MOD-16P
Instruments:
1. signal generator: 8903b
2. oscillograph: LS8106
3. modulator: JMM-2200
4: frequency recorder: EFC-3203A
5. DC power supplier: 3303A.
6. multi-meter
7. frequency spectrum: E4403B
Instruments Setting:
1. signal generator: 1kHz/65mV.
2. modulator:
2.1. Tone set: H: Pass: 3K L: Pass: 50K RANGE: 10
2.2. AF set: H: Pass: 25 L: Pass: 15K RANGE: 50
Test procedure and specification:
1. Turn on the power supply (press the ON/OFF key for 2 seconds), the LED indicator
will light up, after the LCD show the battery and frequency status, the bright of LED
indicator will be decreased.
2. Test the sense power of PL2 on CH0, CH50, CH99 are above 5dBm, the sense
power of PL1 is above 2dBm, the sense power of PL0 is above -4.5dBm, and the
harmonics is below -45dBm. (Note: the power of PL1/PL2/PL0 must have obvious
variation)
3. Input signal from MIC input terminal (shout), the modulator will have output.
4. Tone test: Tone signal is in the range of 3KHZ±0.5KHZ, the frequency is in
31~34KHZ.
5. In standard range test the radio frequency, and permit the error in
±2KHZ.
