Anritsu 69345A Signal Generator
The Anritsu 69345A has a modulator control input that alters the pick-up of the modulator to control the power level of the RF exit signals. The modulator control signal is received from the PCB A9 PIN Control, where it is developed for the ALC control signal. Amplitude Modulation is accomplished by differing the modulator control signal with the modulation signal. Another type of modulation is accomplished by changing the modulator on and off at a speed dictated by modulation pulse input. The contribution of the pulse modulator is received through connector J4 of PCB pulse generator A6. The modulating pulse signal is additionally directed through the J5 connector to the switched filter assembly.
The following test can be utilized to confirm that the 10 MHz time base is inside its aging specification. The instrument derives its recurrence exactness from an inner 100 MHz crystal oscillator standard. Recurrence precision is received from an inner high-stability 10 MHz crystal oscillator. A natural characteristic of crystal oscillators is the impact of crystal aging inside the initial few days to an extended period. Normally, the crystal oscillator's recurrence increments slightly, then settles to a generally consistent incentive for the remainder of its life.
For the most noteworthy recurrence precision, the user can enable the Anritsu 69345A to warm up until the RF output recurrence has settled. Once settled, the adjustment in the reference oscillator recurrence ought to stay inside the aging rate if: (1) the time base oven is not permitted to cool, (2) the instrument orientation with respect to the earth’s magnetic fields is maintained, (3) the instrument does not maintain any mechanical shock, and (4) the surrounding temperature is held steady.
