The SmartCal MN25408A is a 4-port auto calibration unit covering a frequency range from 300 kHz to 8.5 GHz. The MN25208A currently offers 3 connector options: N(f)-N(f), K(f)-K(f), 3.5 mm(f) - 3.5 mm(f). The MN25408A delivers automatic, fast and error-free calibrations for any ShockLine VNA. The SmartCal automatically powers on via an USB connection and loads calibration kit coefficients from on-board memory into the ShockLine software. The SmartCal is ready to use immediately after detection by the VNA because it doesn't require warm-up.
