75 Ohm Type N VNA Calibration Kits
8880A/B Series Data Sheet 2Z-025 Fixed Termination Kits • 75 Ohm Kit • Simple Fixed Load Calibration Description The 8880 series of calibration kits are designed to calibrate vector network analyzers (VNAs) for 75 ohm type N connector measurements. These kits are designed for calibrating the Agilent 8752B or Agilent 8753C/D (with Agilent 85046B, Agilent 85044B test sets, or Agilent 11850D splitter) 75 ohm VNAs from 300 KHz to 2 GHz. When used with appropriate adapters, they can also be used with 50 ohm VNAs such as the Agilent 8510A/B/C, Agilent 8719, Agilent 8720 and Anritsu 360/37000 series, as well as other network analyzers for making 75 ohm measurements. The connectors utilized are a precision version of type N 75 ohm connectors. A full complement of calibration standards (opens, shorts and fixed terminations, female and male) are provided in the 8880A and 8880B kits. In addition, the 8880B kit is provided with three (3) in-series adapters that are phase-matched for accurate measurements of non-insertable devices. Each kit (components, standards, and customer-specified software media) is housed in a foam-lined wooden instrument case. Operating instructions are included with calibration standard constants so that they can be keyed in from the VNA's front panel. Connector Description The type N 75 ohm connectors provided on the various components in these kits and accessories are a precision version developed by Maury which meets all applicable requirements of IEC169-16. They exhibit extremely low VSWR, and although currently specified to 2 GHz, they can be used at much higher frequencies. Also the male connectors are provided with a 3/4" hex coupling nut so the junctions can be properly torqued to 12 in/lbs (use torque wrench 2698C1). Warning: Do not mate a 75 ohm type N connector to a 50 ohm type N connector.	8880B Equipment Provided in Kit 8880A, basic kit: provides all the calibration standards as follows: 1 ea Fixed termination, type N 75 ohm female 1 ea Fixed termination, type N 75 ohm male 1 ea Fixed short, type N 75 ohm female 1 ea Fixed short, type N 75 ohm male 1 ea Open circuit, type N 75 ohm female 1 ea Open circuit, type N 75 ohm male 1 ea Instrument case 1 ea Operating instructions 8880B, expanded kit: provides all the items in the basic kit plus the following in-series phase matched adapters: 1 ea Adapter, type N 75 ohm female to female 1 ea Adapter, type N 75 ohm male to male 1 ea Adapter, type N 75 ohm female to male
