Firmware for Real-Time Signal Peak Detection,
Time-to-Digital Conversion and Analysis
U1084A-TDC
• Single-channel sampling and processing at up to
4 GS/s, on either input ¹
• Effective acquisition length of 580 KSamples per channel
• Peak interpolation with time resolution down to 1/16th
of the sampling period
• Programmable on-board TDC histogram creation with
up to 4 billion counts per bin, peak count or summed
amplitude
The U1084A peak detection and analysis firmware (U1084A-
TDC option) allows real-time acquisition and peak detection
at up to 4 GS/s (down to 488.28 kS/s with binary sparsing).
The firmware enables the creation of a histogram of peak
position versus time for successive acquisitions, the
histogram bins containing peak counts or summed peak
amplitudes.
A large FIFO is used to provide a peak overflow protection:
In the event that a burst of peaks causes congestion in the
data flow, none of the previously acquired data is lost.
Large memory, high throughput
With 580 KSamples of peak analysis memory, the acquired
peak data can be transferred to the host PC at up to
130 Mbins/s, with each time bin as 32 bits.
1) U1084A-TDC firmware does not support synchronous dual-channel sampling.
