RIGA Event Timer A032-ET Riga A032-ET in Graz

RIGA Event Timer A032-ET Eastbourne, October 2005  Graz uses routinely the Graz E.T. (Dassault Modules)  3.5 ps RMS / TI; < 2.5 ps non-linearity, 2.5 kHz max;  Very good reliability; 5 years of operation now,  Additionally, the new A032-ET from Riga now in Graz:  10 kHz  Very useful in Graz for:  Backup; additonal timing channel;  Continuous control / verification of both ET‘s;  In Progress: Measure Return Energy of each Return (via TI between comp./uncomp. C-SPAD output)

RIGA A032-ET vs. Graz E.T.: CAL Eastbourne, October 2005  Most important: Excellent Linearity of BOTH ET‘s !!!  Deviations within 1-2 ps;  In TI‘s from 100 ns (CAL:140 ns) to 150 ms (GPS)  RMS Values: Riga: < 8 ps; Graz E.T.: < 3.5 ps; that means for the Complete SLR System in a Standard CALIBRATION:  CAL RMS = ps / 2.1 – 2.3 mm (with Graz E.T.)  CAL RMS = 17 – 18 ps / 2.6 – 2.7 mm (with Riga ET)  Both with standard setup, 2.2 Sigma Iteration etc...

RIGA A032-ET Test Results Non-Linearity: < 1 ps; fits perfectly also to Graz E.T.

RIGA A032-ET Test Results Warm-Up, 4.4 h Stability Test: < 1 ps drift after WA; Each dot: Mean of 900 Measurements
