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.

Near Field Probes 30 MHz up to 6 GHz
XF1 set
The XF1 set of near field probes consists of 4 passive near field probes and one passive E field probe for making measurements in the development phase of the magnetic and electric fields in ranges from 30 MHz to 6 GHz. Due to their integrated impendance matching, the probes are less sensitive in the lower frequency range than the RF type probes. The probe heads of the XF1 set allow for the step by step identification of interference sources of the magnetic field on an electronic assembly. At first, for example the XF-R 400-1 detects the fields which the assembly emits in total. Next, using higher resolution probes the interference sources can be more precisely detected. The E field probe is used for the detection of electric interfering fields near the assemblies. With trained use of the near field probes, field orientation and field distribution can be detected. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They have an internal terminating resistance.
