Features
- Exchangeable Spring Tip
- Modular Probe
- Coaxial REED-Switches
(Switchable Probes) - IC Contacting System for
0.8 to 1.27 mm pitches
PMK‘s standard probes of the PMS, PMT and PMTG series are partly switchable and reach bandwidths of up to 350 MHz in 10:1 mode.
Probes of the PMS series are mainly used for scopes of up to 60 MHz.
The REED switches we use have a breakdown voltage greater than 4000 V.
Another advantage is their long lifetime with over 500,000 switching cycles.
All probes are available with a standard cable length of 1.2 m as well as 2 and 3 meters.
All PMS probes are sent with BNC connectors by default.
