User settable up to 210V

Pulse Width

User settable 200µs minimum with 10µs resolution.

Wideband Noise (Voltage source) SMU4001

<2mV (RMS, 10Hz – 20MHz)

typical into a resistive load.

SMU4201

<21V: <2mV (RMS, 10Hz – 20MHz)

21V to 210V: <3.5mV (RMS, 10Hz – 20MHz)

typical into a resistive load.

OUTPUT POWER, VOLTAGE AND CURRENT CAPABILITY

PowerFlex

PowerFlex technology enables the instrument to achieve full instrument output power across the majority of the voltage range. 3A current limit, limits power at

absolute voltages < |8.33V|. Absolute voltages above |21V| are only achievable on the SMU4201. Output current limited to 0.5A at absolute voltages > |21V|.
