Patent ID: 11870595
Assignee: ROHDE & SCHWARZ GMBH & CO. KG
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A test device for performing packet error rate (PER) measurement on a Bluetooth Low Energy (BLE) channel, the test device comprising:
a transceiver for establishing an isochronous BLE connection between the test device and an implementation under test (IUT); and
an analyzer coupled to the transceiver to control the transceiver and exchange digital data with the transceiver for measuring a PER on the established isochronous BLE connection between the test device and the IUT,
wherein the transceiver is configured to send test data packets from the test device to the IUT, receive response data packets from the IUT generated according to digital data received from the analyzer, wherein a separate response data packet is sent from the IUT for each test data packet received by the IUT,
wherein the test data packets and the response data packets are transmitted in time slots of a predetermined time grid, and there is one or more empty data packets between a transmission of the a test data packet and a corresponding response data packet, and
wherein the analyzer is configured to calculate, based on the digital data exchanged with the transceiver, the PER based on a number of test data packets sent by the test device and a number of response data packet received by the test device.
