S3026P
Precision PSMU
S3026P is a standard single-channel pulse current source/measure unit that delivers high-precision current pulses up to ±1.5 A. It is compatible with mainstream PXIe chassis, supports conventional SCPI commands for software development, can be configured as either a master or slave to enable multi-module synchronization, and offers synchronized measurement of pulse current and voltage.
Features
Pulse Width
Minimum 1 μs, maximum 500 μs
Suitable for faster tested devices to better avoid the impact of temperature on test results
High-speed Measurement
ADC up to 100 MSa/s
High Range
Supports pulse current output up to ±1.5A
Measurement ranges: ±0.15A, ±0.75A, and ±1.5A
Stronger Load Adaptability
Test loads with different characteristics to ensure that the waveform does not experience overshoot or other distortions
High Speed Synchronization
Multi-channel and multi-mode collaborative measurement
Real Time Reading of DUT Voltage Drop for Pulse Current
No additional equipment required, precise monitoring of current testing conditions, real-time reading back of test results
Functions and Advantages
Sweep Mode
- Supports single linear, double linear, constant, logarithmic, and list sweeps, with a maximum of 65535 points per sweep.
- It also supports infinite pulse and DC output modes.
- List sweep is flexibly configurable as needed.

[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%.
