1.1 System Configuration and Block Diagram
Signal flow of the BI-PHASE function (option)
*3
The signal applied to the BI-PHASE input terminal is binarized by the slicer and becomes
a data signal. The signal multiplexer selects the polarity of the pulse width to be
measured—from the rising slope to the falling slope (positive) of the data signal or from
the falling slope to the rising slope (negative)—depending on the measurement function
(measurement item) that you selected.
Signal flow of the level measurement function (option)
*3
The signal applied to the BI-PHASE input terminal or the RF input terminal is input to the
amplitude measurement circuit before the slicer, and the amplitude is measured. The
measured amplitude value is processed by the CPU and displayed as a numeric valu-
on the 7-segment LED
Signal flow of the EXT I/O (option)
*
The condition of the input signal at each pin of the EXT I/O terminal is read by the CPU
and the stored setup information is recalled. In addition, the measurement result is als
output from the EXT I/O terminal
