The 360 network analyzer is the control and display unit for all versions of the system. Its control (front) panel controls provide menu selections for test functions, test parameters, measurement enhancements, and frequencies. Frequency information is sent to the signal (frequency) source Over a dedicated system GPIB. Test parameters, system status, and measurement data are displayed on the large color screen and hard copied on a printer or plotter. Test sets are available that allow microwave vector measurements-including S parameter measurements of both active and passive devices-frequency conversion measurements, antenna measurements, and receiver measurements. Frequency range is 10 MHz to 40 GHz. Millimeter-wave test sets to 110 GHz are also available. Two signal sources are available 10 MHz to 18 GHz and 10 MHz to 40 GHz. The signal source is controlled by the network analyzer from a dedicated IEEE-488 bus. It provides clean, phase-locked test signals for precise test data. Frequency resolution is 100 kHz. Standard 6600B models are also compatible and could be used in place of the 3608845 and 360SS69 sources.
