• Set the W3 jumper to TRIG/CLK PORT A(B), shown
in FigureC-5b, to select the CLK10 source as the
TRIG/CLKPORT A(B) on the VXI-8360T front panel. When
selecting the trigger card as the CLK10 input source be sure
to set jumper W7 to set the direction of CLK10 through the
TRIG/CLKPORT A(B).

W4—CLK10 Source Select
In Slot 0 operation the CLK10 Source Select jumper allows you to select
the source for the VXIbus CLK10 that is routed to the backplane.
The default setting, Internal Oscillator, shown in FigureC-6a, uses the
internal 10MHz ±100 ppm oscillator as the VXIbus CLK10 source.
Set the W4 jumper to External Source, shown in Figure C-6b, to use the
front panel SMB or the TRIG/CLK PORT A(B) as the CLK10 source.
Jumper W3 External CLK10 Source Select is used in conjunction with W4
when W4 is set to select an external oscillator as the VXIbus CLK10
source.
