    Abstract: A temperature control circuit of an oven controlled crystal oscillator (OCXO) is provided. A first and a second digital potentiometer are correspondingly arranged in a bridge circuit which outputs a voltage to an input terminal of a differential amplifier (OPAMP), wherein the resistance value of the first digital potentiometer is adjustable so as to adjust the temperature of the oven to the peak temperature of the crystal resonator, and the resistance value of the second digital potentiometer is adjustable so as to cancel the temperature gradient of the first digital potentiometer. In the temperature control circuit of OCXO, the heat generation of the heater resistor is controlled by the power transistor based on the control voltage from the differential amplifier.

    Abstract: When a unit containing a fuse is mounted, in response to detection of a potential indicating that the fuse has not been blown by a detection circuit, a current for blowing the fuse is supplied from a blowing circuit to the mounted unit containing the fuse, and operation of the blowing circuit is checked based on potentials detected by the detection circuit before current supply and after current supply, respectively. When a unit containing a non-blown component instead of a fuse is mounted, a current is supplied from the blowing circuit to the mounted unit containing the non-blown component, and operation of the blowing circuit is checked based on potentials detected by the detection circuit before current supply and during current supply, respectively, or potentials detected by the detection circuit before current supply and after current supply, respectively.
