[DSP-10] U107 Voltages

[Yamamoto Jiro]

Hello,

I am now doing an initial testing for my DSP-10 with kDSP-10 module. At 
the point of D2-A1 and D1-A1's values I got 0.0V and 0.48V 
respectively. So I decided to go to "Serial Bus Diagnostics" page by 
Bob to see if the U107 shift register is working properly. By using 
with the udiag1.exe, I confirmed that all the four lines are correct. 
And I proceed with running UHFA.EXE to get my own U107 Voltage table 
for each RF gain. Here is the voltages measured;

RF Gain QA QB QC QD QE QF QG QH
  100   0  0  0  0  5  0  0  0 Volts 
  94    0  0  0  04.9  0  04.7
  88    0  0  0  0  5  0  5  0
  82    0  0  0  0  5  5  0  0
  76    0  0  04.7  0  5  0  0
  70    0  0  5  0  0  5  0  0
  64    0  5  0  0  0  5  0  0

and the normal voltages from the web page are;

RF Gain QA QB QC QD QE QF QG QH
  100   0  0  0  5  0  0  0  5 Volts 
  94    0  0  0  5  0  0  5  0
  88    0  0  0  5  0  5  0  0
  82    0  0  0  5  5  0  0  0
  76    0  0  5  0  5  0  0  0
  70    0  5  0  0  5  0  0  0
  64    5  0  0  0  5  0  0  0

Interestingly the pattern in each table seems to be same excerpt for my 
values being "shifted" to the right in one column??? I don't know how I 
can explain this... Any help will be appreciated.
