s00, s01, s02... s07
N2268A
50Ω 3.5 GHz Dual 4-to-1 MUX Module
s00, s01, s02, s03; s10, s11, s12, s13
a. A channel number on a matrix module is formed in Slot-Row-Column format, i.e., channel address s23 means row 2,
column 3 in Slot s.
b. The N2260A and N2266A can be used as an 80-channel 1-wire MUX module, a 40-channel 2-wire MUX module, two
20-channel 2-wire MUX modules, or a 20-channel 4-wire MUX module.
c. The Low (L) terminals of the 40 2-wire channels form the first 40 1-wire channels (Channels 00-39), and the High (H)
terminals of the 40 2-wire channels form the second 40 1-wire channels (Channels 40-79).
d. The first channels (CH00 & CH20) of either banks (BANK 0 and BANK 1) form Channel 00, the second channels
(CH01 & CH21) of either banks form Channel 01, and so on.
