Programmable RF Components in Automated Test Equipment (ATE)

Posted by Scott Blanchard on Mar 24, 2016 3:00:00 PM

In the past, large production environments and sophisticated labs were the dominant influence on the research and development that led to yesterday’s full-featured benchtop equipment market. Today, however, nimble test and verification teams are increasingly looking for more portable and cost efficient solutions devoid of cluttered GPIB cabling and specialized software. Not only has the debugging of previous generation automated test equipment (ATE) proven difficult without expert technicians, test engineers today are enjoying the flexibility of using programmable components that leverage APIs connected to commonly used software platforms.

Q & A with Vaunix: If you don’t see it here…

Posted by Scott Blanchard on Aug 18, 2015 10:00:00 AM

In our Q & A blog series, we’ve addressed some of the most important and technical questions about our Lab Bricks. We hope these answers give you a better understanding of how our products work.

We sometimes get requests for a special capability or feature that our Lab Brick signal generators do not have as standard features, which is understandable, as their optional capabilities don’t just jump out at you on our website. However, pulse modulation and external sweep triggering capabilities are optionally available for our LMS Series signal generators and an external reference input and an RF output of +13 dBm can be specified for the LSG Series signal generators.

Q & A with Vaunix: New Attenuator GUI Expands Dwell Time

Posted by Scott Blanchard on Aug 4, 2015 10:00:00 AM

In our Q & A blog series, we’ve addressed some of the most important and technical questions about our Lab Bricks. We hope these answers give you a better understanding of how our products work.

Customers and potential customers have asked us about increasing attenuator dwell time. We listened. The latest version of the attenuator user interface allows dwell time to be set at up to 500 s. If anyone needs even longer dwell times, we would be happy to entertain your request.

Q & A with Vaunix: Controlling Multiple Attenuators

Posted by Scott Blanchard on Jul 21, 2015 10:00:00 AM

In our Q & A blog series, we’ve addressed some of the most important and technical questions about our Lab Bricks. We hope these answers give you a better understanding of how our products work.

Q. If I plug four LDA-602N attenuators into four USB ports on a PC, can I address them with the attenuator software individually and change their attenuation separately as well as simultaneously?

Q & A with Vaunix: Lab Brick Attenuators, Windows, and USB

Posted by Scott Blanchard on Jul 7, 2015 10:00:00 AM

In our Q & A blog series, we’ve addressed some of the most important and technical questions about our Lab Bricks. We hope these answers give you a better understanding of how our products work.

Q. Can the LDA-302P-2 run from Windows and if so is it possible to guarantee its switching speed or does the Windows GUI just set up the profile and the microcontroller operate on the data? Is it also possible to vary the duty cycle between iterations? For example, at 1 ms we would like 0-dB attenuation and 4 ms at maximum attenuation, repeatedly continuously.

Q & A with Vaunix: Attenuators – Signal Fades and Dropouts with 3G Transceiver

Posted by Scott Blanchard on Jun 9, 2015 2:00:00 PM

In our Q & A blog series, we’ve addressed some of the most important and technical questions about our Lab Bricks. We hope these answers give you a better understanding of how our products work.

Q. We need to be able to simulate signal fades and dropouts for products with an embedded 3G transceiver. I have been looking at the LDA-302P-2 product as we need to be able to test up to 2600MHz and it needs to be able to handle a transmit power of 2W. We're not really sure how much attenuation we are likely to need to produce signal dropouts, would you think that 90dB would be sufficient? Is this model the most suitable for our requirements?

Getting to Know Lab Brick Part Four: Attenuators

Posted by Scott Blanchard on Mar 10, 2015 11:07:49 AM

Few instrument set-ups are complete without attenuators, as without them your ability to evaluate the performance of your device under different conditions would be severely limited. Our Lab Brick attenuators combine both the performance and the configurability you need to provide a wide range of measurement flexibility, and setting them up is performed the exact same way as all of our products – from a single display. (If you're unfamiliar with our Windows-based Lab Brick software, start with the first post in this series to learn more.)
