The Keysight 85058E is an economy mechanical calibration kit for precision calibration of 1.85 mm network analyzers operating DC to 67 GHz. This kit characterizes and compensates systematic errors in RF and microwave test equipment, delivering calibrated measurements across the full frequency range. Six calibration standards enable 1-port, 2-port, and TRM (thru-reflect-match) calibrations using both data-based and polynomial models.
