7.2.1

Conducted emission (CE) measurements

The EN50065-1 standard describes the test setup and procedures for these kinds of tests.

The compliance tests have been performed with 230 V AC isolated supply. The test pattern

consists of a continuous transmission of the two S-FSK tones, alternating at 2400 baud.

The output signal level has been set to 2.5 V rms (ST7570 TX_GAIN parameter = 23),

corresponding to 122 dBµV rms measured at the standard two-line V-network (also called

line impedance stabilization network, or LISN) measurement port.
