Keysight Infiniium MXR-Series Oscilloscope

Keysight’s Infiniium MXR scopes feature up to 8 analog inputs

  • It has been a long time since Keysight Technologies introduced a brand new family of scopes to the market. Last year, the American manufacturer did announce some evolutions to its entry-level InfiniiVision 1000 X-Series family as well as the extension to 110 GHz of the frequency band of its UXR series oscilloscopes, very high-end instruments dedicated to niche applications.
  • With the announcement of the Infiniium MXR family, Keysight is setting the pace in the small world of oscilloscopes, tackling the heart of the market and electronic test applications, and following in the footsteps of its competitors Tektronix and Teledyne Lecroy, who launched devices with more than four analog inputs in 2019.
  • The Infiniium MXR_Series consists of various models with 4 to 8 analog inputs with a bandwidth from 500MHz to 6 GHz. The number of channels as well as the bandwidth are upgradable.

As a reminder, Tektronix MSO Series 4, 5 and 6 oscilloscopes are equipped with 4 or 8 analog inputs, depending on the version, each of which can accommodate a probe with 8 digital channels. The WaveRunner 8000HD model is equipped with 8 inputs digitized on 12 bits.

The Infiniium MXR family of oscilloscopes is composed of models with bandwidths ranging from 500 MHz to 6 GHz, depending on the model. This bandwidth can be extended after purchase, as also offered by Tektronix or Rohde & Schwarz with its R&S RTP high-performance oscilloscope.

The Infiniium MXR oscilloscopes have 4 or 8 channels with optional digital inputs. Their analog signal sampling rate can be up to 16 GS/s on eight channels. Standard memory capacity is 200 Mpts per channel. Each channel has an analog-to-digital converter with 10-bit resolution.

These scopes are equipped with a 15.6-inch 1920×1080 Full HD resolution display, providing ample space to view the waveform of signals in both the time domain and frequency domain. They incorporate a spectral analysis function that can be activated from the front panel via a dedicated control knob. Called RTSA (Real Time Spectrum Analyzer), according to Keysight, this function makes it possible to display the spectrum of digitized signals in the frequency domain and in real time, thanks to an FFT overlapping process and a high-speed memory.

These oscilloscopes also have the Fault Hunter function, which, by learning a combination of signals, makes it possible to locate certain anomalies (glitchs, slow edges, runts, etc.) in just two clicks.

These devices include eight instruments: a digital oscilloscope, a logic analyzer (16 inputs, 8 GS/s), a protocol analyzer, a 4-digit digital voltmeter, a 10-digit counter, a signal generator (50 MHz), a frequency response analyzer (50 MHz, magnitute and phase), and a real-time spectrum analyzer (320 MHz span).

Using the PathWave Infiniium software, data can be viewed and analyzed remotely from a PC in the same way as on the oscilloscope. The data can also be shared among several collaborators.
