Naming Conventions for Matrix Files
If the destination file is not specified and the /B option is not specified, then the output filenames are
derived from the measurement result names used in the analyzer. The extension .MAT is added. For
example, frequency response data is saved to a file called FREQRESP.MAT. For data which includes
more than one measurement result a separate file is used for each result. For example Histogram data is
saved to HISTOGRA.MAT, PDF.MAT, and CDF.MAT.
If the destination file or the /B option is specified, then the only one result will be converted.
Naming Conventions for Y-axis variables
Within the file, the individual trace data is saved to matrix variables with unique names. The
names are dependent on the channels and the map lines (if there are more than one) that comprise the
trace.
The variable naming format is shown in the following table:
Y-Axis Variable Notes
c<N1>: Where N1 is the channel number for data that is
derived from a single channel or 0 in the case of no
channel.
c<N1>m<N2>: Where N1 is the channel number and N2 is a map
line number in the case of multiple map lines.
o<N1>i<N2>: Where N1 is the output channel number and N2 is the
input channel number for data that is derived from
two channels.
o<N1>i<N2>m<N3>: Where N1 is the output channel number, N2 is the
input channel number, and N3 is a map line number
inthecaseofmultiplemaplines.
Examples of variable names:
Variable File Notes
c2 INSTTIME.MAT Channel 2 of an Instantaneous Time measurement.
c2m3 POWERSPE.MA
T
The third map line in channel 2 of a Power
Spectrum measurement.
o2i1 FREQRESP.MA
T
Output channel 2 versus input channel 1 of a
Frequency Response measurement.
These naming conventions were chosen to ensure that each variable name in the file is unique. You can
change the names in MATRIXx or PC-MATLAB if you wish. For example you can create names which
are easier to remember or which more clearly describe the data.
