Hi Jan,
Thanks for the request. I could see this being very useful. I know we have talked about implementing trace math in the future. I think that would be a good time to add trace normalization as well.
Cheers,
A.J.Hello zhubajel,
I apologize, I may not fully understand your question. I will try my best to describe the purpose of the cal files.
The cal files contain the correction information needed for the device to make accurate measurements. The cal files are generated and are different for each device.
Any time you use the API to control the device, the files are stored and read from the ProgramData/ folder. The ProgramData folder is the place Windows expect us to use to store this kind of information.
I have recently emailed you about an issue on a different forum thread, if you would like me to send you the cal file we have for your unit we can so you can verify it is the same as the one pulled from your device. Let me know if you want this in your email reply.
Regards,
A.J.Hello zhubajel,
I will be sending you a support email using the one provided in your profile. If this email is not correct, you can email me at aj at signalhound dot com.

A.J.Hello Mervin,
There are several ways to calibrate the SA44B.
We provide calibration software to the user. You will need several pieces of equipment to perform the test, and you can find the required equipment list in the calibration manual. Both the software and manual can be found on the SA downloads page under “calibration software”.
https://signalhound.com/support/product-downloads/sa44b-sa124b-downloads/There are also facilities that will calibrate the SA44B with various accreditations. We provide a list of facilities on this page,
https://signalhound.com/support/spectrum-analyzer-calibration-services/And finally, you can send the unit back to us for calibration. You can set up a calibration through our facilities by contacting us by phone or email at lori at signalhound dot com.
As for the TG, the only calibration available is through our facilities.
Let us know if you have further questions.

A.J.Hi 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.

A.J.Hi 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.

A.J.Hi 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.

A.J.Hi 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?

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

A.J.Hello 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.

A.J.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.

A.J.Hello 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.

A.J.Hi 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.Hi 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.

A.J.Hi 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

A.J.Hi 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,
A.J.Hi Nikita,
This is a very interesting idea, thank you for the suggestion.

A.J.Hi 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.Hi 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.

A.J.
