Agilent/Keysight MXR104A

The Agilent/Keysight MXR104A is a 1 GHz, 4-channel real-time oscilloscope built on ASIC technology from the Infiniium UXR-Series. This discontinued but supported instrument delivers deep signal insight and high-performance measurements for complex design validation. The MXR104A integrates eight measurement instruments in a single platform, eliminating the need for separate benchtop equipment.

– Key Features

The integrated 8-in-1 instrument set includes oscilloscope, 16-channel logic analyzer, optional protocol analyzer, 4-digit DVM, 10-digit counter, real-time spectrum analyzer (RTSA with up to 320 MHz analysis bandwidth), 50 MHz waveform generator, and optional Bode plotter. The RTSA supports phase-coherent analysis across up to 8 channels with frequency span options from 40 MHz to 320 MHz, independent of oscilloscope bandwidth via Frequency Extension options.

The 15.6-inch capacitive touchscreen with full HD resolution supports dual independent display via VGA and DisplayPort. Windows 10 operating system with Keysight I/O libraries suite enables remote control via LAN, USB 3.0, and network connectivity for data sharing and instrument automation.

– Upgradeability

The MXR104A supports bandwidth and channel upgrades to adapt to evolving test requirements without hardware replacement.
