Data Sheet
2.3.10.2
Two kinds of test signals may be transmitted by the SCOUT:
– The single pulses are of alternating polarity. One pulse is transmitted in each frame
– The continuous pulses are of alternating polarity. 48 pulses are transmitted in each
2.3.11
The full-bauded pseudo-ternary pulse shaping is achieved with the integrated transmitter
which is realized as a symmetrical current limited voltage source (V
I
The nominal pulse amplitude on the S/T-interface of 750 mV (zero-peak) is adjusted with
external resistors ( see chapter 2.3.13.1).
