The MR20 from Advanced Testing is an ultra-lightweight and compact RF signal generator capable of outputting 20 independent frequencies from 500 kHz to 400 MHz with 10 Hz frequency resolution. It provides excellent frequency stability and phase noise in a convenient battery or AC powered hand-held unit that is ideal for field and lab testing of RF systems. The MR20 uses a frequency control chip that is pre-set at the factory for up to 20 customer specified frequencies. Additional frequency control chips may be purchased from Advanced Testing for increased frequency selection. Output frequencies can be selected individually or in pre-set pairs and output power is controlled with three user selectable attenuation levels of 0dB, 25dB, and 50dB.
