13. Test information
Fig 21. Test set-up for measuring demodulation delay
(1) Square wave TTL signal 300 Hz, duty factor = 50 % for measuring signal bandwidth
(see Figure 3
).
(2) DATA_IN
+ LOW for measuring total harmonic distortion (see Figure 3).
(3) Tuned for f
cr
= 132.5 kHz.
(4) The CISPR16 network provides a −6 dB attenuation.
