The Agilent E5100A is a network analyzer covering 10 kHz to 300 MHz, integrating a signal source and a receiver in a single instrument. It supports one to four measurement channels and performs both magnitude and phase measurements, with measurement calibration types including response, response and isolation, and 1-port 3-term.

A network analyzer characterizes how a device behaves across frequency by comparing a stimulus signal against the device's response. The E5100A offers ratio measurement modes such as A/R, R/A, and, with the appropriate input configuration, B/R, B/A, A/B, and additional pairings, alongside absolute A, B, and R measurements. Both frequency and power sweep parameters are available, using linear (step, ramp) or list sweep types over a Cartesian display format.

ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every used unit is inspected and functionally verified in-house before it ships, while new units leave the warehouse factory-sealed exactly as received. Holding inventory directly means the instrument you order is one we physically have on hand and have prepared to the standard appropriate for its condition.

## Brand Heritage

The test and measurement line carrying the Agilent name originated with Hewlett-Packard, whose test and measurement business was spun out as Agilent Technologies in 1999. That business was subsequently transferred to Keysight Technologies in 2014.
