Many of the loads supplied with lower-cost VNAs are not good quality, yet the VNA is configured to assume the load is perfect. This SMA male load has been individually measured on a calibrated VNA to 8.5 GHz, and the data is on the supplied USB stick as a Touchstone .s1p file.\u003c\/p\u003e\n\u003ch3\u003eThree ways to use it\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVerify.\u003c\/strong\u003e Calibrate as normal, then measure this load and compare the result with the supplied .s1p file.
