EMC near-field probe, spectrum analyzer unmanned aerial vehicle tinysa SA accessories measurement test

Shipping list:

1Pcs 28mmH field circular probe

1Pcs 4.5mm H-field circular probe

1pcs Electric field probe

PCB near-field probe, designed using 4-layer FR-4 PCB,

The ribbon line is wired in the inner layer of the first layer, while the other inner layers are filled with copper.

Compared with the near-field probe with a 2-layer PCB design,

It can effectively reduce unnecessary coupling and accurately locate EMI interference sources.

Usually, we use larger ones to detect the approximate location of the source of interference.

Then use a smaller probe to narrow the search range.

Gradually identify the source of the interference magnetic field in the electronic module.

Using these low-cost near-field probes combined with tinySA ULTRA,

It can achieve more efficient, accurate and flexible EMI rectification than ever before,

thus improving productivity!

Usually, when these probes are connected to tinySAULTRA,

tinySAULTRA's built-in LNA can be used to provide sufficient sensitivity, no external LNA.

If you really need an external LNA for weak signal detection, be sure to turn off the built-in LNA to avoid LNA overload.
