Description
DESCRIPTIONWhen it is required to make a measurement at a node of an RF circuit, connecting to the circuit using a normal oscilloscope probe, even on the x10 setting can change the behaviour of the circuit.
For those difficult cases, you
need a special, high impedance and low capacitance, probe like Im selling here. Also you can notice two , soldered in series, capacitors on the input of probe. It is Hi Q, Low ESR, Hi V (100v according specification). That capacitors help windstand high DC voltage on the input.
This lot includes assembled and well tested RF probe PCB. It suppose to be placed in some tube or enclosure. Even old marker pen will be ok.
Also you need solder 50 Ohm coaxial cable to probe output. For people who are too lazy to do it, they can buy from me https://www.ebay.com/itm/334454149650 a version of the probe with 30cm SMA-SMA cable and an already soldered SMA connector on probe.
To get accurate results it is important that the ground probe contacts an RF ground close to the point on the circuit.
So to solder the wire somewhere on the RF probe ground surface and then connect it to the ground of tested device.
