I have a question about the pre-triggering possibilities of your devices.
We would like to observe our machine over months (voltages from 5 to 30 Volt) and then when the failures appears, it should be possible to "watch back" for at least 20min (at least 1kS). Is this possible with your devices without generating huge log files ??
Is it also possible to have a oscilloscope or logger with 4 channels and a external trigger ??
Can be set, for each channel, an own trigger condition ??
