60A Precision Pulsed Source – Performance Series

The SpikeSafe™ 60A Performance Series Current Source is part of the SpikeSafe Performance Series Precision Pulsed Current Source Family. It is capable of supplying output pulses with microsecond rise and fall times – key to precise LIDAR, VCSEL, LED photometric and electrical measurements. This current source supplies precise DC, continuous pulse, and single pulse currents.  A precision hardware-controlled timing system supports pulse widths from 10µs to 15000s. Hardware triggering ensures measurement repeatability. Programmable load tuning alters the SpikeSafe current regulator response to compensate for load conditions, cable impedance, and length. Continuous power conversion technology means no duty cycle or pulse width limitations. Multiple output conductor pairs keep maximum current/conductor below 7.5A, allowing the current output to be routed through standard switching and interconnect devices.

Vektrex also offers a source measure unit for photonic and other applications. Learn more about Vektrex High Current Pulsed SMU.

An optional bias current module supports junction temperature (Tj), thermal resistance (RΘ), and dynamic thermal impedance measurements.

Devices being tested are protected with a gentle turn-on during ramp-up and with SpikeSafe load protection during operation. SpikeSafe load protection continuously monitors voltage and current patterns and instantly shuts down the drive current when device anomalies are detected.

The notable specifications for this current source are as follows: the low range output current accuracy is 0.2%+8mA. The high range output current accuracy is 0.3%+24mA. The pulse width range is 10µs-15000s and the pulse width accuracy is 1.3µs. The pulse rise/fall time is 3µs-5µs and the typical pulse width jitter is 30ns. 

Vektrex-developed Control Panel Software Application is delivered with this current source.

60A Source Pulse Shapes

Precision pulsing is key to best practices measurements. The 60A Precision Pulsed Current Source offers programmable pulse width flexibility. It is capable of long pulse widths (ms to seconds) and short pulse widths (100us pulse widths and faster). Pulse width accuracy is 2.3us with pulse rise and fall times of 3us to 7us. Ramp time is adjustable from 1000V/s, 400A/s to 10V/s, 400mA/s.
