Mind numbing transfer speed.
Video Transcript:
– This marvel of 1970’s engineering launched one of the big three test and measurement companies. It’s called GPIB.
It allowed you to transmit one megabyte per second between a spectrum analyzer and a computer. But today’s RF instruments generate so much raw data that, well, you would need 10,000 of these cables to handle it all. So, I think we’re going to need something else.
This two channel RF recorder produces data at a mind numbing rate of 10 gigabytes per second.
To accomplish this feat, it uses an array of internal solid state drives.
After the recording is finished, you’ll probably want to offload the files from the internal storage so that you can share them with colleagues, pull them into MatLab, or just back them up. To do this, you might be tempted to the obvious solutions, right?
A USB thumb drive, or hard drive. While you certainly could do that, you’ll be standing there for 40 minutes waiting to transfer just 20 seconds of RF recording data. That’s not exactly my idea of productivity.
These are the right tools for the job.
Fiber, SFP, and SAS.
These have the ability to reduce a 40 minute wait time to a two minute wait time.
But don’t just take my word for it, check out this screen capture to see exactly what I’m talking about. Here we’re offloading a large file from an RF recorder.
One of these is offloading the file to a USB hard drive, then other to a direct connect SAS disk array. Can you guess which one is which? Do you feel kind of bad for the person trying to use USB right now? As you’ve probably heard me say before, workflow matters. And choosing an RF recorder designed to offload files as quickly as possible will make a huge difference in your productivity.
