Summary of TEKTRONIX ADDS INDUSTRY-FIRST TECHNOLOGY WHICH ELIMINATES PULSE TUNING IN NEW ALL-IN-ONE 2601B-PULSE SYSTEM SOURCEMETER
Tektronix announced the 2601B-PULSE System SourceMeter, combining a high-speed PulseMeter pulser with DC SMU functions. It sources 10 μs pulses up to 10 A and 10 V without manual pulse tuning for device impedances up to 3 μH, reducing self-heating errors. It retains all 2601B SMU ranges (40 V, 3 A DC, 10 A pulse), includes dual 1 MS/s 18-bit digitizers for simultaneous current and voltage waveforms, and is supported by KickStart v2.3. It targets VCSEL/LIDAR, LED, semiconductor characterization, fault power, and surge protection testing.
Parts used in the2601B-PULSE System SourceMeter:
- 2601B-PULSE System SourceMeter instrument
- PulseMeter technology (built into 2601B-PULSE)
- Standard Model 2601B SMU ranges (40 V, 3 A DC, 10 A Pulse)
- Dual 1 MS/sec 18-bit digitizers (built into 2601B-PULSE)
- Keithley/Tektronix KickStart Instrument Control Software version 2.3
- VCSELs and LEDs (as test devices; application context)
Tektronix, Inc. today announced the new 2601B-PULSE System SourceMeter® 10μs Pulser/SMU Instrument, integrating a high-speed current pulser with DC source and measurement functions in one instrument. The new system incorporates PulseMeter™ technology for sourcing current pulses as short as 10μsec at 10A and 10V without the need to manually tune the output to match device impedance up to 3μH. This is critical for minimizing device self-heating, which for optical devices, can result in erroneous measurements and the potential for damaging test equipment. The new 2601B-PULSE also includes all current and voltage source measure unit (SMU) ranges that are available in Keithley’s standard Model 2601B System SourceMeter® (40V, 3A DC, 10A Pulse). In addition, Tektronix is also releasing version 2.3 of Keithley’s Instrument Control Software “KickStart” to support the pulsing function of the 2601B-PULSE.
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.
Advancement in Testing with LIDAR in Mind
The 2601B-PULSE System SourceMeter® was developed to serve the needs and 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 beyond. Built-in dual 1 MS/sec,18-bit digitizers enhance the pulser’s measurement function, enabling users to acquire both pulse current and voltage waveforms simultaneously, without the need to use a separate instrument.
