|Philips PM5326 Generatore|
|Categoria:||Strumenti di misura|
|Descrizione:||RF signal generator|
The RF signal generator PM 5326 is an instrument of high accuracy. The precise specifications and easy to operate controls make this device suitable for service workshops and education as well as development laboratories. The variety of applications includes telecommunication, radio and television problems. Based on the phase-locked-loop (PLL) principle the RF carrier is very stable and easy to be set. The frequency is electronically counted (MOS technique) with X-tal reference and 5-digit LED-displayed. So faults in setting and reading which are characteristic for common generators with circular or linear scales are eliminated. The amplitude of the carrier frequency able to be wobbulated is precise stabilized throughout the whole frequency ranges. Radiation of the internal generated frequencies possibly escaping the case or the mains cable is utmost reduced by the separate cast RF housing within the instrument. So reliable use of the high attenuation can be made. The instrument includes a separate swept frequency oscillator (wobbulator), the ranges of which are optimal suited for the common AM/IF, FM/IF, TV/IF and VHF range as well. The wobbulator is over-more used as frequency modulator for the FM/IF and VHF ranges. Together with the wobbulating ranges the center frequency, the width and marker distance of the spectrum is automatically switched over. When a wobbulating range is chosen, the X-tal controlled adjustable reference carrier frequency is used as "travelling marker" for pointing out the response in the band-pass. The wobbulated or frequency modulated signal is then amplitude stabilised, defined attenuated and fed to the RF output. The multi-variable applications are pre-determined in the extensive push-button array which in conjunction with the further controls, sockets and the display are all arranged at the frontpanel. The text plate is multi-coloured so indicating the different functions for operating convenience. The overall electrical and mechanical concept reduces the time for set-up, measurement and evaluation.
