Rohde and Schwarz ZV-Z23 Manual Calibration Kit, Type N

The Rohde & Schwarz ZV-Z23 is a TOSM calibration kit engineered for precise vector network analyzer calibration across DC to 26.5 GHz. Designed for 3.5 mm connectors, it delivers the calibration standards required for full two-port and one-port measurement confidence on Rohde & Schwarz network analyzers. This kit includes Through, Open, Short, and Match standards in both male and female configurations, plus two PC 3.5 mm to N male adapters.

The 50 Ω impedance standards span from DC to 26.5 GHz with exceptional phase stability and return loss performance across the band.
