2.1.1 Block diagram Fig. 2-1 shows the MP1763C block diagram. 2.1.2 Data signal MP1763C consists of A08,A10,A09,A23 and E13 for Data signal. A08 PG generates the programmable pattern and pseudo-random pattern(128 bits of data) These 128 bits of data are multiplexed within the A10 MUX(L),A9 MUX(M) and A23 MUX(H) PKG and are then output via E13 DFF+OUT2 hybrid IC.

SECTION 3 describes how to troubleshoot the instrument when abnormalities occur during measurement or performance checks. 3.2 Repair level Repair of MP1763C is required just to replace PKG, UNIT or HIC. Adjustment will be required for some PKGs, UNITs and HICs. 3.3 Location Location of PKGs, UNITs and HICs are shown on page 3-6/3-7.
This paragraph describes how to find a faulty section. 3.7.1 Data signal problem If the MP1763C does not output data signal, check waveform from at [1] to [11] of Fig 3-2. If it shows errors for both PROG and PRBS, check errors at [2],[4] and [6] of Fig 3-2 by using an Error Detector.

Section 3 Troubleshooting 3.8 Typical output waveform This paragraph shows typical output waveform of the MP1763C. 3.8.1 Data output Page 3-12 to 3-21 are Data output waveform with 50( termination. 3.8.2 Clock output Page 3-22 to 3-25 are Clock output waveform with 50( termination.
3.8 Typical output waveform 3.8.7 ZERO Substitution pattern When the ZERO sub. is selected, logical "1" bit is added just after the final bit of PRBS pattern, this pattern is pseudo-PRBS pattern(2 bits; N=7,9,11 or 15). Bits after the longest string of consecutive "0" of the pseudo-PRBS are substituted by"0"pattern.
Section 4 Waveform Check 4.1 DC voltage check Before checking the waveforms, DC voltage of A07 power supply should be checked. Check DC voltage on A07 PCB referring the figure below. Check Point Adjustment Pot Adjustment Voltage +28V R151 +28.04V +15V R152 +15.15V...
