|Marconi 2022 Generator|
|Description||10kHz-1000MHz AM/FM SIGNAL GENERATOR|
1» 2022 is a light-weight easily portable synthesized signal generator. It has a frequency range of 10 kHz to 1000 MHz and provides comprehensive amplitude, frequency and phase modulation facilities. The instrument is designed to cover a wide range of applications in both production and repair of radio equipments. Output frequency is phase locked to an internal or external frequency standard and frequencies up to 1Ü0 MHz can be set to a resolution of 10 Hz, and above that to a resolution of 100 Hz. 2. Front panel operation is carried out by direct entry of required settings via the keyboard. Microprocessor control ensures flexibility, simplicity of use and allows programming by the General Purpose Interface Bus (GPIB). This facility is offered as an optional accessory enabling the instrument to be used both as a manually operated bench mounted instrument or as part of a fully automated test system. 3. Calibrated output levels from -127 dBm to +6 dBm are provided. A choice of ten output level unit combinations can be obtained on the front panel. The r.f. output level can be set to a resolution of U.I dB over the entire output voltage range and features a total cumulative accuracy of better than ±2 dB. Protection against the accidental application of up to 25 W of reverse power is provided by a fast responding relay trip. Modulation 4. Amplitude, frequency and phase modulation can be provided internally or externally. AM depth can be set in 0.5% steps up to 99.5% at carrier frequencies up to 400 MHz. FM is available at all carrier frequencies and provides deviations up to 99.9 kHz. Phase modulation is also available with a range of up to 9.99 radians. * Front panel 5. All data and units selected are visible on a single liquid crystal display. Data is entered on a keyboard that has been designed to be simple and logical to use. Carrier frequency, modulation and r.f. level functions may be incremented or decremented using the t (UP) and Ψ (DOWN) keys. Nonvolatile store and recall facilities are also provided using an electrically alterable read only memory that does not require a battery back-up system. Available accessories include a front panel cover for protecting the instrument in transit, ‘ Second function mode of operation 6. This includes the means of setting the GPIB address, selection of alternative r.f. level calibration units, access to various calibration routines and a facility to aid diagnostic fault finding via the internal instrument bus.
