Bias option supports thermal measurements
An optional bias current module supports junction temperature (Tj), thermal resistance (RΘ), and dynamic thermal impedance measurements.
Switch option supports low-level parametric measurements
An optional A/B switch allows load wiring to be automatically routed to an external parametric measurement unit such as a femtoamp source/measure device. This option supports low-level measurements such as reverse leakage measurments.
Devices being tested are protected 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 0.04%+700µA. The high range output current accuracy is 0.08%+4mA. The pulse width range is 1µs-15000s and the pulse width accuracy is 1.3µs. The pulse rise/fall time is 350ns-4.5ns and the typical pulse width jitter is 30ns.

20A Source Pulse Shapes
Precision pulsing is key to best practices measurements. The 20A Source Measure Unit offers programmable pulse width flexibility. It is capable of long pulse widths (ms to seconds) and short pulse widths (100us pulse widths and faster). With the pulse source, minimum 10us pulse widths are available with upgrades for fast precision pulsing (1us pulse widths). Pulse width accuracy is 1.3us with nanosecond pulse rise and fall times. Ramp time is adjustable. Fast transient response saves devices.
This model includes is available for use with an internal power supply (300W or 600W). For total output power, 3.2kW per source channel, an auxiliary power supply is required. Please consult Vektrex for auxiliary power supply recommendations.
