Example 1
Convert up to 4096 points of your file (GLITCH) to a PC-MATLAB file (GLITCH.MAT); includes
X-axis data points. Note the PC-MATLAB searches for a file with the suffix ‘’.MAT’’ if no suffix is
specified. See appendix for more information on loading a file into PC-MATLAB.
DFDATA63 GLITCH C:GLITCH.MAT /L /X /P:4096
Example 2
Output channel 2 data (THRUPUT) to an ASCII file (THRUPT.ASC) after skipping the first 20480
points of the data file:
DFDATA63 THRUPUT THRUPT.ASC /B:20480 /C:2
Discussion
Each capture/throughput record contains 2048 real points (baseband) or 1024 complex points (zoom). A
capture file contains up to 10 records of time data, whereas a throughput file contains up to 32767
records. Since capture/throughput data can be very long, the /B and /P options can be used to select only
a portion of the data in a file. The /C option only needs to be specified for a 2 channel throughput file to
select channel 2 as the source of data.
An ASCII file contains one line for each data point (up to 3 fields separated by commas). If the /X option
is specified, the first field is the X-axis data value. The next field is the real part of the Y data point. If
the data is complex, then the last field is the imaginary part of the Y data point.
Both the PC-MATLAB and MATRIXx files contain the following matrix variables:
Trace X Vector of X values (only if /X is specified).
Start X Starting X value (only if /X is not specified).
IncrX Linear X increment between points (only if /X is not specified).
LogX Log X increment between points (only if /X is not specified). This value is always
1.0.
TraceData Vector of Y values (may be complex).
If the /X option is not specified, the StartX and IncrX variables can be used to calculate the X data as
follows:
X = (Xlast + IncrX)
where Xlast is the previous point’s X and the first X is StartX.
