The salesman is partially right. Where he is wrong is that he knows nothing of the specific application of utilizing a FLEX-5000 or FLEX-3000 and the isochronous *throughput* (not to be confused with bandwidth) required to run the radios at 192 and 96 KHZ sampling rates, respectively.
The proclamation of the death of Firewire is a bit premature. USB3 is an emerging technology and it has its fair share of bugs. Microsoft is still having problems with the USB1/2 on Win7 operating in an isochronous manner. Ten years ago when USB first came out, all the pundits said that you could not find a RS232 serial port in 3 years. I have serial ports in all my PCs today running Win7 x64. I suspect I will have them in 5 more years too. Firewire is not dead and there are still a plethora of manufacturers making Firewire due to the video and audio recording industry. Eventually you will see more and more devices moving to USB3, but it will not happen at a fast pace. I would not be too concerned that Firewire is going to disappear any time soon. In regards to 500/3000 replacements using USB3, FlexRadio has made no announcement of any kind regarding any replacement of the FLEX-3000 and FLEX-5000, so it is a safe bet that they will be the mainstream high performance SDR offerings for the foreseeable future. -Tim -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Friday, February 11, 2011 10:49 PM To: [email protected] Subject: [Flexradio] USB3 - Firewire I was perusing Best Buy today looking for a replacement household computer and discovered virtually no systems with FireWire. The salesman's pitch was that USB3 will be the functional replacement. I believe he is right. I am not sure what USB3 speed is, but I'll bet it handily outpaces Firewire. I know - latency is a different matter. Will Flex be offering 5000/3000 equivalents with USB3 connectivity? My 1500 is a beautiful little USB2 package, so it looks like the heavy lifting software wise has already been (is already being) done. We surely don't want to end up tied to a legacy connection - like a latter day Serial port.
