Re: SMB Clock output in presence of XB-200 nay?/yea but..? how?

Thanks to all for your inputs and advice. It's very much appreciated. I'm looking at the FGPA and whether modifying its programming may be a route to getting what's needed. In due course, I'll post how I get on...

Re: SMB Clock output in presence of XB-200 nay?/yea but..? how?

Hi, Thanks for the reply. I didn't make myself clear enough it appears, so let me try and clarify: What is needed is a clock signal from a single bladeRF (or an XB200 board attached to that same bladeRF) that is phased locked to that bladeRF's master oscillator. The clock signal is only needed at a ...

Re: SMB Clock output in presence of XB-200 nay?/yea but..? how?

Hi, Re-posting this in case anyone can help me... So, ultimately what I'm working on is to use the bladeRF to do pseudo-Doppler direction finding. I wish to do so at frequencies that require the use of the XB200 transverter with the bladeRF e.g. the 2 meter amateur radio band - 144-148MHz. To do pse...

SMB Clock output in presence of XB-200 nay?/yea but..? how?

Hi, Question about the SMB clock (output) on the bladeRF (my setup; x40 with firmware v2.0, FPGA v0.5 and using XB-200 transverter board. Running on linux, using libbladeRF version 1.8.0). In the 1.7.2 API documentation (most recent I've found online) relating to SMB clock port control ( https://nua...

Re: bladeRF being (USB) disconnected during FPGA firmware recovery

UPDATE

bladeRF USB disconnect was being caused by the laptop being docked in a docking station, something associated with USB ports and the dock was giving rise to the disconnects. Removing the laptop from the dock eliminated the issue.

In case anyone should encounter this issue...

bladeRF being (USB) disconnected during FPGA firmware recovery

So, I attempted to update the FPGA firmware on my bladeRF x40 while it was connected and powered by a Raspberry Pi 2. Something didn't go right (power voltage dip I suspect) and the firmware update didn't take. No big deal, there's a fix i.e. upgrading using the FX3 bootloader i.e. as is set out at ...
