Engineer Liang Rong Zhou explains how LabSat has brought about significant time savings:
“Before we can complete chip tapeout (the signoff for a new circuit board) we need to test hardware logic and software systems on the FPGA and we do this in two ways: in the lab, and live. LabSat is exceptionally useful for doing live signal testing. Compared to traditional testing methods, we find that by using LabSat we are three to five times more time efficient.
This is thanks to a number of reasons, principally:
This is the testing of small batches of products.
The engineers at Huaxun use LabSat in place of a signal generator for sensitivity testing as it’s more realistic; and this realism is extended because scenarios from every part of the globe can be used, rather than just from the local live-sky signals.
According to Liang Rong:
“The variety of scenarios give us a complete solution. We don’t have to travel half way round the world to be able to test there, just like we don’t have to actually use a sports car (with the added cost for both car and fuel) to do pilot testing with high dynamics - it only needs recording once and then we can use it as often as we like.
Further convenience comes from LabSat’s small form factor and standard connectors – this makes building a test environment much simpler than before.”
The LabSats in use at Huaxun are not only used in a laboratory or production line setting – they are also employed on the other side of the business:
“Finally” Liang Rong continues, “the fact that LabSat scenarios can be shared has proven invaluable to our field application engineers when solving problems for customers.”
LabSat systems are used daily across the world by GNSS chipset manufacturers including:
