How to set parameters to improve speed?
hello Andrew: We use sa44b to measure the signal strength of external equipment(Center frequency is 27MHz),Now only 5 values can be collected per second。How to set parameters (such as span, RBW, mode) to obtain as many sampling values as possible?For sa44b, how many signal strength values can be sampled per second at most? We look …
Get Firmware String
Trying to get the firmware version from a SA44B. Spike says it is 2.12. I must be doing something wrong…. I’m using C# and this code, but I’m only getting Zeros: public static string saGetFirmwareString(int device) { char[] firmware_version = new char[16]; if (saGetFirmwareString(device, firmware_version) == saStatus.saNoError) return new string(firmware_version); return ""; } [DllImport("sa_api.dll", CallingConvention …
Problems capturing BLE advertising packets with SA44B
I’m unable to capture BLE advertising packets using my SA44B. I know my device is advertising because I can see the packets with a passive Bluetooth sniffer. Advertising happens all the time without requiring any external stimulus. I should see spikes on BLE channels 378, 38 and 39 but I see nothing. I assume my …
Understanding SA44B Limitations – Windows/Linux/ARM
Hi Guys I thought I would finally ask this question. I’ve got the SA44B which I am using with a number of computers. For instance windows x64, windows x32, raspberry pi, linux i86 and my latest instalment is trying to get the SA44B APIs to work on an odriod xu4. So I’ve managed to interface …

SA44B Linux 32-bit Linux API files have wrong architecture (64bit)
Hello, I downloaded the Linux 32-bit Linux API files from the support section of your website and tried to compile the provided test program on a 32bit linux machine. The compilation process halts with the following errors: /usr/bin/ld: i386:x86-64 architecture of input file `libSHLAPI.a(main.o)’ is incompatible with i386 output /usr/bin/ld: i386:x86-64 architecture of input file …
Amplitude over reading?
Hello. I have an SA44b and it is over-reading amplitude by approx 2dB. This seems to have started when I installed Spike version 22, although I am not sure of this. An input of (say) -10dBm from my Marconi 2024 signal generator reads only -8dBm and the same 2dB error is displayed at all amplitudes …
Help me: problem with SA44B
Hi everybody, I have a problem with the SA44B spectrum analyzer. Last time, it is run well. But today I saw no data on the SA44B screen or Spike software. I attach an image about this problem, please help me to solve. It is seem that the SA44B run, The SWP on the right bottom …
How to change from "Measuring Receiver" to "FM Modulation Analysys"
I am making an application that uses SA44B in LabVIEW. We want equipped with the same function as the “Measuring Receiver” of the Signal Hound Ver2.18D of application. I want the measurement value is five below. 1.RFCounter; // RF frequency count out (Hz) 2.FMAudioFreq; // AF frequency count out after FM demod (Hz) 3.FMPeakPlus; // …
Measuring DC power supply spectrum
Is it save to use the SA44B together with the DC blocker and an attenuator to measure a 12V DC power supply with a load to see the RF spectrum between 30MHz and 1GHz caused by improper DC switcher and PCB design?
