This PCB test probe from HHF allows easy and quick broadband measurements on microwave circuits up to 4 GHz and higher. This hand-probe is a cheap alternative for high impedance probes for time-domain measurements. Also spectrum analyzer and network analyzer measurements will be supported. This probe allows the measurements of one component of a multi-stage or multi-component design in 50 ohm-environment. The very robust design of the ProMic-probe guarantees a long working life. Thin as well as wide microstrip lines can be easily measured. This model NA-PR1 supports SG-contacts.
