GENERAL DESCRIPTION
(3) OUTPUT VOLT AGE VARIATION DUE TO AMBIENT TEMPERATURE.
A thermistor is used to control the oscillating voltage.
Care should be excessive temperature variation because the thermistor is normally
affected by ambient temperature variation.
(4) IMPEDANCE MATCHING.
Any related equipment to be connected to OUTPUT BNC should be checked to see that
its input impedance matches the output impedance A0-3001C(600Q or50Q)
