Miniature Probes 2.5 mm
PML Low Z-Series
Low Z-Miniature dividers are a low-cost alternative to active probes for
high frequency measurements. They‘re built for use with instruments
having 50 Ω inputs. Due to their low input impedance in the range up to
100 MHz the signal source must be able to accept some loading without
difficulties. Other coaxial connectors e.g. SMA or N on request. The illust-
ration shows a PML Low Z probe with optional SMA connector.
