encryption unit Paranoia designed to ensure security of data to tape whatever the
host platform.
Products
produces a wide range of connectivity and storage devices across a wide
range of host platforms. Products include DLT, AIT, Mammoth and 3590 based tape devices,
SCSI extenders up to 90 Km, on the fly tape encryption, crossbar switches up to 16 x 12
and now a range of fibre channel devices.
Paranoia In
line tape encryption unit
The Paranoia is
a hardware data encryption unit designed to encrypt / decrypt data on the fly between a
host system and a high speed SCSI tape drive. The unit is designed to provide a high level
of data security for tape data in vaulted storage or when it a shared tape silo
application. It is designed for use in an unattended backup environment. Where large
amounts of data need to be physically transferred between sites two Paranoia units are
used to unsure the data security whilst the tapes are in transit.

SystemBase
Digital Audio CodecsPROFESSIONAL
QUALITY AUDIO
The C400xr and C310xr digital audio codecs, have been designed and manufactured by
Systembase to deliver unparalleled performance for professional, real-time audio
applications. Both models incorporate the fast apt X100 Sub Band ADPCM compression system
with a coding delay of only 3.8ms.
Additional design
enhancements based upon the use of a 20 bit conversion process, have extended the audio
bandwidth by almost 900Hz, resulting in a much richer natural sound.
REAL-TIME
BI-DIRECTIONAL OPERATION
Systembase codecs incorporate both an encoder and a decoder, to provide a real-time, full
duplex audio circuit. The short coding delay of 3.8ms at 32KHz sampling rate, makes them
suitable for bi-directional applications such as outside broadcasts (OBs), studio to
transmitter links (STLs) and remote voice-overs. In addition, the integral ISDN
inverse multiplexer, used to synchronise up to four ISDN B Channels, introduces a delay of
just 0.5ms.
CASCADE
AND TANDEM CODING
Systembase codecs allow cascade or tandem coding of audio with minimal degradation in
quality. This feature is essential when contributing to Digital Audio Broadcast (DAB)
radio or television stations using MPEG technology. In both cases, the use of
psycho-acoustic compression, limits the number of times the audio signal can be encoded
and decoded with a similar type of algorithm, before audible artefacts occur. This problem
is overcome by Systembase codecs, which introduce a minimal I.7dBm of quantisation noise
following each encode/decode cycle.
INTELLIGENT
FEATURES
In the event of an ISDN call failing, the codecs will automatically drop down to provide
the next best available service with the remaining connected calls. The user can configure
the codecs to prioritise between bandwidth or stereo image. When operating in Mono, they
have the capability of monoising the left and right input audio channels, and provide a
pseudo stereo service to both the left and right outputs. In Dial-on-Audio, Trigger Dial
or ISDN Backup modes, the codecs will automatically re-dial the ISDN lines if a call fails
or disconnects.

REMOTE
MANAGEMENT
Remote management facility is provided as standard, and enables full remote control and
re-configuration via a computer. Multiple units can easily be linked together using a
simple daisy-chain topology, and controlled centrally from a single computer. There are no
limitations on the number of units that may be connected together. A codec unit at a
remote or unattended site can readily be controlled by using standard analogue modems.
