Infiniium EXR-Series Oscilloscope \u2013 2.5 GHz, 8 Channels: Precision, Speed, and Flexibility<\/p>\n<p data-start=\"332\" data-end=\"620\">The Keysight EXR258A belongs to the Infiniium EXR-Series. It is designed for advanced measurement applications in electronics, telecommunications, and automotive industries. With 2.5 GHz bandwidth on all 8 analog channels, it enables accurate multi-channel signal observation.<\/p>\n<p data-start=\"622\" data-end=\"937\">This model integrates eight instruments in one. It includes an oscilloscope, digital voltmeter, waveform generator, spectrum analyzer, mask test, jitter analysis, and serial protocol decoding. Powered by hardware-accelerated ASIC technology, the EXR258A delivers faster test speeds and smoother performance.<\/p>\n<p data-start=\"939\" data-end=\"1248\">The scope provides up to 16-bit vertical resolution in high-res mode and ENOB of 9.0. It offers low noise as little as 43 \u00b5V, ensuring precise signal measurements even under challenging conditions. With flexible memory up to 1.6 Gpts, the EXR258A can record long-duration signals without loss.<\/p>\n<p data-start=\"1250\" data-end=\"1405\">Keysight EXR258A Infiniium EXR-Series Oscilloscope is fully upgradeable, including both bandwidth and channel count, making it a future-ready investment for growing labs and R&amp;D teams.<\/p>\n<p>What&#8217;s Included:<\/p>\n<ul>\n<li>One N2873A 500-MHz passive probe per channel<\/li>\n<li>Probe accessory pouch<\/li>\n<li>Localized power cord<\/li>\n<li>Front panel hard cover<\/li>\n<li>BNC calibration cable<\/li>\n<li>Keyboard and mouse<\/li>\n<li>Keysight I\/O libraries suite, user guide and programmer\u2019s guide ship on oscilloscope drive<\/li>\n<li>1 year factory calibration certificate<\/li>\n<li>Service guide available on Keysight.com<\/li>\n<\/ul>\n<div class=\"tm-en-blocks\"><\/div>\n<div class=\"kx\">\n<div class=\"block\">\n<div class=\"eyebrow\">Applications<\/div>\n<h2 id=\"apps-exr258a\">What is the Keysight EXR258A used for?<\/h2>\n<div class=\"cards c3\">\n<div class=\"card\">\n<div class=\"i\">\ud83d\udd2c<\/div>\n<h3>Design and R&amp;D measurement<\/h3>\n<\/div>\n<div class=\"card\">\n<div class=\"i\">\ud83c\udfed<\/div>\n<h3>Production test and maintenance<\/h3>\n<\/div>\n<div class=\"card\">\n<div class=\"i\">\ud83d\udcc8<\/div>\n<h3>Analog and digital waveform analysis<\/h3>\n<\/div>\n<\/div>\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-exr258a\">Keysight EXR258A \u2014 frequently asked questions<\/h2>\n<details>\n<summary>Where can I buy a genuine Keysight EXR258A in Vietnam?<\/summary>\n<div class=\"a\">Techmaster Electronics is an authorised Keysight Technologies distributor in Vietnam.
