Checking Proper Connection of SMP Connectors
After you have replaced the AWG10G board or OUT10G board(s), be sure to verify
that the center contacts of the SMP cable connectors do not short the ground
terminals at J100, J110, J150, and J170 on the OUT10G board(s).
You need a digital multimeter to check the proper connection.
Perform the following steps:
1. Set the digital multimeter to the
Ω
mode.
2. Attach the red test lead to the transmission line near J100 on the OUT10G
board. See Figure 4-17.
3. Attach the black test lead to the connector housing at J100 on the OUT10G
board. See Figure 4-17.
4. Check that the digital multimeter reading falls within the range of 30
Ω
to
70
Ω
.
5. Repeat steps 2 through 4 for J110, J150, and J170.
6. If your instrument has two OUT10G boards, repeat steps 2 through 5 for the
other board.
