[1] Test Conditions: Pulse width is set to the maximum pulse width (500 μs). Current is measured using a high-precision ammeter with a measurement speed of 0.02 NPLC.

[2] Internal switching; no user configuration required.

[3] With a 10 Ω resistive load, voltage noise across the load is measured, and current noise is calculated via I = V / R.

[4] Bias current > 1 mA. Pulse width is measured from 10% of rising edge to 90% of falling edge.

[5] 0.5 Ω resistive load.

[6] Total inductance of output leads and DUT < 200 nH (at 100 kHz).

[7] Iset:Set current; Ibias：Bias current; D: Duty cycle;Vlimit Source voltage setting, adjustable range 5 V to 40 V;Vload: Maximum load voltage drop.

Note: In current mode, the unit automatically monitors the loop condition. If an external open circuit is detected, the unit disables output and reports an error.

Example: Using a 1 Ω resistive load, with the sweep current range from 0 A to 1.5 A, the Vload is 1.5 V. With Ibias set to 0 A, D < 3 / [(Vlimit - 1.5 V) × (1.5 A - 0)].

When Vlimit is set to 20 V: D < 10.8%.

When Vlimit is set to 10 V: D < 23.5%.
