One with persistence showing the two devices.

I am attempting to use the digital demodulation as you have shown. Maybe a full screen shot would help so I could see all of your settings. I assume the problem is the operator. Maybe if I do a better job explaining, you can help me out.

The first plot showing a peak hold of the two tones.

Second plot showing the two devices. Slave device sends more data and has the lower amplitude.

Third plot zooming in to see the bit rate which appears to be roughly 1200bps.

Now when I try to decode this with the digital I need to use much higher sample rates than 1.2K before the spectrum shows the two spurs. If I use 50X over sample (60K) the eye diagram looks correct and I can see the preamble but a 0 will be represented with 50 zeros sort of thing.

Any help in what I am doing wrong would be greatly appreciated.

Thank you for the consideration.

It is a Dell Precision 5810. Windows 10 Pro, 32G RAM, 3.6GHz Xeon E5-1650 V4. I am using an M.2 drive.

It seems like it could auto recover just in that Windows sees the device. It looks like the device hangs in a way where it can’t recover without a power cycle or it sees the connection closed when the driver is shut down in control panel and then allows spike to reconnect.

I thought I would give you an update on this. After buying the new PC, the BB60C has been behaving for the most part. I had mentioned how the hardware (BB60C) gets into a mode where Spike will not talk with it. The green LED will be active on the BB60C. I can exit Spike and restart it and it will not talk with the BB60C. The device manager finds the BB60C and reports no problems. To recover, the BB60C must be unplugged or I can stop and restart the driver. You may recall this happens VERY infrequent. It does not seem tied to running from an external hub or extension cables. When I first purchased the BB60C, I put a lot of hours on it and I don’t think the problem showed up more than 10 times. I thought it was tied to on particular port on the Dell PC. I have settled into using the unit and the problem has not came back even with the extension cable and hub. Until yesterday. After several hours of running, it hung the same way.

I ran it today for about 4 hours and it’s back to working flawless.

Strange.

I will send you a direct email. The PC is a laptop, ASUS Model G73Sw. It has an Intel i7 2630QM 2GHz processor, 12G of RAM and 64-bit Windows 7 SP1 installed. Graphics is an NVIDIA GeForce GTX460M.

This is the first time I ever looked at the BB60C. I do not have another PC that I can try it with. I ran it for several hours in swept mode, then several hours in real time. There were no problems at all. Most problems seem to be related to changing back to swept mode.

The manual is pretty sparse and did not offer much for suggestions. I did disable the virus scanner (MS security) as the manual suggested and it had no effect. Also, I noticed in the manual how the software has a manual connect. This actually seems to allow me to recover from a disconnect without restarting the software.

Hope this helps. Again, if you have anything you would like me to try, let me know.
