73A-270 Arbitrary Pulse/Pattern Generator Module
a. Program TTL OUT B to generate a continuous pulse pattern having a 10
ms active high level pulse with an active breakpoint followed by a 10 ms
active low level pulse with an active breakpoint with the following steps:
IBWRT "1S3R0A0M1003L1006L0C"
IBWRT "0B"
b. Check that TTL OUT B is held at a TTL high level, which demonstrates
that the pattern stopped at the active high pulse breakpoint.
c. Restart the pulse-pattern several times and check each time that the TTL
OUT B signal level alternates between a TTL low level and a TTL high
level as the breakpoints are being recognized.
IBWRT "0B"
IBWRT "0B"
IBWRT "Q"
(Verify that the pulse-pattern stopped)
