ANNEX 2 – ETS PERFORMANCE
ETS Performance (L1 Prototype)
Added jitter of High-precision trigger, TTL output, cPCI-EVRTG-300 Here, added jiiter of LVTTL output (EVRTG on-board) is ~14.5ps wrt. RF clock signal.
ETS Performance (L1 Prototype)
Waveform of high-precision trigger, TTL output, cPCI-EVRTG-300 Here, a 10 ns trigger pulse shows voltage level of 3.3V LVTTL output (EVRTG on-board) is ~2.88 Volts at 50 Ohm load.
