UVA-1280

The UVA-1280 is a 128 channel arbitrary waveform generator board designed for driving piezo and MEMS devices. The UVA can be connected to a PC via the parallel port, or to any compute via RS-232 or ethernet.

Alternatively, the board has a very simple digital interface that permits it to be placed directly on the databus of a micro-controller. Full specifications for this interface are provided.

UVA Customizations

The preceding specifications are for the existing model. Should your requirements be similar we can make the following changes:

Extended voltage range (350V max)
Ability to drive greater capacitive load
Increased current drive (120mA peak)
Greater or fewer channels
Analog input to read back the actual output voltage
Redesigned PCB to fit your application or for reduced size

UVA Digital Interface:

The UVA-1280 is controlled via its digital interface bus. The UVA may be directly connected to the bus of a micro-controller, or we can provide the following standard solutions:

Interface Options:

PC Parallel Port
RS-232
10baseT ethernet via with Internet enabled interface

The UVA 16 bit digital interface is via 40 bin ribbon cable. The primary interface signals include : 16 data, 10 address, RW signal, strobe, and RESET.
