**Load:** 

- R around 100 ohm.
- Operates with pulsed square wave power supply.
- Has linear **average** I-V response with pulsed voltage up to 10KHz. 
- Absolute max voltage is 60V.
- Operates with transient current V/R < 600mA
- Absolute max **average** current is V * duty% / R < 100mA.
- Absolute max power **average** 0.75W.


**Requirement:**
- Voltage range: 0-60 V.
- Frequency range: 0.5 - 4 kHz.
- Duty cycle range: 5%-95%.
- Can accept trigger (4 kHz).
- Can divide trigger (f/2, f/4, etc...).
- Adjustable trigger delay.
- Clean waveform.

I'm not aware of any equipment that fits all those requirement. Most function generator can only reach +/- 10 V. Most bench power supply only supply DC in CV/CC mode.

Analogue/Digital I/O devices (Arduino, DAC, etc.) with faster clock can achieve all those except for the voltage requirement. Perhaps there are some sort of amplifier that can bring the voltage to 60 V? but DC-DC boost modules only works with DC input/output.

Solderless solution would be preferable.

Thanks in advance!
