FEATURES The 2022C is. a light-weight synthesized signal Generator having a frequency range of 10 kHz to 1 GHz and providing comprehensive amplitude, frequency and phase modulation facilities with an RF output level range of -127 dBm to +13 dBm. It is designed to cover a wide range of RF applications in development, production and maintenance. Output frequency is phase locked to an internal or external frequency standard and frequencies up to 100 MHz can be set to a resolution of 10 Hz, and above that to a resolution of 100 Hz. Fig. 1-1 10 kHz to 1 GHz Signal Generator 2022C 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. Output Calibrated output levels from -127 dBm to +13 dBm are provided. A choice of ten output level unit combinations can be obtained on the front panel. The RF output level can be set to a resolution of 0.1 dB over the entire output voltage range. Protection against the accidental application of up to 50 W of reverse power is provided by a fast responding relay trip. Full protection is also provided when the instrument is switched off. An RF level offset capability allows the output level to be varied relative to the indicated value to compensate for external cable losses or to ensure that all instruments in a particular area give identical results. Modulation Amplitude, frequency and phase modulation can be provided internal or external sources. AM depth can be set in 0.5% steps up to 99.5%, FM deviation up to 99.9 kHz and phase modulation up to 9.99 radians. An auxiliary modulation input allows dual modulation to be applied for receiver testing. Front panel 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 RF level functions may be incremented or decremented using the t (UP) and | (DOWN) keys. Non-volatile store and recall facilities are also provided using an electrically alterable read only memory that does not require a battery back-up system. A front panel cover for protecting the instrument in transit is available as an accessory. Second function mode of operation This enables a number of auxiliary functions such as setting the GPIB address, selection of alternative RF level calibration units, access to various calibration routines and an aid to diagnostic fault finding via the internal instrument bus.
