Mix the local oscillator signal and the external test signal to obtain the difference frequency signal, and calculate the external test signal amplitude through the detector. Using a high-precision VCO signal source, the heterodyne signal frequency can be measured very accurately. Because the scanning range is very large (35M-4400M), due to cost reasons, there is no dedicated detection circuit for the external test signal. There may be errors in the measurement amplitude. Therefore, the product has increased the magnification and displacement parameters. The display is adjusted and calibrated.\u003c\/p\u003e\n\n\u003cdiv\u003e\u003cdiv\u003e\u003cimg class=\"detail-desc-decorate-image\" referrerpolicy=\"no-referrer\" slate-data-type=\"image\" src=\"https:\/\/ae01.alicdn.com\/kf\/H534b45bbbb6441639daa8f49c0e5c18eO.jpg\"\u003e\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"detailmodule_text-image\"\u003e\n\u003cp class=\"detail-desc-decorate-title\" style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\"\u003eWhat's in the package\u003c\/p\u003e\n\n\u003cp class=\"detail-desc-decorate-content\" style=\"font-family:OpenSans;font-size:14px;font-weight:300;line-height:20px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\"\u003e1 x Spectrum Analyzer\u003cbr\u003e\n1 x USB cable\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\u003cscript\u003ewindow.adminAccountId=206079709;\u003c\/script\u003e","brand":"Cartoolshop","offers":[{"title":"Default Title","offer_id":47412578943143,"sku":null,"price":150.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0080\/7908\/1562\/files\/H0cb152a38ef949e0a3064e5297797aefo.webp?v=1765362874","url":"https:\/\/www.cartoolshop.com\/products\/new-4-3-inch-display-35mhz-4-4ghz-handheld-spectrum-analyzer-signal-generator-with-tracking-source","provider":"Cartoolshop","version":"1.0","type":"link"}
