I have tried RS232 serial communications with pyserial, which worked alright but was not able to communicate quickly and therefore had a low duty cycle of time collecting data vs. NI system SMUs combine power, precision, and speed into a single instrument. Instrument classes. Images – the rear panels of a Keithley 2450 SourceMeter, a B&K Precision Model 8600 DC Electronic Load and a Rohde & Schwarz NGM202 Power Supply. We recently bought the Keithley 2450 to replace our broken 2400 and I am tasked to adjust our measuring station so it works with the new model. Keithley-2450 has a low active ecosystem. Here I use a script running on a Keithley 2450 that communicates with the DMM7510 to get additional readings over TSP-Link. Keithley-2450 has a low active ecosystem. This revision is intended for use with firmware version 1. On the 2450, use the buttons to turn on command logging in event log. The package includes a number of instruments already defined. Under the System column of icons, press Event Log. 0 Keithley 2450, 2460, 2461, 2470 Native LabVIEW 2018 Instrument Driver version 1. Below 20 V the instrument can source or sink up to 1 A, . On a new project i want move on Python language and i do not arrive to drive the K2400 using the Ke24xx. Unfortunately, during the review process, an issue was found with the unit that necessitated a return to a repair centre for repair and recalibration. Source Voltage and Measure Current, Set Measure Units. No License, Build not available. Let me explain I manage to communicate with the keithley2450, and I would like to impose a current for a period of time that I define and measure the resistance and the voltage. by Andrea C » January 20th, 2021, 1:29 pm.
