Reference Selection
CerePlex Exilis has a versatile reference selection feature that offers customers
great freedom on selecting the proper reference for their setup and achieving
optimal noise performance. There are two reference wires connected to the
Omnetics connector of each bank. These two wires are shorted on the device to
form a single reference, labeled as A, B, C (in
). There are three SPDT
switches (SA, SB, SC), one for each bank, to allow each bank to select its
reference from its Omnetics reference wire or a common reference R. There is
another 4-in-1 SPST switch (SR), which allows the user to connect the common
reference R to one of the following 4 references: A, B, C, and G (Ground). The
common reference R is connected to an exposed solder pads on the bottom of
the device. If needed, the user can solder a custom reference wire to the solder
pad with none of 4 references are selected in SR and use it as a custom
reference. The reference selection schematic and matrix are detailed in
