The N7555A is part of Keysight’s family of value-line electronic calibration (ECal) modules that makes calibration of vector network analyzers fast, easy and accurate. Cut your calibration down to half the time it normally takes using a traditional mechanical cal kit. Simply connect it to your instrument and the firmware does the rest. For greater precision and higher accuracy measurements consider the N44xx and N469x family of ECal products.
The N7555A supports Keysight’s , PNA-X, PNA, ENA, and PXI vector network analyzers and FieldFox handheld analyzers. The N7555A is a 2-port ECal module that supports 3.5 mm connectors. As a value-line product, it makes it cost effective to replace the N7555A than to have it recertified.
The firmware installed on the instrument is used to control the calibration module, making it a fully integrated solution. The calibration code on the instrument communicates via a USB 2.0 micro-interface and simplifies the calibration to a single connection for a full two-port calibrated measurement.
