Highland V660 Time-to-Digital Converter VME Module

MODEL V660
VME 12-CHANNEL
TIME-TO-DIGITAL CONVERTER

12-channel, 32-bit resolution timestamper
Measures time intervals up to 6.71 seconds
Each of 12 channels is independent timestamper
256-sample FIFO memory for each channel
Jitter typically below 75 ps RMS
Includes option of up to 8M RAM for event buffering
32-bit VME module

The V660 is a 12-channel time-to-digital converter used to record the time of occurrence of twelve independent electrical pulse inputs, each independently timestamped and buffered in FIFO memory.

The V660 may be used in streaming timestamp or single-shot event modes. Each channel will timestamp events separate by 150 ns or more.
