3 GHz N Female 50Ω Ohm Calibration Kit for VNAs HP Agilent Network Analyzer

Description

Despite being a precision instrument, a vector network analyzer gets most of its accuracy from the calibration kit. A decent calibration kit is essential for accurate use of a VNA.
Accurate electrical models are needed of the opens and short circuits. A number of eBay sellers sell low-cost calibration kits, but these are effectively useless. This kit is different, in that it is designed, rather than just assembled, it's universal calibrator.
The design of this kit is vastly superior to that of other cheap calibration kits sold on eBay and elsewhere.
Accurate physical measurements, all items will be test again before shipment.
Features of all 2.5~6GHz shows as following, please notice this listing product is only one of following groups, please check listing title:
50Ω 3G Open (N, SMA, TNC): SWR > = 100
50Ω 3G Short (N, SMA, TNC): SWR > = 100
50Ω 3G Load (N, SMA, TNC): SWR < = 1.02
50Ω 6G Open (N, SMA): SWR > = 100
50Ω 6G Short(N, SMA): SWR > = 100
50Ω 6G Load(N, SMA): SWR < = 1.04
75Ω 2.5G Open (N, F): SWR > = 100
75Ω 2.5G Short(N, F): SWR > = 100
75Ω 2.5G Load(N, F): SWR < = 1.02
In summary, this is an economical calibration kit, far below the cost of those from Agilent and similar, and suitable for all amateur and most professional use.
