Vector network analyzers (VNAs) have become mainstream due to their comprehensive measurement capabilities, while scalar or handheld devices are more advantageous in cost-sensitive or mobile scenarios. Specialty types (e.g. non-linear or balanced) are designed for specific technical challenges.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>YesterTech offers a family of five different types of network analyzers, ranging from high-end to compact:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Our high-end PNA series excels in measurement integrity and repeatability. The PNA-X offers exceptionally high measurement flexibility and can replace an entire rack of equipment. The overall performance of the PNA is even higher.\u00a0\u00a0<\/li>\n\n\n\n<li>Our mid-range and economical ENA series reduces test costs while providing reliable measurements, an intuitive user interface, and scalable instruments. The ENA balances speed, performance and budget.<\/li>\n\n\n\n<li>FieldFox is the more versatile handheld analyzer. Not only are our handheld VNAs rugged and durable, but they also measure accurately compared to benchtop analyzers.<\/li>\n\n\n\n<li>Modular PXI VNAs save test space. You can customize only the network analyzer features you need and make fast, accurate multiport measurements.<\/li>\n\n\n\n<li>The Lite Series USB VNAs are compact in form, but not in performance. The Lite Series USB VNAs have all the performance of a benchtop instrument in a fraction of the size.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>\u7f51\u7edc\u5206\u6790\u4eea\u662f\u7528\u4e8e\u6d4b\u91cf\u5c04\u9891\u548c\u5fae\u6ce2\u5668\u4ef6\u6027\u80fd\u7684\u5173\u952e\u4eea\u5668\uff0c\u5176\u7c7b\u578b\u53ef\u6839\u636e\u4e0d\u540c\u6807\u51c6\u5206\u7c7b\u5982\u4e0b\uff1a \u4e00\u3001\u6309\u6d4b\u91cf\u53c2\u6570\u5206\u7c7b \u4e8c\u3001\u6309\u9891 [&hellip;]<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"themepark_post_bcolor":"#f5f5f5","themepark_post_width":"1022px","themepark_post_img":"","themepark_post_img_po":"left","themepark_post_img_re":false,"themepark_post_img_cover":false,"themepark_post_img_fixed":false,"themepark_post_hide_title":false,"themepark_post_main_b":"","themepark_post_main_p":100,"themepark_paddingblock":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-11696","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"metadata":{"_edit_lock":["1739499625:1"],"_edit_last":["1"],"catce":["sidebar-widgets4"],"views":["789"],"_trp_automatically_translated_slug_en_US":["\u7f51\u7edc\u5206\u6790\u4eea\u6709\u54ea\u4e9b\u7c7b\u578b"]},"medium_url":false,"thumbnail_url":false,"full_url":false,"_links":{"self":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/posts\/11696","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/comments?post=11696"}],"version-history":[{"count":1,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/posts\/11696\/revisions"}],"predecessor-version":[{"id":11697,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/posts\/11696\/revisions\/11697"}],"wp:attachment":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/media?parent=11696"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/categories?post=11696"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/tags?post=11696"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
