Multi-Channel ADC Datalogger Configuration Page


This is the page to configure the LTC 1859 and LTC 2498 ADCs for data logging

The system will sample all the selected channels every [sampleinterval] milliseconds.
ADCs that are too slow to maintain the sampling rate will wait until the next sample clock tick.
The system will stop after [numsamples] samples have been taken per (fastest) channel.
This data will be written to a .csv file with name [logfilename] on the USB flash drive.

There is also the ability to write to the DACs after each round of samples using the Data File.
