Controls & Indicators
The front-panel controls/indicators include:
1. An instrument for displaying the phase difference between the test frequency fx and the standard frequency fy. The full scale is 100 divisions, representing a 21 microsecond phase difference.
2. A switch for setting the frequency fx. The switch position must match the frequency fed into the input to display correctly on the instrument.
3. An input for the frequency fx, which can range from 1 to 10 MHz and must be an integer multiple of 1 MHz. The amplitude should be between 0.1 V and 2 V.
4. An output for connecting a recorder or an instrument with higher resolution, with a voltage range of 0 to 5 V and a maximum current of 5 mA.
5. A fuse for the operating voltage, which should be between 22 V and 32 V.
Installation / Setup
The source does not provide specific information on installation or setup highlights such as wiring, clearances, calibration, or prerequisites.
Operation
The manual provides information on the operation and basic usage steps of the Phasenkomparator. It is used to compare two frequencies and display their phase relationship. One frequency must be a standard or normal frequency of 5 MHz, while the other can be 1 MHz or an integer multiple up to 10 MHz. The device is primarily used for controlling and calibrating quartz oscillators. It operates by deriving impulses from the two frequencies to control a flip-flop, resulting in a square wave signal with a frequency of 500 kHz. The device requires a DC voltage between 22 V and 32 V for operation.
