Open Circuit Locator
A994
-
The A994 is an open circuit locator for electric and telephone cables wind on the reel; it gives the position of the fault from the inside or outside end of the cable, in percentage to the total cable length. The instrument measures the ratio of the capacitances of the two sections of failed conductor using two high precision i/v converters. The advantage of this method is due to the fact that the measurement error depends almost exclusively on the dimensional inhomogeneity of the cable. The A994 has the unique feature to permit the location of fault in cables with all broken wires. This instrument locates breaks in cables with a total capacity between 2 nF and 5 uF. The distance to fault is displayed on a large LCD display.

PXI 5A Fault Insertion Switch 10-Channel
40-196-001
Fault Insertion Unit
The 40-196 is a 10 Channel 5A Fault Insertion Switch, primarily designed for the simulation of fault conditions in automotive & avionics applications involving the reliability testing of safety critical controllers. It is designed to be able to insert different fault conditions between the test fixture and the equipment under test: Open-Circuit, Short-Circuit between signal pairs, Short-Circuit between signal pairs and user applied fault conditions e.g. Power or GND. Shorting relays on each channel enable UUT signals to be subjected to external user applied fault conditions or to be shorted to the adjacent signal in the same channel. Relays in line with the signal allow open circuit conditions to be simulated on either side or both sides of a channel signal pair. The switching topology of the 40-196 allows channels to be interconnected so that complex fault insertion systems can be constructed.
