a high-precision measurement instrument designed for detecting ultra-low currents and extremely high resistances with unmatched accuracy. It provides 0.01 fA (0.01 \u00d7 10\u207b\u00b9\u2075 A) resolution and measures resistances up to 10 P\u03a9 (10 \u00d7 10\u00b9\u2075 \u03a9) using its integrated 1000 V voltage source.<\/p>\n<p data-start=\"903\" data-end=\"1227\">Equipped with a 4.3-inch color LCD display, the B2985C allows real-time graphical visualization of trend charts, histograms, and numeric data directly on the instrument. This eliminates the need for a PC during analysis, enabling engineers to observe signal stability, noise levels, and transient behavior immediately.<\/p>\n<p data-start=\"1229\" data-end=\"1458\">The Setup Integrity Checker software enhances diagnostic capability by identifying external noise sources through cable and fixture comparison. This ensures precise and stable measurements, even in challenging environments.<\/p>\n<p data-start=\"1460\" data-end=\"1699\">With its combination of precision, speed, and usability, the Keysight B2985C is an essential tool for semiconductor testing, material research, and insulation characterization applications that demand extreme sensitivity and consistency.<\/p>\n<h3 data-start=\"1706\" data-end=\"1738\">Measurement Capabilities<\/h3>\n<ul data-start=\"1739\" data-end=\"2156\">\n<li data-start=\"1739\" data-end=\"1826\">\n<p data-start=\"1741\" data-end=\"1826\">0.01 fA minimum current resolution for ultra-sensitive low-current measurements<\/p>\n<\/li>\n<li data-start=\"1827\" data-end=\"1903\">\n<p data-start=\"1829\" data-end=\"1903\">Up to 10 P\u03a9 resistance measurement with integrated 1000 V source<\/p>\n<\/li>\n<li data-start=\"1904\" data-end=\"1978\">\n<p data-start=\"1906\" data-end=\"1978\">20,000 readings per second for rapid data acquisition and analysis<\/p>\n<\/li>\n<li data-start=\"1979\" data-end=\"2066\">\n<p data-start=\"1981\" data-end=\"2066\">Stable and repeatable performance for long-duration and high-impedance measurements<\/p>\n<\/li>\n<li data-start=\"2067\" data-end=\"2156\">\n<p data-start=\"2069\" data-end=\"2156\">Accurate current, voltage, charge, and resistance readings within a single instrument<\/p>\n<\/li>\n<\/ul>\n<h3 data-start=\"2163\" data-end=\"2183\">Key Features<\/h3>\n<ul data-start=\"2184\" data-end=\"2778\">\n<li data-start=\"2184\" data-end=\"2292\">\n<p data-start=\"2186\" data-end=\"2292\">4.3-inch graphical LCD interface for real-time data visualization (trends, histograms, numeric view)<\/p>\n<\/li>\n<li data-start=\"2293\" data-end=\"2400\">\n<p data-start=\"2295\" data-end=\"2400\">Setup Integrity Checker software for identifying noise sources and improving test setup reliability<\/p>\n<\/li>\n<li data-start=\"2401\" data-end=\"2473\">\n<p data-start=\"2403\" data-end=\"2473\">Auto navigation system for intuitive operation and configuration<\/p>\n<\/li>\n<li data-start=\"2474\" data-end=\"2548\">\n<p data-start=\"2476\" data-end=\"2548\">Fast data logging and trend tracking directly from the front panel<\/p>\n<\/li>\n<li data-start=\"2549\" data-end=\"2616\">\n<p data-start=\"2551\" data-end=\"2616\">High-speed measurement capability (up to 20,000 readings\/s)<\/p>\n<\/li>\n<li data-start=\"2617\" data-end=\"2697\">\n<p data-start=\"2619\" data-end=\"2697\">Compact, durable design ideal for laboratory and production environments<\/p>\n<\/li>\n<li data-start=\"2698\" data-end=\"2778\">\n<p data-start=\"2700\" data-end=\"2778\">Supports USB, GPIB, and LAN interfaces for automated measurement systems<\/p>\n<\/li>\n<\/ul>\n<h3 data-start=\"2785\" data-end=\"2805\">Applications<\/h3>\n<ul>\n<li data-start=\"2806\" data-end=\"2873\">\n<p data-start=\"2808\" data-end=\"2873\">Semiconductor leakage current and insulation resistance testing<\/p>\n<\/li>\n<li data-start=\"2874\" data-end=\"2951\">\n<p data-start=\"2876\" data-end=\"2951\">High-resistance material characterization and surface insulation analysis<\/p>\n<\/li>\n<li data-start=\"2952\" data-end=\"3029\">\n<p data-start=\"2954\" data-end=\"3029\">Precision low-current measurement in nanoelectronics and quantum research<\/p>\n<\/li>\n<li data-start=\"3030\" data-end=\"3091\">\n<p data-start=\"3032\" data-end=\"3091\">Validation and calibration of ultra-sensitive instruments<\/p>\n<\/li>\n<li data-start=\"3094\" data-end=\"3154\">Long-term monitoring of high-impedance devices and systems<\/li>\n<\/ul>\n<p><strong>Note: This is a replacement product for the <a href=\"https:\/\/techmaster.com.vn\/keysight-b2985c-may-do-dien-tro\/\">Keysight B2985C M\u00e1y \u0111o \u0111i\u1ec7n tr\u1edf<\/a><\/strong><\/p>\n<div class=\"tm-en-blocks\"><\/div>\n<div class=\"kx\">\n<div class=\"block\">\n<div class=\"eyebrow\">Specifications<\/div>\n<h2 id=\"specs-b2985c\">Keysight B2985C specifications<\/h2>\n<table>\n<tr>\n<th>DC voltage<\/th>\n<td>1000 V<\/td>\n<\/tr>\n<tr>\n<th>Minimum current measurement resolution<\/th>\n<td>0.01 fA<\/td>\n<\/tr>\n<tr>\n<th>Battery options<\/th>\n<td>N\/A<\/td>\n<\/tr>\n<tr>\n<th>Maximum measurable resistance<\/th>\n<td>10 P\u03a9<\/td>\n<\/tr>\n<tr>\n<th>Charge measurement<\/th>\n<td>Available<\/td>\n<\/tr>\n<\/table>\n<p style=\"font-size:13px;color:#5b6b80\">Source: official Keysight product page (https:\/\/www.keysight.com\/us\/en\/product\/B2985C\/electrometer-high-resistance-meter-0-01-fa.html)<\/p>\n<\/div>\n<\/div>\n<div class=\"kx\">\n<div class=\"block faq\">\n<div class=\"eyebrow\">Frequently asked questions<\/div>\n<h2 id=\"faq-b2985c\">Keysight B2985C \u2014 frequently asked questions<\/h2>\n<details>\n<summary>Where can I buy a genuine Keysight B2985C in Vietnam?<\/summary>\n<div class=\"a\">Techmaster Electronics is an authorised Keysight Technologies distributor in Vietnam.
