I'm using SignalExpress 1.1.0 in an evaluation purpose (evaluation mode valid till July 28th), before purchasing NI acquisition hardware... and maybe software.
When exporting data ("Save to ASCII" step), time axis will display erroneously :
- in absolute time mode : each sample is dated in absolute time (time elapsed since 12:00am Jan 1st, 1904). But data is exported in scientific notation and only 11 characters. Current time is "3.204782e+9". Not enough significant numbers are displayed, thus the time column displays the same value for all samples, being perfectly useless. I couldn't figure out where to increase the number of characters in exported data.
- in relative time mode : each sample is dated in relative time since the beginning of each run. If acquisition is configured to read continuously 10 samples at 10Hz, the "time" column loops continuously from 0.000s to 0.900s, in 100ms steps. Of course, you can reconstruct a true "relative time" column in another software after exporting data, but it would be more logical to date all samples realtively to the very first sample acquired, instead of looping continuously.
Any help or advice would be appreciated, in order to confirm if SignalExpress will fulfill my needs or not.
