Giga-tronics has released the Series 8800, a range of Ascor common-core-based signal switching products designed to meet test requirements in defence and aerospace applications, for example.

This new range of products provides a modular RF/LF/DC switching platform that is scalable and reconfigurable to meet existing and emerging test requirements covering the DC to 50GHz frequency range.

The standard Series 8800 incorporates 12 switch modules that can be equipped with various relay configurations, including multiple SPDT through SPnT (n=3-6) relays in both terminated and non-terminated versions.

Other relay configurations are also available.

Modules can be added or replaced when test requirements change.

Should other signal conditioning components be required, there is a place to add components such as programmable attenuators, amplifiers, filters, circulators/isolators and power dividers/combiners.

Front and rear panels can be tailored to a specific application – with custom labels for radio-frequency interconnection, if needed.

Relays can also be mounted directly to the panel to maximise relay performance (relative to internally integrated relays that will have additional cable loss and increased path VSWR).

In addition, when test requirements change, the panels can be replaced with ones that are more specific to the new application.

This enables the reuse of the common core of relays and other components for other projects.

The Series 8800 integrates the Giga-tronics Ascor GT-8300A model.

This mainframe accepts a variety of Series 3000 modules.

With nearly 200 existing designs available, users can supplement the radio-frequency switching capability with DC and low-frequency switching as well as digital I/O and DMM functionality.

Walt Strickler, vice-president of business development for switching solutions, said: ‘In the aerospace and defence test community, many projects and programs build their own test systems because they believe that their test requirements are unique and/or because of the sensitive nature of the project.

‘Building unique test systems is much more expensive than leveraging a common-core platform and often does not take advantage of the collective learning over a wide variety of applications.

‘Activities have been undertaken to make common-core testers available.

‘The Giga-tronics Ascor Series 8800 embraces this concept and provides a common core available at the switching/radio-frequency interface unit level,’ he added.
