[DSP-10] Table 1 Voltages

Mon, 10 Jun 2002 19:31:42 +0100

Hello Jim,

I put my measured values between brackets behind yours and the DPS-10
here is running fine.
So expect yours will be ok too.

Onderwerp: [DSP-10] Table 1 Voltages

Hello Group,

I am in the "Power Up and Initial Testing" stage of DSP-10 assembly.  My
question is about the Table 1 nominal DC voltages that may be expected
from a properly operating main board.  My first seven voltages match
those published in the October 1999 QST.  My last six voltage
measurements differ substantially from the measurements given in QST.
My measurements are as follow:

R110,  1.8 VDC  (2.0 VDC)
U105 pin 3,  2.3 VDC   (2,5 VDC)
U106 pin 3, 3.6 VDC    (4.0 VDC)
R59,  1.39 VDC		   (1.6 VDC)
U8 pin 3,  1.6 VDC     (2,5 VDC)
U9 pin 3,  3.2 VDC     (3,5 VDC)

All voltages are referenced to ground.
These measurements were taken with the DSP-10 board not connected.

Any comments would be appreciated.

73,

Jim Albers, N9CYL
