Recently, the test institute of the test institute has completed the new PTI-I telemeter PCM tester and successfully passed the expert acceptance review. The newly developed tester is easy to operate, full-featured, lightweight, and portable, which breaks the long-term dependence of imported foreign products and plays an important role in the implementation of the yard's “Confirmation of Test System Technology Status” and the technical personnel's R&D system.

The new telemetering PCM tester can generate PCM signals with different properties and can realize the reliability test of remote real-time ground-based systems such as RDAS. The project is a self-designed research project for the test institute of the test flight. After four years of intensive research by the project team, and through a large number of experiments and field tests, the entire prototype development and nearly ten thousand words of user guides were completed in October 2010.

The tester has many technological innovations. It broke the long-term outsourcing dependency of the test house. Through self-study, it has promoted the deep understanding of telemetry ground real-time systems by test and scientific research personnel and provided technical reserves for the normal operation of flight real-time monitoring systems. The performance of the tester including signal severity, ease of operation, and intuitiveness of the test is more practical than that of the purchased product. The instrument uses common devices and assembly language, starting with basic circuit and micro-function driver design, making the entire design idea not Restricted by any product, it has original innovation meaning. The self-checking fault-tolerant design of the white box makes the tester's actual operation fault-tolerant, high reliability, and good man-machine interaction. At the same time, the designers for the first time have a theoretical summary of the synchronic elements that affect telemetry ground real-time systems, and have important engineering and academic reference values.
