4.35 FREQUENCY OUT
The Frequency Out block is used to output a value to the frequency output located on the
optional FAX-32 board. For accuracy of the frequency output, the frequency cannot go
below 200 Hz. The full range of the frequency output is from 200 to 20,200 Hz. To use
the frequency as bidirectional reference, set the offset so 10,100 Hz equals zero; then
scale frequency from 20,200 to 200. The INP to the frequency block is user configurable
by P***:FREQUENCY.
