Acquisition

The acquisition board is mounted on the bottom of the instrument. It has several
custom CMOS ASCIs ,several full custom bipolar ICs, RAM for the acquisition
memory, and other miscellaneous circuitry. The acquisition board takes the data
acquired by the probes, determines when to clock the data into memory, and
communicates the acquisition information with the rest of the instrument.

The acquisition board also contains the LPU circuitry which interfaces between
the VXI bus and the acquisition circuitry.

No manual calibration or adjustments exist. All calibration is done by software
but requires the adjustment/verification fixture (671-3599-XX) to be used for
proper deskew. The calibration procedures are described in the

Adjustment

Procedures
