TLF3000 802.15.4 RF PHY Tester

TLF3000 Bluteooth Production / PHY Tester

TLF3000 RF PHY tester is a wideband, ultra-high dynamic range 2.4 GHz software-defined receiver, signal analyzer and signal generator. It captures and analyses the entire 2402-2480 MHz band simultaneously providing RF PHY testing, signal generation, signal analysis in one powerful package.

The TLF3000 is a highly portable and flexible test platform that due to unique parallel architecture can execute testing much faster than traditional RF test systems.

The TLF3000 802.15.4 Tester is available in two configurations for Developer and Production line test environments.

Developer Configuration

The Bluetooth 802.15.4 developer configuration is specifically designed for use in a development lab environment for regression and pre-compliance testing.

Signal generator mode permits manual control over all the signal sources used for receiver testing. Any combination of the following signals can be generated simultaneously:

 

  1. Packetized 802.15.4 O-QPSK signal with programmable contents
  2. Continuously modulated or packetized O-QPSK signal
  3. Up to 3 independent in-band CW signals, which may be pulsed
  4. In-band AWGN source, which may be pulsed
  5. Out-of-band CW signal

All signal sources are fully parameterized

Signal analyzer mode monitors all 16 channels simultaneously. Any detected packets are captured and analyzed in accordance with the 802.15.4 specification. Tests include EVM, power spectral density, carrier offset and drift, output power as well as symbol timing accuracy. The signal analyzer can process either conducted signals or monitor off-air traffic from live links. The signal analyzer mode also permits the capture of raw IQ data, FM demodulated data, constellations plots or power profiles.

Packet Sniffer mode monitors all 16 channels simultaneously. Any packets which are detected are demodulated and the bit stream either piped directly into Wireshark for live protocol analysis, and/or saved to file. Capture can be restricted to certain RF channels or an RSSI threshold can be set. During capture, a spectrum display is available so that the prevailing RF environment can be monitored.

Production Configuration

The Production license provides a limited GUI with the ability to create script files in a format which can be executed by native language programs or in combination with the Python and C++ dlls. The Production license is specifically designed for use in the Production line environment and is not suitable for hands-on lab use. Signal Generator and Signal Analyzer functionality is not accessible via GUI with the Production license.

Features and Benefits
  • Fast - 2 second boot time, and the in-band emissions test completes in 2.5 ms
  • Fully configurable test coverage and test time
  • Performs RF-PHY testing on live links
  • Simple and intuitive GUI quickly identifies faults
  • Single signal path eliminates the need for multiple pieces of gear
  • Standalone mode - test scripts can reside on a USB stick
