Note:
The maximum input frequency only stands for the cutoff frequency of the square-wave input at PWM 8
(signal source: frequency generator).

Special feature of TTL interface board:
Owing to the input wiring, the PHA/TV display works properly even in the case of a cable break. The missing
signals are generated internally and output at the encoder output. Cable breaks can be found in the mode
"Measure Signal Amplitudes" or by checking the encoder signals at the BNC sockets.
