Electronic Installation

Maximum Transmission Distance (continued)

The graph below shows the relationship between output capacitance loading and rise and fall time for the
Model 234 output signal. For instance, with 0.04uF load capacitance (1000 ft. shielded cable typ.) the rise/fall
time is 10 uS. Consequently, the absolute maximum frequency the Model 234 could transmit would be 50 kHz
(frequency = 1/time, where time includes the rise and fall times for one cycle).
