Test F-1: Front Panel Outputs

Description

This test checks the output levels from the front panel Trig Out and Clk Out ports.
There are four parts to the test, as follows. See Figure 2-6 for a summary of the
trigger sources and paths for parts A, B, and C.
Part Title
A INTernal Trigger
Source Test
B TTL/ECL Trigger Line
Source Test
C Trig In Port Source Test
D 10 MHz Clk Out Signal
Test

Description
For this test, the Trig Out port level should start at +5V, then go to 0V for two seconds,
and then go back to +5V.
Checks the Trig Out port output using each TTLTrg and ECLTrg trigger line as a trigger
source. For each TTLTrg/ECLTrg trigger line, the Trig Out port level should start at +5V,
then go to 0V for two seconds, then go back to +5V.
Checks the Trig In and Trig Out ports on the command module, using the seven TTLTrg
and two ECLTrg lines (in turn) to check input/output. For each TTLTrg/ECLTrg Trigger
Line, the Trig Out Port level should start at +5V.
When a TTL signal is applied to the Trig In port, the Trig Out port level should go to 0V
and stay at 0V until the signal is removed from the Trig In port. Then, the Trig Out Port
level should return +5V.
Checks the output from the Clk Out port on the command module front panel.
The oscilloscope display should be a 5V pp square wave at 10 MHz (period = 0.1
sec).
