OCP First Page
What is an OCP?
The LM Subsystems and Integrated systems were tested as the vehicle was being assembled in work stands in plant 5. The LM sampled measurements, (ie, 5x per sec., 100x per sec. . . . etc.) were transmitted in a Pulse Coded Modulation (PCM) mode, were down linked , were coupled with plugs in "carry on" measurements, were signal conditioned and then sent to the ACE (Acceptance Checkout Equipment) station. The ACE station displayed hundreds of measurements per second to test engineers manning positions in the ACE room. These measurements were "real time" displayed on "paged" CRT's, bush recorders, and event lights.
The LM was basically tested in a pseudo flight configuration mode. The persons in the LM cabin (LMP and CDR) performed actions under the direction of the "Test Conductor". Personnel in the ACE room then verified the correctness of the resulting measurements coming down from the LM. Each second, hundreds of measurements would be sampled from the LM subsystems.
OCP's were written in a script like manner, with the Test Conductor (TC) reading to the appropriate support personnel.
