HP 85640A Portable Tracking Generator, 300 kHz to 2.9 GHz

The HP 85640A is a MIL-Rugged portable tracking generator to be used with the HP 8560A, 8561A/B, or 8562A/B portable spectrum analyzer.

Combining the HP 85640A tracking generator with a portable spectrum analyzer results in a system having both scalar-analysis and spectrum-analysis capabilities. Use the scalar-analysis capability to perform measurements such as gain, frequency reponse, compression, flatness, and return loss on components and subsystems. Use the spectrum analysis capability to measure harmonic and inter-modulation distortion, as well as spurious products.
