USB and LAN are on both models; the UTE323G is for GPIB-bus racks.\u003c\/p\u003e\n\u003ch3\u003eDoes each channel measure harmonics?\u003c\/h3\u003e\n\u003cp\u003eYes — per-channel harmonic analysis to the 50th order.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"UNI-T","offers":[{"title":"Default Title","offer_id":53859699851548,"sku":"182700300016X","price":3899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/9208\/0924\/files\/UTE323_1_sq.jpg?v=1770232639","url":"https:\/\/uni-trendus.com\/products\/ute323g","provider":"Uni-Trend US","version":"1.0","type":"link"}
