## Overview

The Keysight EXR608A is a 6 GHz, 8-channel Infiniium EXR-Series mixed-signal oscilloscope. In summary, it is a real-time digital oscilloscope built on the same 100M+ gate CMOS ASIC architecture as the high-performance Infiniium UXR-Series, delivering a 16 GSa/s sample rate on every channel, 10-bit vertical resolution, and an always-on update rate above 200,000 waveforms per second. It consolidates seven instruments — oscilloscope, logic analyzer, protocol analyzer, DVM, counter, AWG, and frequency response analyzer — into one bench instrument.

### What is the Keysight EXR608A used for?

The EXR608A is used to capture, visualize, and characterize fast electronic signals during hardware design, debug, validation, and production test — verifying signal integrity, decoding serial buses, measuring power-supply behavior, and isolating intermittent faults that lower-bandwidth instruments miss.

With 6 GHz of analysis bandwidth across all 8 channels and 100 Mpts of standard memory per channel, the EXR608A suits embedded development, power-electronics analysis, high-speed digital validation, and multi-rail power-integrity work. The standard Fault Hunter expert system runs unattended for up to 48 hours, finding and saving rare glitches, runts, and slow edges for later review.

Grounded in the published specifications, the EXR608A provides a typical 10/90% rise time of 71.7 ps, an ENOB as high as 6.8 at its model bandwidth (and 9.0 at 20 MHz), and a noise floor as low as 971 µV at 50 mV/div. Time-scale accuracy is ±8 ppb initial and intra-channel intrinsic jitter is as low as 118 fsRMS — resolving anomalies that coarser 8-bit instruments cannot, which shortens validation cycles and reduces field failure rates.

The EXR608A aligns with industry physical-layer and compliance workflows — serial data analysis, real-time eye diagrams, jitter decomposition, and standards-based compliance test. Every pre-owned EXR608A that ValueTronics offers is held, powered, and functionally verified by our own technicians in our 20,000 sq ft secure warehouse at our Elgin, Illinois facility — we are not a pass-through broker or drop-shipper. That in-house stocking and verification is what lets us stand behind the condition and measurement performance of this instrument before it ships to your bench.

## Why Engineers Choose the EXR608A

-   Seven instruments in one chassis — scope, logic analyzer, protocol analyzer, DVM, counter, AWG, and frequency response analyzer — reducing bench footprint and calibration overhead.
-   Always-on > 200,000 wfm/s update rate and > 750,000 UI/s eye plotting — capturing roughly 200× more of the signal than legacy general-purpose scopes.
-   10-bit ADC delivering four times the vertical resolution of 8-bit instruments, extendable to 16 bits in high-resolution mode.
-   Fully field-upgradeable (bandwidth, channels 4→8, memory, integrated instruments) with standard Fault Hunter for unattended fault isolation up to 48 hours.

## Compare Other Models in This Series

The Keysight Infiniium EXR-Series is a single family of twelve mixed-signal oscilloscopes spanning 500 MHz to 6 GHz in four- and eight-channel configurations. Every member shares the same UXR-derived ASIC, 16 GSa/s sample rate, 10-bit front end, and seven-in-one integration — what changes across the family is analysis bandwidth and channel count.

Choosing within the series is mostly a question of how fast the signals are and how many you need to see at once: a 500 MHz four-channel unit covers most embedded and power work, while the 6 GHz eight-channel units address high-speed digital and multi-lane serial validation.

Each EXR608A-class sibling below has its own dedicated, condition-priced page, so you can line up the pre-owned EXR608A against neighboring bandwidths and channel counts and step up or down in capability without leaving the EXR line. The selection spans the family’s bandwidth range and both form factors.

For the EXR608A specifically, the figures that most drive the decision are its 6 GHz bandwidth, 8-channel count, and 71.7 ps typical rise time. Remember that probe bandwidth must match the scope — the supplied N2873A is rated to 500 MHz.

Across the full EXR line, bandwidth scales 500 MHz / 1 / 2 / 2.5 / 4 / 6 GHz, each offered in a four-channel “x4A” and an eight-channel “x8A” variant. Higher bandwidths carry shorter rise times and slightly higher noise floors, while ENOB eases from 8.2 at 500 MHz to 6.8 at 6 GHz. Every unit is factory-calibrated to 6 GHz, so bandwidth upgrades are pure license-key unlocks.
