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: < 8 ps RMS / TI; < 0.5 ps non-linearity, > 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 = 14 - 15 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.
