TEST DATA

3 . 1 RF POWER OUTPUT (FCC Rules Part 80.215 & 2 . 1 0 4 6 )
3 . 1. 1 Method of Measurement
The FS-2570 is connected with measuring equipment as shown in Fig. 3.1.1.
Supply voltage is set to 24 VDC. An ammeter is connected in series with collector of each final
stage transistor. Test is made under normal environmental condition.
2 Audio Signal Generators generating each 400 Hz and 1800 Hz at an equal level are
adjusted to produce transmitter RF output power 250 Wpep. Collector current is then
measured.
Measurement is made on every test f frequency on class of emission J3E.
