3701 Line Probe
Its principal application as per FCC/OST MP-4 and ANSI C63.4-1981 is for those situations where the line current is too great for the use of a LISN. The Model 3701 Line Probe also meets the requirements of MIL-STD 461.
For operation, the probe is attached to the bare conductor carrying power to the equipment under test. A female BNC coaxial connector is located at the base of the probe for connecting the probe to the test equipment. For multiple phase equipment, the probe can be quickly detached from one line and attached to another. The unit is constructed of brass, delrin and line phenolic.
ETS-Lindgren warrants its LISNS and PLISNS to be free from defects in material or workmanship for two years. Annual recalibration is suggested.
