Telemetry, telecommand and radio-frequency sections of an automatic test equipment

Both interface sections of one automatic test equipment — telemetry and telecommand, command and control of the radio-frequency chain — in integrated chassis, operated through an on-board web server. Subcomponent responsibility and support to AIT, as a subcontractor to a third-party integrator.

Drawer front panel: interface towards the items under test, command and board-fault indicators, per-channel current measurement sockets and the plug-in card bay
Rear panel: telecommand and telemetry bus on the left, power bus and outputs in the centre, network socket and mains inlet on the right
Command and control board of the radio-frequency section, with the line connectors aligned along both long edges
Operator interface served by the on-board web server: status readout, connection matrix and recall of the preset configurations

The TM/TC section — telemetry and telecommand: the stream that observes the unit under test and the one that commands it — inside an automatic test equipment, built as an integrated chassis operated through an on-board web server.

The second subsystem configures the radio-frequency paths of the same bench, collects their status and reports it to the operator through the same interface. Read together, the two sections document a level of trust rather than an isolated supply: IN SY TO was entrusted with both interfaces of the bench.

The contractual position is itself informative: IN SY TO answers for one subsystem inside a bench owned by a third-party integrator, with its own design, electronics and software scope, and with specialist support during system testing. It is how a small team gets into large programmes.
