and then press MARKER
(PEAK SEARCH) and re-adjust LC DIP to offset the signal peak
approximately -17
kHz
(to the left). This is done to compensate
for operating the
A4A4
Bandwidth Filter on extender boards. If
unable to achieve a “dip” in signal amplitude, increase or decrease
value of
A4A4R16.
Refer to
