No Tuning of Output Required up to 3 H. Saves Time and Money

When outputting current pulses, cabling and inductance can be a problem. Inductance can have a limiting effect and could even be damaging. Quite often, the inductance can be different from device to device, even when testing laser diodes on a wafer. The effect of inductance on a current source is that inductance resists changes in current. This can cause the current source to increase the output voltage. The result is overshoot and ringing as the pulse settles. This may not be acceptable in your test. Some solutions require tuning to compensate for these behaviors, which can be time consuming. The 2601B-PULSE’s control loop system eliminates the need to tune for load changes up to 3 µH so that your pulse has no overshoot and ringing when outputting pulses from 10 µs up to 500 µs at a current up to 10 amps. This ensures a fast rise time, so your devices are sourced with a current pulse to properly characterize the device or circuit. The images to the right show the performance of a competitive modular SMU outputting a 5 A, 50 µs pulse on a device with an impedance of 3 µH compared to the 2601B-PULSE with PulseMeter technology.

Typical pulse output from a competitive SMU with overshoot and 6.47 s rise time.
2601B-PULSE output without overshoot and 1.4 µs rise time.

Achieving Fast Pulse Measurements for Today’s High-Power Devices
Green initiatives and energy efficiency standards worldwide have motivated engineers to find ways to design more efficient semiconductor devices and integrated circuits, and measuring the true state of these devices without
the effects of self-heating is critical. Pulsed characterization is a solution to this issue. The use of a pulsed stimulus demands faster measurements. For high-speed digitization or waveform capture applications that require these capabilities, Keithley’s High Power SourceMeter® Instrument also includes two high-speed ADCs for measuring current and voltage simultaneously. These ADCs use sampling technology like an oscilloscope and take snapshots of the signal over time. Each high-speed ADC samples at a rate of up to 1 MHz with 18-bit resolution, which is much higher than the typical 8-bit resolution of an
oscilloscope, resulting in more precise transient characterization in comparable bandwidths. Coupled with the ability to measure asynchronously from the source, this feature makes the 2651A and 2657A ideal for many waveform capture and
transient characterization applications.

Lean Factories Are Critical to Manufacturers’ Success
Today, manufacturers need to speed products to market, reduce costs, and keep customers happy. That means manufacturers must build lean factories that create seamless flows of people, material and information, and prevent the build-up of inventory and excess equipment.
The Challenge
Yet as demand grows, manufacturers need to increase test capacity for products,

TRIPLE THE DENSITY OF A TEST RACK
The Model 2606B form factor (only 1U high) is a perfect fit and improves density by 3×, because there is no need for an additional 1U thermal spacer between units (for air flow).
Most bench source measure units on the market today are 2U high

which requires placing additional racks of test equipment on the plant floor.
