This subsystem contains commands which provide access to the raw measurement data (data that has not

been transformed into the current display coordinates). The commands, TRAC:DATA and

TRAC:WAT:DATA, allow you to transfer measurement data between the analyzer and an external

Figure 23-1 shows you the position of TRAC:DATA in the data flow. It also illustrates the difference

between data available in the TRACe subsystem and the CALCulate subsystem.

After measurement data is collected, any specified math operations are performed. Data is then

transformed into the specified coordinate system and sent to the display. TRAC:DATA gives you access

to the raw measurement data after math operations have been performed. This data can be either complex

or real. CALC:DATA gives you access to the display data—after the coordinate transformation.

Both TRAC:DATA and CALC:DATA allow you to transfer measurement data from the

analyzer. Only TRAC:DATA, however, allows you to transfer measurement data to the
