Hi.

My custom board and CC2530EM Smith Chart show differently on the network analyzer.

PC tool is continuous rx mode of SmartRF studio7.

When start button is pressed, CC2530EM is moved nearby 50 ohm selected frequency(2445MHz).

But custom board is not.

CC2530EM is on the SmartRF EB5.

Custom board is CC2530 + CC2590.
