Acquisition Data Files (.csv)
The acquisition data fi les have two sections. At the top of the fi le is the following information:
SamplingFrequency - The sampling frequency in Hertz.
NumberSamples - The number of IQ samples in the fi le.
DateTime - When the data was acquired.
Frequency - The center frequency in Hertz.
AcquisitionBandwidth - The acquisition bandwidth Hz.
Following the AcquisitionBandwidth are the data. The data are IQ pairs, in volts.
Groups of settings or results are headed with [some text].
The fi rst thing in the fi le is the measurement name and the date/time when the acquisition was taken.
The fi rst group [Parameters] are global parameters. Measurement Bandwidth in this group is the
measurement bandwidth used by the General Signal Viewing measurements (Spectrum, Amplitude vs.
Time, etc). It also includes some source settings, like Acq BW, Dither, Preamp, and RF Attenuation.
The second group [Parameters] are measurement-speci fi c parameters.
Another group which can occur is [Trace Parameters]. Within this group, there will be a set of parameters,
one for each trace that is currently shown.
Another group is [Results]. These are scalar results for the measurement.
Another group is [Traces]. It has [Trace] groups under it, one for each trace. Each [Trace] group has
some background information about the trace (units, number of points, x scaling, etc), and the trace
points themselves.
Acquisition Data Files (.mat)
The acquisition data fi les saved in MATLAB format contain the following MATLAB variables:
InputCenter - The center frequency in Hertz.
XDelta - The sample period in seconds.
Y - A complex array containing IQ pairs.
InputZoom - Always 1, and indicates complex data.
The MATLAB format used to save acquisition data has the following properties and limitations:
Files are stored in MATLAB Level 5 format.
MATLAB Level 5 fi le size is limited to 2 GB.
