MODEL 2411B

2MS/s Arbitrary Waveform Generator

Operation Manual 810029-CD

Rev. D

Publication Date: November 2005

The Tegam 2411B is a high resolution 2 MS/s Arbitrary Waveform Generator with

optional Windows® based waveform creation capability. The updated front panel

and the optional WaveWorkTM Pro +. waveform creation software make the 2411B the

easiest way to create and output the waveforms you need. The additional channels

needed for multi-phase applications can be met with a simple connection between

two or more 2411Bs. It’s combination of bench-top and system features, GPIB (option-

al) and RS232 (standard) interfaces and the integrated software which is optional and

runs under Windows make this waveform generator package a versatile tool useful to

create your waveforms for mechanical simulation, engine simulation, medical electron-

ics, modulated sine wave applications and many more applications.
