Fig.16 Test set-up for measuring THD and bandwidth of the TXOUT signal.

(1) Square wave TTL signal 300 Hz, duty factor = 50% for measuring signal bandwidth (see spectrum Fig.3).

(2) DATAIN= LOW for measuring total harmonic distortion (see spectrum Fig.3).

(3) Tuned for fcr = 132.5 kHz.

(4) The CISPR16 network provides a −6 dB attenuation.
