Agilent | Direct I/O: 33220A/33250A Output a Modulated Signal Read Me

This sample program makes the 33220A/33250A output a modulated signal.

Date: April 2005

Version: 1.0

Language: Agilent VEE Pro 7.5 (or later)

Instruments: Function Generator

OS Requirements: Microsoft® Windows® 2000 or XP

Additional Software: Agilent IO Libraries 14.0 (or later)

This sample program makes the 33220A/33250A outputs a modulated signal.

The modulation depth "ModDepth" can be modified here, as well as the delay between measurements "MeasurementDelay".

Note as well that "ModDepth" is given in percentage terms, therefore, 0 < ModDepth < 100.

A display has been added to allow you to visualize the signal generated, but the best is to connect the 33220A/33250A output to an oscilloscope to see the influence of the modulation depth on the output signal.

If you have installed VEE, you can open the sample program by double-clicking on it or by using VEE's File > Open or File > Open Example menu items. To utilize VEE's Instrument Manager's "Load Sample" capabilities with the sample program, copy the sample program and the .xml file (with the same name as the VEE sample program) into the following directory:
