• Error 5111 on Keithley 2461

    Hi,<br> <br> We are new to 2461 coming from 2430.&#160; We are encountering 2 issues:<br> <br> 1. We are trying to setup a pulse measurement for a pulse width of 250us at 2% duty cycle at a force current of 2.7A.&#160; However, when we try to generate, it displays Error 5111.&#160; We play around with different timing (such as pw=4ms, offtime=12.5ms, at source current of 1A) and it can generate (see img1).&#160; As per manual, the minimum pulse width is 150us.&#160; Sometimes even if we set at 50% duty cycle at 12.5ms pulse width, were still getting Error 5111.&#160; What is the proper way to setup pulse measurements and get discrete values on the screen (not using Digitize or turning Acquire measurements off)?<br> <br> 2. We are measuring BVdss of a MOSFET and sourcing 250uA (non-pulsed).&#160; We are getting the correct reading of the breakdown voltage.&#160; However, the meter display is not showing the 250uA Source current (see img2).&#160; What is happening here?<br> <br> TIA
