Spurious and Harmonic suppressionIn all modes of operation the transmitter uses two local oscillators to convert a 100 kHz signal to the outp ut freque nc y. The first inter mediate a nd seco nd inter mediate freque nc y (carrier frequenc y) are filtered to remove mixing products. A low pass filter follows the final power amplifier to remove har mo nics. Modulation limiting circuitsThe DSP circuit controls limiting of the modulation for both analog and digital modes of operation. In the analog mode, the amplitude of the input signal is scaled so the desired deviation level for the signal is achieved. If the maximum scale value is reached at anytime, hard limiting occurs to clip the signal so overdeviation never occurs. In the digital mode, deviation is determined by the data state of the two TTL compatible data inputs. The exciter only recognizes two data states, (1 and 0) which represent one of four possible deviations. The DSP scales the value and never allows overdeviation. Power limiting circuitThe operating power is maintained to +/- 0.5 dB by means of an automatic gain control circuit that continually monitors the power output of the trans mi tter a nd auto ma tically adjusts the gai n to hold power level.

Terminate the RF OUT terminal of the transmitter into a 50-ohm resistive load. Monitor RF Power out with a calibrated RF Wattmeter. The test configuration is shown in Appendix A Figure 1. Record RF power out from wattmeter at both minimum and maximum rated power. Also measure and record DC voltage and current using a calibrated meter at minimum and maximum rated power.

Meter audio level at input terminals. Terminate the transmitter antenna terminal with a 50-ohm resistive load. Sample transmitter RF power output with a deviation monitor. Hold constant audio input level required producing +1.5 kHz frequency deviation at 1000 Hz. Use this level as 0-dB reference level. Repeat at audio frequencies of 100, 200, 300, 500, 2000, 2500, 3000, 3500, 4000, and 5000 Hz. Results: Reference EXHIBIT 3-2 for standard audio board. Deviation Limiter Operation Connect audio generator, with variable output level to transmitter audio input terminals. Terminate the transmitter antenna terminal with a 50-ohm resistive load. Sample RF output with a deviation monitor. Set audio input level to produce 50% modulation (2.5 kHz) at 1 kHz audio frequency. Record the frequency deviation at each audio input level and frequency. Repeat at audio input levels of -6,0, +3, +6, +10, and +16 dB. Repeat each set of measurements for audio frequencies of 300, 600, 1000, and 2500 Hz.
