PEM CWT AC Current Probes (Rogowski Coils) – Equivalents
PEM CWT AC Current Probes are drop-in replacement for several oscilloscope manufacturers branded current probes.
PEM parts marked with an * are not identical replacements but are instead equivalents with improved upper frequency cutoff (50MHz vs. 30MHz, or 35MHz vs. 23Mhz). In addition, the coils have a smaller cross section (3.5mm vs. 4.5mm) but also lower voltage isolation (2kV vs. 5kV) and shorter coil to integrator cable length (1 meter).
