Write Portion Check
Description
The measurement system verification verifies if the write data generates. The write data is
observed by the oscilloscope. The write data and clock signal are generated by the
E5037C/D, then the signals are mixed by the E5043A/C. This checks the E5037C/D,
E5043A/C, E5029K and the cable connection.
Figure 2-9 shows the test signal flow in the write portion check.
