Notes:
(1). The output rise and fall times of each NECL channel are measured with its complementary output terminated into 50 Ω
/V
otherwise, output waveform distortion and rise time degradation will occur. Use the PRL-ACT-50, Dual Ch. AC-Coupled 50 Ω
Termination, for the 50 Ω /V
attenuator, respectively) for connection of NECL signals to 50 Ω input oscilloscopes.
