The modulating wave form should have an average poten-
tial of zero volts. Frequency sensitivity, which is approxi-
mately 16 MHzIvolt, is shown graphically in Figure 3-8.
The maximum modulating frequency, while still maintain-
ing the 16 MHzIvolt relationship, varies from approximately
4 kHz at maximum deviation t o 20 kHz for 1 MHz devia-
tion. (See Figure 3-9.) With decreased frequency sensitivity,
frequency up to 200 kHz can be used, as shown in the
shaded area of Figure 3-9 on page 3-1 1.
The peak amplitude of the modulating signal plus the DC
voltage supplied t o the Frequency Control (pin 9 of
REMOTE plug) should not exceed
+
or -16 volts. This
amplitude would program the unit to sweep beyond the
band limits.
