Advanced MATLAB Functions

MATLAB provides advanced data analysis capabilities. The scope of these capabilities is limitless and beyond the intent of this manual to describe; however, Signature ships with a number of example demonstration codes to help get you up and running quickly with MATLAB.

These include several plotting routines that automatically update the plot as the Signature measurement trace changes. One of these functions is called timerplot. This plot is shown side-by-side with an actual screen shot of the same signal taken from the analyzer’s measurement screen.

Figure 6-3.Signature Measurement Trace vs. MATLAB Timerplot

The timerplot function executes a continuously updated, data acquisition routine and creates a plot of the data in real time within a MATLAB plot window.

You can also invoke measurement functions from the MATLAB command line. For example, another one of the measurement functions that will come with Option 40 is channel power. To see the structure of the channel power command, you can use the help function. This is available for all of the MATLAB functions, as well as all of the Option 40 functions. To use this help feature, type: >> help command name

MATLAB also has a Windows-style help system, which you can get to by using F1 or the drop-down help menu.
