Manufacturer's Specifications:

The Wiltron series sweep generators is an all-new generation of solid state sweepers, combining new RF technology with picroprocessor control. This is truly an easy-to-use instrument which is equally well suited to operation from the front panel or as a computer-controlled signal source in an automatic test system. In either application, the improvement in accuracy with which microwave measurements can be made is impressive. Fundamental oscillators generate clean signals with harmonics that are less than -40dBC from 2 to 26.5 GHz, avoiding the errors of harmonic-burdened signal sources. Whether you need a broadband signal source for ATE or for a traditional reflection and transmission loss or gain test setup, the 6600A is your best choice.

GPIB Indicators: When a General Purpose Interface Bus (GPIB). Option 3 is added to the instrument, LED lights indicate the following conditions:

Remote: Operating on GPIB

Talk: Talking on GPIB

Listen: Listening on GPIB

SRQ: Sending a service request

Local Lockout: Disabling the RETURN TO LOCAL pushbutton. The instument can be placed in local mode only via GPIB.
