AWG2021 Service Manual
The ECL buffer (10E116) output is connected to the output connector. It must be
terminated with a 50
W
resistor at the receiving side (user side). If this termina-
tion resistor is missing, the signals do not appear at the output connector. The
same is true for the clock output. See Figure 7–4.

Figure 7-4: Output Circuit
The data output signal skew is held to 1 ns, maximum. The rise and fall times
depend on characteristics of the buffer IC, but neither is greater than 1 ns. See
Figure 7–5. Both of these maximum levels are the values without using cables. If
a cable is used, these waveforms have transmission distortion.
