And it support for exporting snp files for various radio design and simulation software.         - As a measuring device, accuracy is of great importance. Simple calibration parts are included in the package. We have calibrated the product`s dual ports before delivery. When your measurement conditions change (for example, switching from a narrower calibration bandwidth to a wider measurement bandwidth with an extension cable measurement), you need to re-calibrate. After calibration, it is saved as setting 0, which can be used directly at the next boot, or it can be saved to the other 4 saved items through recall when needed.         ?         \u003cstrong\u003eParameters:\u003c\/strong\u003e   \u003cbr\u003e ?         1.
