Defence Services Asia 2012 - DSA Kular Lumpur, Malaysia
Monday, 30th Apr, 2012
CommsAudit exhibited at Defence Services Asia 2012 in Kuala Lumpur over 16-19th April. Visitors to the CommsAudit stand included Defence, Police, Security, and commercial organisations. CommsAudit were exhibiting a range of products including receiver systems, antenna distribution multicoupler & switch matrix systems, and UWB antennas. CommsAudit would like to thank all for visiting our stand at DSA2012.

CommsAudit exhibited at RadCom 2012. Mark Minall, (CA Business Development & Sales and Marketing Manager) was in attendance and is shown in the photo at the TacTron stand with Georg Schmidt (Gen. Man. of TacTron Elektronik GbmH & Co KG and MD of Gerotron Communication) and Guenter Weikamp, CommsAudit's new representatives for Germany, Austria and Switzerland.
Dr Iain Scott (CA Dir of Technology) was presenting the CommsAudit White Paper; Narrowband vs Wideband Tuners in the HF Spectrum; highlighting the advantages of narrowband tuners over wideband with their enhanced ability to pick out small signals that may be otherwise swamped by larger adjacent signals. The SFDR and sensitivity of the CommsAudit CA7708 8-channel HF Narrowband receiver makes it a world leading example of such a narrowband receiver. As such, with it's 8-channel capacity, it makes an ideal replacement for legacy HF receivers; both enhancing the users system capability and saving rack space.
Abstract from the White Paper:
Narrowband vs Wideband Tuners in the HF Spectrum
In recent years, Software Defined Radio has proven to be a highly effective approach to radio system design. This has naturally led receiver designers to digitise as early as possible in the signal path. Processing data digitally enables the flexibility promised by software defined systems.
This approach is inherently wideband in that it samples large regions of the available spectrum. With modern processing technology, it is entirely possible to simultaneously process the entire HF spectrum. This is particularly important for regulatory and defence organizations that wish to capture and analyse short duration signals.
However the available dynamic range of current analogue to digital converters (ADC's) means that small signals can be lost in high dynamic range environments like the HF spectrum. Small signal prosecution therefore requires analogue filtering ahead of the ADC; i.e. successful small signal prosecution requires the use of a narrowband approach.
This paper discusses these two approaches to system design and their relative benefits. A new tuner system currently under development by CommsAudit is also presented as a novel method of combining the merits of both approaches.
