Ultra Wideband Testing on the UltraFLEX.
More and more RFID and Location “Tag” devices are adopting the Ultra Wideband Pulse Position Modulation techniques outlined in the ieee spec 802.15.4. These UWB-PPM radios are becoming popular in the consumer space and require cost-effective, high-volume production test solutions.
UWB-PPM radios operate in the 6-10.5Ghz range and have modulation bandwidths approaching 2 GHz. UWB-PPM radios typically have four (4) RF ports: one (1) TX port and 3 (3) RX ports. TX output power can be as high as +20dbm.
Typical TX tests include:
- TX Output Power
- TX Spectral Mask
- TX Pulse Accuracy
- TX Pulse Jitter and NMSE
RX test include:
- RX gain,
- RX PER
- Time of Flight,
- Angle of Arrival
The Ultra Flex UWB option, UltraWaveLX-UWB is designed for high volume RF testing of UWB-PPM radios. Fully compliant RF test are done at production speeds.
One UltraWaveLX-UWB instrument set gives the User 16 bidirectional 6-18GHz ports capable of 802.15.4 complaint testing. Each port has a time delay feature that is used to support Time of Flight and Angle of Arrival type tests.
This paper describes the UltraWaveLX-UWB instrument and UWB test techniques on the UltraFLEX.
