Low-noise Data Acquisition System
Molecular Devices presents our latest Digidata 1440A digitizer for low-noise experiments.
This high-resolution 16-bit data acquisition system is self-contained and communicates with the host computer
via a USB 2.0 interface, which means extremely easy installation and setup. Designed for ease-of-use and fast
results, the Digidata 1440A comes with versatile AxoScope for Windows software and is ready to take data
immediately after installation. Absolutely no programming is necessary.
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.
AxoScope
AxoScope is turn-key data acquisition and analysis software for Windows, designed to
replace oscilloscopes, chart recorders, and FM tape recorders. AxoScope provides up to sixteen channels of
analog acquisition and four different acquisition modes. Acquire data continuously in Gap-Free mode with
simultaneous display, at up to the speed of the digitizer. Set a trigger threshold for the Fixed-Length Events,
Variable-Length Events or High-Speed Oscilloscope modes. Tag and add comments to the data in real time.
Set analog output holding values. Open Axon-format ABF data files and quickly analyze sections of interest
with an array of browsing and basic analysis tools. Preview data and page layout before printing. Additional
features include voice tags, which allow tagging of data with spoken comments (requires a microphone and sound
card), low-pass and high-pass digital filtering of incoming data, and Store Trace, which freezes a snapshot
of a waveform on the screen for comparison with subsequent input.
