FastAcq Acquisition Powered by exclusive DPX
®
acquisition technology, FastAcq optimizes the instrument
for analysis of dynamic signals and capture of infrequent events
Maximum FastAcq Waveform Capture Rate >200,000 wfms/sec >400,000 wfms/sec
Waveform Database Accumulate Waveform Database providing three-dimensional array of amplitude, time and counts
Sample Acquire sampled values
Peak Detect Captures narrow glitches at all real-time sampling rates
Minimum Peak Detect Pulse Width ≤1 ns 400 ps
Averaging From 2 to 10,000 waveforms included in average
Envelope From 2 to 2x10
9
waveforms included in min-max envelope
Hi-Res Real-time boxcar averaging reduces random noise and increases resolution
FastFrame
™
Acquisition Acquisition memory divided into segments; maximum trigger rate >265,000 waveforms per second.
Time of arrival recorded with each event
