ST805 High Purity Microwave Synthesized Sweeper

it has excellent phase noise, wide frequency coverage, high frequency resolution and accuracy, high output power and wide dynamic range, as well as abundant modulation, program control and frequency expansion functions. The sweeper is mainly used to provide simulation signals for electronic equipment. Besides it can be used to test the dynamic range, sensitivity and selection performance of the receiver. Users can install internal modulation sweepers and external mm-wave frequency expanding modules. The design, together with its friendly user interface and great cost-effectiveness, makes the sweeper a modern intelligent microwave measurement instrument with vast applications in areas including radar, communication and element parameter test.
