Key features

A wide variety of optical, electrical, and accessory modules support your specific testing requirements.

Optical modules

  • Optical modules that support optical data rates from 155 Mb/s to 10 Gb/s to 40 Gb/s to 100 Gb/s to PAM4 for 50G/100G/200G/400G
  • Optical reference receivers (ORR) 1 support specified requirements for standards-mandated compliance testing
  • High optical sensitivity, low noise, and wide dynamic range of the optical sampling modules allows accurate testing and characterization of short-reach to long-haul optical communications standards
  • Fully calibrated clock recovery solutions – no need to manually calibrate for data pick-off losses
  • Calibrated extinction ratio measurements and variable correction ER measurement ensure accuracy and repeatability

Electrical modules

  • Very low-noise electrical samplers (280 μV at 20 GHz, 450 μV at 60 GHz, typical)
  • Selectable bandwidths 2 allow the user to trade-off sampler bandwidth and noise for optimal data acquisition performance
  • Remote samplers or compact sampling extender module cables minimize signal degradation by allowing the sampler to be located in close proximity to the device under test
  • High-performance integrated TDR (10 ps typical step rise time) supports exceptional impedance discontinuity characterization and high dynamic range for S-parameter measurements to 50 GHz


  • Jitter, noise, and BER analysis of high-speed PAM4 and PAM2 NRZ serial data rates from <1 GBd to 60 GBd provides insight into precise causes of eye closure
  • Analysis of PAM4 signals with comprehensive jitter, noise and BER analysis for each individual PAM eye, and a set of global measurements that assess the overall PAM4 signal attributes
  • 100G-SR4/Transmitter and Dispersion Eye Closure (TDEC) automation provides turn-key testing and debug of TX Optical properties key to the SR4 Short Reach Ethernet
  • 80STDEC streamlines high performance Transmitter and Dispersion Eye Closure (TDEC) measurement making it ideal for manufacturing and conformance validation applications
  • Automated mask testing with over 80 industry-standard masks. New masks can be imported into the DSA8300 to support new emerging standards. Users can define their own masks for automated mask testing
  • Jitter, noise, BER, mask testing, and Serial Data Link Analysis (SDLA) are provided through the 80SJNB Essentials and Advanced Software Application Options
  • Advanced TDR analysis, S-parameter measurements, simulation model extraction, and serial link simulation capabilities are provided by the IConnect® Software Application options
  • 400G-M4 Optical Manufacturing Analysis Software provides Optical Transmitter and Dispersion Eye Closure Quaternary (TDECQ) analysis

High test throughput

  • High sample acquisition rate up to 200 kS/s per channel
  • Efficient programmatic interface (IEEE-488, Ethernet, or local processor access) enables high test throughput

1Optical Reference Receiver (ORR) is a 4th-order Bessel-Thompson filter, with a frequency response and tolerances as defined by the standards. Tektronix optimizes the response for best nominal fit and highest quality mask test results.
