What is typically included:
• Keysight N7554A ECal module

The Keysight N7554A is part of the N755xA Series of 2-port economy Electronic Calibration (ECal) modules for vector network analyzers. It delivers fast, accurate, and repeatable VNA calibration from DC to 18 GHz, significantly reducing calibration time compared to traditional mechanical calibration kits. The module connects to the host VNA via a USB 2.0 micro-interface; all calibration control is handled by the firmware already installed on the instrument, making it a fully integrated solution with zero wait time.

The N7554A supports a wide range of Keysight VNA platforms including the PNA-X, PNA, ENA, PXI vector network analyzers, and FieldFox handheld analysers. All 2-port ECal modules support in-family mixed connector options (male-male, female-female, and male-female) for the same connector type, simplifying calibration of non-insertable devices.
