USB MI, U2761A function generator
Basic signals and arbitrary waveforms
U2761A USB modular one-channel function generator
The U2761A USB function generator offers eleven standard signals as well as arbitrary waveforms. It relies on direct
digital synthesis (DDS) to create stable, accurate output of low-distortion sine waves. The U2761A also provides square
waves with fast rise and fall times up to 20 MHz and linear ramps up to 200 kHz. For simulation of real-world signals,
use the waveform editor to create arbitrary waveforms with 14-bit resolution up to 200 kHz.
Internal modulation eliminates the need for a separate modulation source. Linear and logarithmic sweeps are also built
in, with sweep rates from 1 ms to 500 s.
With the included IVI-COM drivers, this instrument is compatible with popular development environments. Hi-Speed
USB 2.0 compatibility makes connection to a PC quick and easy.

Accessories
The function generator includes an AC/DC adapter, a USB
Standard-A to Mini-B interface cable and an L-mount kit
(for use in the U2781A chassis). The table presents three
