Compact, full automatic HTOL RF test system for 80 devices under test (DUTs) with up to 2.5 watts per channel and a bandwidth from 20 MHz up to 3000 MHz. The frequency range covers all cellular and connectivity systems up to 3 GHz. The system offers high level accuracies which be archived with automatic level control (ALC) loops in each output. The system has an internal CW signal source with an optional pulse modulator and a graphic user interface (GUI) for an intuitive handling.
up to 2.5 W RF power 19", 43 U 20 ... 3000 MHz
For an automatic monitoring of the transmission parameters (gain of insertion loss) of the DUTs the system offers 80 channels with high dynamic level detectors with high power capability .TSQA-80PM is housed in a 19“ system rack with 43 U. Depending on the position of the temperature cabinet at the customer site, there are variants with RF connectors for RF cables to the DUTs on the right or left site of the system cabinet.
To avoid mutual influences of the DUTs during the tests, TSQA-80PM has high isolation properties between the channels.
The HTOL system offer a LAN interface with a graphic user interface (GUI). Via remote interface test parameters like frequency, output power, limits for insertions losses of the DUTs and test duration can be entered. The software automatically calculates the losses of the cables and presents power levels always with respect to the cable head.
Full Automatic Test Sequence
During the test, the insertion losses of the DUTs is automatically checked for exceeding the limits. The RF power can be taken off individually and automatically from DUTs after failure. This allows the best root cause analysis of the failure. After test time elapses the RF stress is taken off from all DUTs.
