In addition to the probes included in the PS-400 probe set, the PS-500 near field probe set includes a probe with a fine metal tip that allows contact with the circuit being probed to measure levels directly on the trace.
The H-Field Loop probe allows detection of magnetic noise emanating from chassis seams, ribbon cables and connector pins.
Using the probes the test enigineer can quickly find and suppress the EMI at the source, before resorting to other means of EMI suppression.
The probe set can be used with the optional Com-Power PAP-501 RF Preamplifier with 20 dB nominal gain from 10 MHz - 1000 MHz. The preamplifier improves sensitivity of the spectrum analyzer to low amplitude signals picked up by the near field probes.
