HP / Agilent 85093B RF Electronic Calibration (ECal) Module, 3.5mm

The HP/Agilent 85093B is an RF Electronic Calibration (ECal) Module that delivers NIST-traceable calibrations across 300 kHz to 9 GHz using single-connection electronic calibration. Unlike mechanical methods, the 85093B eliminates connector wear, reduces manual intervention, and maintains repeatable accuracy through stored S-parameter data. Its precision 3.5mm slotless connectors guarantee calibration integrity transfer to your measurement system.
