The E5080A ENA Vector Network Analyzer covers 9 kHz to 4.5, 6.5, or 9 GHz and is offered in 2-port and 4-port configurations, each supplied with built-in bias tees. The series spans six ordering options (245, 265, 295, 445, 465, and 495) that set the frequency ceiling and port count, all sharing the same Type-N 50 ohm test-port architecture and 12.1-inch touchscreen front panel.

A vector network analyzer characterizes components and networks by measuring how they reflect and transmit signals across frequency, resolving both magnitude and phase of the resulting S-parameters. The E5080A reports corrected system performance in terms of directivity, source match, load match, and reflection and transmission tracking when used with its supported calibration kits and ECal modules, the standard quantities used to qualify reflection and transmission measurements.

ValueTronics stocks its inventory directly from a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois.

Brand Heritage

Keysight Technologies traces its test and measurement heritage to Hewlett-Packard, whose instrument business was spun off as Agilent Technologies in 1999. Agilent's electronic measurement group was then established as Keysight Technologies in 2014, the name under which this product is issued.

Compare Other Models in This Series

The E5080A ENA series is offered as a set of options that differ in two dimensions: the upper frequency limit (4.5, 6.5, or 9 GHz) and the number of test ports (2-port or 4-port), with bias tees included on every option. All variants share the same Type-N 50 ohm test ports, 12.1-inch WXGA touchscreen, selectable 1 Hz to 1.5 MHz IF bandwidth, and the same source and receiver architecture.

Each model below links to its own product page. The option suffix encodes the configuration directly: the first digit indicates port count (2 or 4) and the trailing digits indicate the frequency tier, so option selection maps cleanly to the frequency reach and channel count the application requires.

Each pre-owned model below is its own dedicated product page with condition-matched pricing. Select the option that matches the frequency range, port count, and configuration you need, then choose the listing for your preferred condition.

The options divide along frequency and port count: options 245/265/295 are 2-port test sets reaching 4.5, 6.5, and 9 GHz respectively, while options 445/465/495 are the corresponding 4-port test sets. The 2-port options have a net weight of 20.3 kg and the 4-port options 22.7 kg, with line power consumption of 135 W for 2-port and 165 W for 4-port configurations.

Refer to the comparison table for the per-option frequency range and port count. The Option 1E5 high-stability oven reference (+/-0.45 ppm) is an add-on that can apply across the configurations and is separate from the base frequency and port-count selection.

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.

Product Core & Specifications

Important: Test port damage level: +27 dBm or +/-35 VDC.

Important: Transmission/reflection uncertainty and dynamic accuracy specifications apply to units with serial number prefix MY552/SG552 and above. Units with serial number MY551/SG551 and below require a recalibration with TME N7842A E.05.00 and above.

Important: A third-wire ground is required for the AC line power connection.

Important: Calibration of the E5080A is performed using a separate calibration kit or ECal module (this data sheet specifies the 85032F and 85033E calibration kits and the 85092C and 85093C ECal modules); these are not part of the analyzer and must be ordered separately to make corrected (error-corrected) measurements.

Important: Test port output power level accuracy can be improved by performing power calibration using an external power meter.

Recommended pairing: the E5092A Configurable Multiport Test Set (50 MHz to 20 GHz, 38 test ports) connects to the E5080A over USB to extend measurements to multiport configurations.
