FREQUENCY CIRCULATOR - PRINTED PLATES AND PROGRAMMED SYSTEM

Producer: AVT

Most of the constructors-radioelectronics constructing various radio devices measure the frequencies occurring in them. Such measurement, however, is burdened with an error resulting from the lack of calibration of the meter-frequency meter. Virtually all of the frequency meters presented in the literature operate on the basis of a reference generator designed on linearized gates and contain accidentally selected (without paying attention to its stability) quartz resonator. The error of such a device can even amount to +/- 3kHz at 10MHz. This can have a significant impact on the readings, making it impossible to even take some measurements.
The frequency calibrator we propose uses a GPS receiver as the source of reference signals. The stability of the obtained pattern is at the level of 200ns, which translates into a 2kHz error for 10MHz.

The device is particularly recommended in amateur and amateur radio studios

Selected parameters:

  • source of the reference signal - GPS receiver
  • two 50om outputs
  • output voltage 0.8V
  • 2 * 16 alphanumeric LCD display
  • signaling of work mode - LED diodes
  • power supply - 12V
  • dimensions of the tile 85x70mm
  • a printed circuit board, programmed layout and documentation in the set
