Features of Digidata 1440A

The Digidata 1440A has a maximum sampling rate of 250 kHz per channel, with an outstanding total data throughput rate of 4 megasamples per second. Both the inherent digitizer noise and channel crosstalk noise are rated at less than ±1 mV average p-p at 10 kHz, within a ±10 V input range. The front panel is well laid out with sixteen analog input channels and four analog output channels, eight general digital outputs, one dedicated digital output to trigger devices such as oscilloscopes, trigger inputs to start acquisition and to tag data. The back panel has four additional analog instrument telegraph inputs, as well as a DB-25 connector for the digital outputs.  

Designed to support continuous data acquisition within a multitasking operating system, the Digidata 1440A digitizer is fully supported by our AxoScope 10 for Windows and pCLAMP 10 for Windows electrophysiology software.  

With its USB 2.0 interface, you can easily connect the Digidata 1440A to a laptop computer without the need for a peripheral PC card.
