This precision device converts standard R/C servo style PPC signals
to an analog DC output with12 bit resolution. The output is stable with input
changes such as: supply voltage, pulse amplitude, frequency and temperature.
Programable options include: output scaling within 0 to 5 volts, positive or
negative going, valid pulse width cut off points, and a second order filter for
different time constants (T/C) output filter rates. All programs are factory set.
