Pulse Output

The pulse output circuitry for CAT2 is located on PCA180. The pulse
output is scalable by a factor of 1, 2, 4, 8, 16 and 32 of the input
frequency by selecting the proper switch on SW2. Scaling of the pulse
output may be limited if an analog output is used in conjunction with
the pulse output. The following drawings illustrate typical connections
and switch settings for various pulse output options.
