•
Do not use RC filters in conjunction with additional DBK expansion accessories.
•
Prior to installing a resistor to the filter network you must drill a 1/16” hole through
the center pinhole [beneath the board’s silkscreen resistor symbol] as indicated in the
preceding figure. Failure to do so will short-circuit the resistor.
•
Do not drill holes on the board for channels, unless those channels are to receive a
filter network (see preceding statement).
•
Resistors should be ¼ watt, film-type with up to 5% tolerance. Do not use wire-
wound resistor types.
•
A resistor value of 510
Ω
is recommended. Do not exceed 510
Ω
.
•
Capacitors used are to be of the film dielectric type (e.g., polycarbonate or
NPO ceramic), above 0.001 µF.
•
RECOMMENDED: For reduction of both Common Mode Noise and Differential
Mode Noise, use one capacitor between Channel High and AGND; and use a second
capacitor between Channel Low and AGND.
•
For reduction of Differential Noise [when no reduction of Common Mode Noise is
needed] position a capacitor across the respective Channel High and Channel Low.
•
When in Differential Mode, using capacitors between Channel High, Channel Low,
and AGND may cause a slight degradation of wideband Common Mode rejection.
•
When making a RC filter network, always install a wire jumper between the relevant
FILT CAP LO and AGND. FILT CAP LO terminals are located on TB9 and TB10.
