Theory of Operation
2.5 Test Clips
The standard Test Clips have no active components, but the ribbon cable is temiinated at both
ends with a series 300 ohm resistor for impedance matching. There are 10 Kohm puUup resistors
in the Interface Buffer which are applied to the DUT through the 600 ohms of the Test Clip.
The High Impedence Test Clip has an active buffer at the clip head which presents 500 Kohm
impedence to the DUT. The clip head is powered from the VCC pin of the DUT.
