Sync Output: Sine wave in phase with output;
amplitude working into 1 megohm shunted by
100 pF is greater than 1.7 V rms from 4 Hz to 50
kHz, greater than .1 V from 50 kHz to 2 MHz.
Sync Input: Oscillator can be synchronized to
external signal. For 5 V rms input, sync
frequency can be as much as +/-7% away from
set frequency (sync range). Sync range is a linear
function of sync voltage.
--
Hum and Noise: less than 0.01% of output.
