Keithley 2010 Service Manual

Table 4-12 through Table 4-16 can be used to trace the analog signal through the A/D multi-
plexer (U163) to the final amplifier stage. These tables show the MUX lines (S3, S4, S6, S7) that
are selected for measurement during the SIGNAL phase of the multiplexing cycle. Also included
are switching states of analog switches (U176) that set up the gain for the final amplifier stage
(U177).
