output signal level has been set to nearly 9 V peak-to-peak (ST7580 TX_GAIN

parameter = 26), corresponding to 127 dBµV rms.

●

FSK: The test pattern consists of the continuous transmission of 200 ms packets with

50% duty cycle, random payload and FSK modulation with 82 kHz frequency at 9600

baud, deviation 1. The output signal level has been set to nearly 6 V peak-to-peak

(ST7580 TX_GAIN parameter = 21), corresponding to 126 dBµV rms.

Conducted emissions test setup

The conducted emissions measurement results are reported below. Quasi-peak

measurements have been performed, as required by the EN50065-1 standard document,

for measurements above 150 kHz. Peak measurements are performed for frequencies

below 150 kHz to also show the output signal level compliance. The measured spectrum is

always compared to the EN50065-1 compliance limit mask.
