Model 902 Phase Locked Oscillator


Now there is an alternative to the unstable crystal oscillator chain that drifts constantly. The Model 902 allows precise receiver/transmitter frequency control using a stable external 10 MHz reference oscillator like a TCXO, Oven Controlled Oscillator or a Rubidium Oscillator.

The Model 902 outputs one of 8 selectable frequencies listed in Table 1 to provide Local Oscillator frequencies for the follow IF frequency ranges - 144MHz, 50MHz, 28MHz and 14MHz.
