AndrewModeratorHello Nana,
Did you mean to type SA series instead of RA series? If you did, then yes, the bbr file format is the same for all devices.

Hello Ossian,
After our phone conversation, I received confirmation from the owner that we would be willing to look at the device free of charge to determine if there is an issue. If this is of interest to you let me know.
Regards,
A.J.

Hello Ossian,
The warning informs you when any portion of the signal is greater than the reference level. Typically to warn users when they are approaching compression or when the measurements are being drawn off screen. For the whole trace to not appear on screen with that warning can be the result of a couple things. Is it possible the entire trace is higher than the reference level? This is possible if you accidentally set the reference to a very small number. You can click anywhere on the screen to see a marker reading. What does the marker read in amplitude? I remember you were looking to install a USB card in your PC. It is possible invalid values are being returned to the PC creating bad numbers as well, potentially due to some incompatibility with the card you were installing.

AndrewModeratorπ/4DQPSK will be included in both the VSG25A and the digital demodulation software. The digital demodulation will be available only for the BB60 series at first, but we will be adding support for the SA series in the near future.

Hello Ossian,
Supporting the tracking generator requires firmware level support. The firmware differs between the BB60A and BB60C so the changes made for the BB60C to be supported did not carry over to the BB60A. We do not have plans at this point to pursue this, but it is not out of the question.
The BB60A is not abandoned though. It still receives PC software level support as we continue to update the Spike software application. In fact the digital demodulation capabilities we are adding late May will be supported for both the BB60A and BB60C. The BB60A shares the same programming interface as the BB60C (by design) so that anytime we make PC side changes/additions/improvements both devices receive the benefits.

A.J.
AndrewModeratorHey everyone! Here is a sneak peak of what we have been working on since the beginning of the year. On the left we have the new interface to our upcoming vector signal generator (named the VSG25A) and on the right you can see the upcoming digital demodulation capabilities of the BB60C/A within the Spike software application. The VSG is transmitting a QPSK modulated signal at 890MHz and the BB60C is receiving the signal and triggering on a sync pattern. Both are expected late May.
The VSG25A is priced at $495 and the digital demodulation capabilities will be part of the next Spike software release.

Hello Victor,
I apologize for not making this more clear on our website. The added tracking generator compatibility is only compatible with the BB60C. I apologize for the confusion.

Hi Victor,
Thank you for your updates and patience. I looked into this a bit further, and I hope I have come up with a solution. Start with a fresh download of the firmware updater folder and install this driver from FTDI. Link below
https://signalhound.com/sigdownloads/Spike/CDM%20v2.12.00%20WHQL%20Certified.exe
The ftd2xx.dll/bb_api.dll you dropped in are likely 64-bit versions. The FTDI driver install will be necessary for using the TG44/TG124 and will install the 32 and 64-bit versions. I think this is the missing piece. The firmware updater is a 32-bit application and installing the FTDI drivers hopefully will install the last missing DLL.
Let me know if this works.
Regards,
A.J.

Hi Victor,
Yes, version 3.0.7 means that you can now pair the BB60C with a TG44/TG124 and make scalar network measurements. Yes, you will need to update your existing BB60C to firmware version 5.
I just added two links to the BB60C downloads page under the firmware updater download. To run the firmware updater, you will need to download/install two Microsoft libraries. I apologize for the inconvenience.

A.J.

Hi Mervin,
Thanks for updating us on your situation. I am glad a newer release seems to have resolved your issues.

Hello Mervin,
Can you please email support@signalhound.com to begin the support process.
Please send information regarding your setup such as the current configuration of the software, such as frequency range, and the tracking generator control values you are setting when seeing this issue. Also please describe what you mean by “remove the SA/TG” and what kind of error messages you are seeing on screen. Also please share your PC information with us, most importantly, the Operating system, whether you are 32/64 bit and the CPU model number. Any other information you can think of that is unique to your setup or measurement process is helpful so we can try to duplicate the issue or determine its source.Regards

Julian,
I might be the best person to answer this. Yes, a good noise source will work, but it will suffer from:
1) Dynamic range. Since your energy is spread through the entire spectrum, the energy at each frequency bin is quite a bit lower. You might only get 40 dB of dynamic range, instead of 90 ish.
2) Nonlinearities. If you are trying to test the frequency response of a device, and “zero out” the response at some maximum amplitude for best signal-to-noise ratio, you may have significant intermodulation products affecting your readings. When you insert your DUT and filter some of them out, your flatness may be less than ideal.
3) Lack of automated software support. With the TG44AA / TG124A, you get software specifically written to do the task, saving you time and potential errors.
AndrewModeratorHello Julian,
Currently we have not implemented quasi-peak detectors in the BB60. Expanding our EMC functionality is something we are planning on doing the second half of this year. We have a number of features requested by users and that we want to implement ourselves that fall within the realm of EMC precompliance.
I am not familiar with any 3rd party software that uses our unit for EMC pre-compliance.
The real-time functionality of the BB60 is great for EMI testing.

A.J.
AndrewModeratorHey Dan,
Here is the direct link to the archived ARM build.
https://signalhound.com/sigdownloads/SA44B/arm_sa44B_api.zip
Compiled on a beagleboard with GCC, Cortex A8 processor.Regards,

AndrewModeratorHello Feng,
Video triggering is not a function of the API. If you need video triggering you will need to check the amplitude of the I/Q samples against your trigger level as you acquire them.
Let me know if you have any other questions.

A.J.
AndrewModeratorHello Richard,
Thank you for bringing this to our attention. The Spike software does not have extensive text scaling capabilities for high DPI screens like the Microsoft Surface. Other users have had varying success with the Windows text/icon scaling. Have you tried this yet? Other than the Windows text/icon scaling, the only other alternative we can suggest is to reduce the screen resolution. I apologize for the inconvenience. It is something we are planning on looking into in the future.
Regards,
A.J.
AndrewModeratorHello Dan,
Unfortunately all of our programming interfaces are proprietary, so we cannot share the sources. At this point the Linux and ARM libraries are provided as is. We have focused our efforts on our Windows libraries releasing a large update/overhaul about 1 month ago. At some point in the future we might re-visit Linux and bring over the major changes we made on the Windows side, but we have no definite plans as of yet. I apologize for the inconvenience.
Regards,
A.J.
AndrewModeratorHello Feng,
You did not state whether you are using the API or using our supplied software. If you are using our software then you can setup video triggers in zero-span mode using the control panel. If you are using the API and retrieving IQ data from the device directly then video triggering is just a function of checking each IQ sample for you trigger level.
If this does not answer your question, please try to restate your questions.
Regards,
A.J.
AndrewModeratorHello Mark,
I can explain what you are seeing, and clarify the difference in behavior between the old software and new software.
As you know, a frequency bin in a sweep rarely lines up nicely on an even number like 10MHz. When you enter a marker frequency like 10MHz the closest frequency bin has to be used, and it might correlate to a frequency like 9.999037MHz. The old software simply printed the frequency you entered even though it was using the frequency bin at 9.999037MHz while the new software will simply show you the frequency of the bin used.
Ultimately both versions of the software use the same frequency bin to report the amplitude but the old software shows you the frequency you entered and the new software shows you the actual frequency of the marker.
Let me know if you have further questions.
