PM1000: Download-while-record; pre-trigger data ratio; LAN

The PM1000 polarimeter can now record unlimited new data while a host continuously downloads already recorded data: A transmission fiber can be monitored 24/365 for polarization events exceeding a defined trigger speed. Download starts as trigger events occur. No event can be missed as long as the huge 64M buffer memory is not exceeded. This corresponds to, say, 1024 lightning strikes with 64K samples each, occuring in minimum time.

Pre-trigger data ratio of PM1000 can be chosen as 50%, 25% or 12.5%.

100 Mbit/s LAN is now available for PM1000, in addition to USB and SPI, just as for Novoptel's other products.
