The Agilent 8645A agile signal generator combines high performance with frequency agility for new fast-switching test requirements. These capabilities are important for performance testing of such devices as frequency agile radios ａnd surveillance receivers. Besides extending traditional receiver testing to agile applications, the Agilent 8645A can be used to create complex signal simulations involving several modulation types ａnd frequency agility. The high performance ａnd frequency agility of the Agilent 8645A provide capability for both static ａnd agile test requirements with just one calibrated signal generator.

• High performance in-channel ａnd adjacent channel measurements, both in static ａnd agile operation
• Simultaneous FM, AM, ａnd pulse modulation
• Maintains signal performance while switching frequencies as fast as 15 microsec from 128 to 2060 MHz
• Flexible control of frequency switching using GPIB from the front panel or TTL connectors from the rear panel
