Hello,
I am trying to collect the points from the trace of a spectrum element, and I am using the following method:
For some reason, this method only returns a single value in the array.
Is there any other way to get the traces from the spectrum?
Thanks in advance
Hi Maireke!
I still haven't managed to fix it. I'm still getting the same errors for certain spectrum protocols, while it works fine for others
Hi,
The SpectrumBufferDataResponseMessage is not officially documented, but I found these following properties that could further help to understand what is being returned:
double[] Values: Trace data points
double CenterFrequency: Center Frequency, in Hz
double FrequencySpan: Frequency Span, in Hz
double StartFrequency: Start Frequency, in Hz
double StopFrequency: Stop Frequency, in Hz
double VBW: Video Bandwidth, in Hz
double RBW: Response Bandwidth, in Hz,
double ReferenceScale: Amount of dB per division.
double ReferenceLevel: Reference Level. Unit can be found in AmplitudeUnit
double SweepTime: Sweep Time, in seconds
double InputAttenuation: Input Attenuation, in dB
DateTime Timestamp: Time of trace measurement
string MeasurementPoint: Name of the measurement point on which the trace was measured. empty if not measured on a measurement point
string InputPresetName: // No info available
double PreAmplifier: // No info available
double FirstMixerInput: // No info available
double DetectionMode: // No info available
double ScalarType: // No info available
bool NotCalibrated: // No info available
string AmplitudeUnit: Amplitude units to use for the ReferenceLevel, e.g. dBm, dBmV.
int AmountDivsHor: // No info available
int AmountDivsVer: // No info available
The Spectrum log file could also provide some more information with temporary increasing the log levels.
In case the properties of the SpectrumBufferDataResponseMessage is not giving a better insight of what is being returned, and the Spectrum log file is also not showing any errors, I would suggest to contact the support team to have this further investigated.

Hi Maximiliano.
I’ve used the GetSpectrumBufferDataMessage succesfully in the past, instead of GetSpectrumRTBufferDataMessage. Not sure if that also supports the ‘inline’ option though.
The SpectrumBufferDataResponseMessage also contains many other properties besides the values, such as the start and stop frequency. Maybe you could try to log them, and hopefully this could give more insight into what’s happening.
Hi Tom,
Is there any documentation for the SpectrumBufferDataResponseMessage?
I see that this question has been inactive for some time. Do you still need help with this? If not, could you select the answer (using the ✓ icon) to indicate that no further follow-up is needed?
