Key Features & Specifications

The Keysight ESA-E series spectrum analyzers provide best-in-class general purpose spectrum analysis with built-in, one button, distance to fault measurement capability in a mid-priced portable rugged package. This provides enhanced capability to meet your performance goals accurately, easily, and quickly in the most demanding environmental conditions.

Adding the cable fault location personality and a tracking generator (Option 1DN or 1DQ) turns your general purpose ESA-E series spectrum analyzer into a cable fault detection tool. Quickly determining the location of a cable fault can save you hours of fault isolation time.

The personality takes a reflection measurement and performs an FFT over the reflected trace. Results are viewed as fault magnitude versus distance on the display. Manual return loss measurements can also be performed.

This option can be added as a product upgrade.
