The Axon™ Digidata® 1550 low-noise data acquisition system allows for the parallel patching of up to eight cells simultaneously. It features eight independent analog output channels to simultaneously send command waveforms to multiple cells at one time for higher throughput toxicology experiments or to study synaptic function in complex neuronal networks. Combined with a sampling rate of up to 500 kHz per channel, the Digidata 1550 Digitizer allows researchers to gather more data points in demanding experiments such as nanopore and bilayer studies. This rate monitors signals in the biorelevant frequency range whilst achieving a total data throughput rate of 4 mega-samples per second. Independent analog-to-digital converters for each input channel also ensure low crosstalk levels and high data acquisition rates.
