All Wave Signal Generator
ALL WAVE SIGNAL GENERATOR
Connect instrument to 50 c/s 200-250 volt supply. Switch on and allow two minutes warming up period. By this time the oscillator has reached a stable condition and the instrument is ready for use. Connections to the radio set should be made via a screened lead to the Pye socket on the Signal Generator. The range switch is then set at the appropriate band, the desired frequency is then selected by the main tuning control. Fundamental frequencies are generated on ranges 1 - 5.
Ranges 1 x 2 and 1 x 3 are calibrated as 2nd and 3rd Harmonics of Band 1 respecively, provided receiver under test is tuned to the appropriate frequency, no difficulty should be experienced in selecting the second or third harmonic as desired.
e.g. Receiver under test is tuned to 45 Mc/s. Set range switch to Band 1, 45 Mc/s may then be selected on range 1 x 2 (second harmonic 22.5 Mc/s) or range 1 x 3 third harmonic 15 Mc/s. The output meter is not internally connected. Connect in parallel with speech coil of receiver, under test.
WARNING PLEASE NOTE:-1) KEEP RF CONTROL AS LOW AS POSSIBLE AS OVERLOADING O.P. METER WILL BURN IT OUT. 2) BREAKING OF THE SEAL AT BACK OF THE GENERATOR VOIDS GUARANTEE.
