MULTISOURCE GENERATORS.
The 2026A and 2026B are multisource signal generators offering as standard two signal sources in one instrument. Up to three sources may be fitted, each of which is a self-contained modulated signal generator. Each source can either be routed to its own individual RF output or switched to the input of an RF combiner network before being fed to a separate combined RF output. Sources in the 2026A cover the frequency range 10 kHz to 2.05 GHz; sources in the 2026B cover the frequency range 10 kHz to 2.51 GHz. An additional RF input is provided to enable the output from an external RF signal generator to be combined with the signals from any or all of the internal sources.
Each signal source can be controlled independently in frequency and level, and each has its own amplitude, frequency, phase, FSK and pulse modulation capability. All parameters can be entered from the front-panel keyboard and a rotary control can be used to adjust most settings. The instrument includes a GPIB interface that allows remote control of all standard signal generator functions except the supply switch.
The instrument is provided with built-in tests specifically for use with two or three combined sources, such as for amplifier and receiver intermodulation tests and receiver selectivity tests. The sources may be locked together and offset in frequency (additionally with a harmonic or sub-harmonic relationship) as well as level.
Microprocessor control ensures that the instrument is flexible and easy to use and allows programming by the General Purpose Interface Bus (GPIB) or RS-232 serial bus. The GPIB is designed to IEEE Standard 488.2 and is a means of sending commands to an instrument, via a data bus, from a remote controller or personal computer. The instrument can therefore be used manually or as part of a fully automated test system.
