Instrument Drivers

SCPI Makes Life Easy

 

How many times have you looked for an instrument driver, and find that it doesn’t exist? It happens, and that overwhelming feeling of doom looms overhead. Don’t let that feeling overcome you until you have verified that there is not a SCPI interface. SCPI stands for “Standard Commands for Programmable Instruments.” As the name says there could possibly be a set of standard commands that will help you still be able to control your instrument. Most instruments support SCPI as their protocol, which is lucky for us developers.

Taking Control of Instruments With LabVIEW

If you have ever thought "Man, I am so sick of pushing these buttons on this instrument I could punch someone!", or your instrument is strategically placed on the opposite side of the lab from your computer, then you are in luck. The everyday mundane tasks of using instrumentation for your projects is inevitable. Sometimes it requires pushing buttons every hour or so, and sometimes it requires pushing those buttons 30+ times a minute. In short, doing this for days on end can lead to mental breakdown. Science proves it.

The Secret Combination to Unlocking AutomationDirect Stepper Motors in LabVIEW

I was working on a radiation leakage test system trying to control a STP-DRV-4850 motor designed to spin an array of D-tect sensors around a unit under test.  I was able to spin the motor using AutomationDirect's utility program, SureStep Pro and everything was looking good, until I tried to send the motor controller serial commands from LabVIEW.
