AndrewModeratorHi Emo,
I apologize, are you pointing out that the arrow buttons are covering the frequency text entry? (or that the arrows are really small?) Are you able to resize the width of the control panel? The new release was supposed to make it so users could do this. I look forward to your response.

AndrewModeratorHi Jan,
At the end of the Spike installer it states that you will need to install the additional USB drivers found here
https://signalhound.com/sigdownloads/Spike/CDM%20v2.12.00%20WHQL%20Certified.exeHave you already installed this? If you have not, you will need to run the installer as administrator.
I apologize for the inconvenience, hopefully we can get this resolved quickly.

AndrewModeratorHi NopMicro,
When you say FM demod you are referring to demodulating and playing the resulting audio waveform? The Spike software has an audio player in the utilities file menu. We are also compatible with an SDR application called HDSDR which has much more extensive audio playing capabilities. You can find the files and setup guide for HDSDR compatibility at this link.

AndrewModeratorHi Tishers,
Good timing, I am looking at QAM64 today. QAM256 will likely follow if I can get QAM64. I’ll take a look at your other suggestions as well. Out of curiosity, which view where you imagining a horizontal line displayed on? The spectrum plot?

AndrewModeratorHi Paul,
Thanks for calling in. You have my contact info if you have any questions in the future.

AndrewModeratorHello rtcjss,
I personally have never used CVI but I have seen these types of issues before. You are seeing this because our API is not 100% C compatible. It is going to complain about missing typedefs on the enums and structs and maybe a few other things. I think if you addressed this, the CVI compiler would be able to parse our header file without errors. This is just a guess though. Without CVI, I cannot test this.

Hi Steve,
As of today, we have released a new version of Spike which will allow you to adjust the reference oscillator in your SA44, unfortunately it will not work with your TG.
Grab the new version of Spike at http://www.signalhound.com/Spike and check out the “Timebase Adjustment” under the utilities menu. You will input a CW into the RF input of the SA44, specify its power level and frequency and you can make one click adjustments. This should get your SA calibrated. It is a software calibration and can be reversed anytime by clearing it through the same utility.
Hope this helps, let me know if you have further questions.

AndrewModeratorHello facotl,
Is the LED on the device solid green? Have you tried a different usb port? When the device is plugged in, check under the device manager->Universal Serial Bus Controllers tab and you should see “USB Serial Converter A” and B. If they are there, right click -> Properties. Under the advanced tab, ensure the “Load VCP” checkbox is not selected.
Also, is this the first computer you have tried? If it is possible to try on another computer, it would help rule out certain issues, like a bad cable/hardware.
Let’s start with this, I look forward to your response.

AndrewModeratorHi Everyone,
Today we are releasing version 3.1.0 of the Spike software. With this comes EMC pre-compliance measurements and features for the BB60A/C users, frequency difference meter utility, temporary time base adjustment utility, ability to hide control panels, and we moved the API files out of the installer into their own separate download. Check out the change log on http://www.signalhound.com/Spike for more details.
Also keep an eye out for the next update where we will be attempting to resolve many of the text scaling issues for high DPI displays.Regards,
A.J.
AndrewModeratorHi bbowar,
I apologize, I am currently out of town and cannot verify, but I believe changing the values 486111.111 to 80.0e6 will correct the equation for the BB60C.

AndrewModeratorHi bbowar,
We distribute a linux build of the BB60 API on the BB60 downloads page. Usually it is a few versions behind the main distribution.
You will find it near the top of the list on this page

AndrewModeratorHi Andy,
Actually what we do is,
For each column where the sweep size is substantially larger than the max image width (1024), we divide by an integer(n) number, and plot an ‘n’ points on that column.Regards,

AndrewModeratorHi Nikita,
This is a very interesting idea, thank you for the suggestion.

AndrewModeratorHi Jacob, this a limitation of the Spike software that will need to be resolved. Currently there is no way to specify the output format. I apologize for the inconvenience. You may need to export as dBm and perform the conversion manually. I will make a note to investigate this issue and see if there is a quick fix for this.
Regards,
A.J.
AndrewModeratorAndrew May 25, 2016 at 9:19 am in reply to: USB-SA44B – signal level is dependent from reference levelHi Nikita,
Yes, the noise floor is tied to reference level. This is because we optimize attenuation and gain of the receiver based on the reference level. This makes it easy to configure the receiver for your expected input signal. If you wish you can control the gain and attenuation manually by enabling it from the setting file menu. This way, you have consistent measurements across reference level.

AndrewModeratorHi Andy,
The frame scale represents the total height of the real-time frame in dB. For example, with a frame scale of 100, a frame column will represent amplitudes between the reference level and the (reference level – 100).

AndrewModeratorHi Hank,
The peak values are the measured min/max frequency deviation values. I hope this answers your question.

Hi Sam,
The bbr files can be loaded back into Spike. If you press the play button on the sweep recording toolbar and select the bbr file, the software will sequentially play back the sweeps recorded in the file. You also have access to all sweep measurements when playing the file back through Spike.
You can also parse the file programmatically. I am attaching a file which shows how one would parse the bbr file in C. I would imagine it would be very easy to adapt this to Python. The format is very basic.
Let me know if you have further questions.

AndrewModeratorHi Mervin,
For the SA and VSG devices, the symbol rate limitations on QAM16 are going to be between 16kS/s and 150kS/s. The VSG is capable of generating QAM64 and QAM256 patterns but the SA is not able to demodulate them currently. You can configure a QAM signal with up to 512 symbols. I have attached an image of this setup.
If you have further questions, let me know.

AndrewModeratorAndrew May 12, 2016 at 11:51 am in reply to: SA44B – "Device not found" error, another possible solutionHello Han,
As a preliminary check, have you installed the USB driver from the http://www.signalhound.com/Spike page? When you install it, it will require you to run as administrator (Right click -> Run as Administrator)
You have the necessary y-cable for power? You should connect both PC side connections first before the SA124 side. You should see a green solid LED if the device is properly powered.
Typically connecting a device to the PC for the first time will cause the PC to “load” the driver. You should see some activity in the task bar noting this. It should notify you when done. This can take anywhere from 10 seconds to 1 minute. If you try to launch Spike before this completes, you will get the Device not found error message.
Most customers experience issues with our products on Apple computers, whether in a virtual machine or natively through bootcamp. I would try getting it to run successfully on the PCs first before the Macs.
Sometimes, anti-virus software conflicts with our devices and needs to be disabled/reduced.
I look forward to your response.
