Theory of Operation-318/338 Service

PROBE COMPENSATION  <4>
In the probe compensation mode, an external clock is supplied to the ACQ memory as data through A02U244A and
A02U244B gates.  Channel 8 of the acquired data is used as the trigger, and channel 9 is used for data (U228-6,7 <3>).
The MPU recognizes over- or under-compensation from the acquired data of channel 9.  (Channel 9 is the result of the
clock signal compared with Threshold A.)

318 A03 ACQ CONTROL BOARD  <5>  <6>  <7>
The A03 Acquisition Control board (parallel data) has two registers and memory that acquisition parameters are loaded
into before data acquisition.  It also contains other circuitry that controls the trigger sequence and the acquisition memory.
Simplified block diagrams are shown is Figures 4-2 and 4-3.

Figure 4-2 shows a simplified version of all the circuitry on schematics <5> and <6>. Figure 4-3 shows a simplified version
of schematic <7>.
