Software in the driver's seat
to a controller that serves as a coordinating device by means of an instrumentation bus. The most widely used buses include GPIB, serial, USB, Ether-net/LAN, PCI, and PXI. There are advantages to each of these formats, and test systems may host instruments having connections for more than one. GPIB...

Split-second measurements spot "hot" drivers
. arm with a 130-gm contact head to a 90 position. A solenoid releases the arm and the contact head impacts the driver face. The critical part is precisely measuring contact time and correlating that to COR. The company turned to ATMD (acam time-measuring device) software and hardware from ), said...
