  • The 2601B-PULSE System Source Meter helps avoid any measurement errors 
  • Ideal for testing VCSELs to faulty power management

Tektronix has announced the new 2601B-PULSE System SourceMeter® 10μs Pulser/SMU Instrument that integrates a high-speed current pulser with DC source and measurement functionalities in a single instrument. The new system incorporates PulseMeter™ technology for sourcing current pulses from 10μsec to 500μsec at 10A and 10V without manually tuning the output to match device impedance up to 3μH. This ensures that the current pulse has no overshoot or ringing, thus reducing device self-heating, which can result in erroneous measurements and potential damage to the test equipment. This results in fast rise time, accurate pulse output and high fidelity.

Built for fast measurements

The 2601B-PULSE System SourceMeter®  simplifies the complications of testing vertical-cavity surface-emitting lasers (VCSELs), which are mission-critical for automotive light detection and ranging (LIDAR) applications. The instrument is ideal for testing VCSELs and LEDs, semiconductor device characterization, fault power management testing, surge protection testing and more. Built-in dual 1 MS/sec,18-bit digitizers enhance the device’s measurement functionality, enabling users to acquire both pulse current and voltage waveforms simultaneously, without the need to use a separate instrument.

Automatic pulse output tuning

The new 2601B-PULSE  (40V, 3A DC, 10A Pulse) also includes all current and voltage source measure unit (SMU) ranges. Additionally, Tektronix is also releasing version 2.3 of Keithley’s Instrument Control Software “KickStart” to support the pulsing function of the 2601B-PULSE. The PulseMeter™ technology eliminates manual pulse output tuning irrespective of the amplitude and pulse width to ensure pulse fidelity. For automated system applications, the 2601B-PULSE’s Test Script Processor (TSP®) technology runs complete test programs from inside the instrument for industry-best throughput.

“The 2601B-PULSE System SourceMeter® affirms Tektronix’s commitment to the advancement of technology through leading test and measurement solutions,” says Chris Bohn, vice president and general manager at Keithley/Tektronix. “This new instrument will bring better testing capabilities for engineers, including those who rely on industry-first technology to take innovative strides in automotive applications, connected vehicles and autonomous driving.”

The model is now available worldwide with a one-year warranty.
