A modification of a commercially available digital-audio tape (DAT) for DC recordings such as those used in patch clamp and other electrophysiological experiments is introduced. The modified DAT can record data from 2 channels plus a separate trigger signal for up to 2 h. The bandwidth ranges from direct current to 21 kHz; the signal-to-noise ratio is above 90 dB and the A-D resolution is 16 bit. A 120-min cassette yields a storage capacity of 1.4 Gbytes. The trigger is 'hidden' on 1 channel as a burst of 1-ms duration, thus minimizing interference with the recorded data. The modified DAT offers a low-cost yet high quality solution to most analog data storage needs.
介绍了一种对市售数字音频磁带（DAT）的改进方法，用于直流记录，如膜片钳和其他电生理实验中使用的记录。改进后的DAT可以记录来自2个通道的数据以及一个单独的触发信号，最长可达2小时。带宽范围从直流到21kHz；信噪比高于90dB，模数分辨率为16位。一个120分钟的盒式磁带存储容量为1.4GB。触发信号作为持续1毫秒的脉冲串“隐藏”在一个通道上，从而将对记录数据的干扰降至最低。改进后的DAT为大多数模拟数据存储需求提供了一种低成本但高质量的解决方案。
