This low cost synthesised RF signal generator features a wide amplitude range, low noise and inherently good frequency stability. The generator also features internal and external FM, AM and Phase Modulation. The instrument can be operated manually via the front panel or remotely controlled via the RS232 or GPIB interfaces. It is suitable for radio receiver sensitivity measurements, system gain measurements, oscillator substitutions, EMC/antenna/field strength measurements and as a signal source for many other RF circuit and system development tasks. In addition, the generator's low cost, ease of use and remote control make it eminently suitable for most production and development applications where a basic, stable signal source is required.
