而自己就以 Borland C++ Builder (BCB) 控制 Anritsu MT8852B-BLE 去量測 Nordic BLE 的 產品!
其中製造端所測試項目為:
Verify of the maximum peak and average RF BLE output
power. The output power test performs power measurements on the DUT transmitted
packets in follow condition.
2. BLE Carrier and Drift Test
The
carrier drift test performs an initial carrier frequency and a frequency drift
measurement
over the length of the packet received.
3. BLE Sensitivity Test
For
BLE sensitivity measurement the MT8852B first sends the BLE Rx Test command to
the EUT and then transmits BLE reference packets with a pseudo random payload
(PRBS 9) to the EUT at a minimum power level. The EUT counts the number of
received packets and sends this value back to the MT8852B. Frame error rate
(FER) calculation is performed by the MT8852B test set. The test is repeated
for each of the frequencies selected (LOW,MEDIUM and HIGH).
4. BLE Modulation Index Test
This test measures the
modulation characteristics on the EUT
output for each of the frequency ranges selected (LOW, MEDIUM and HIGH)
控制流程部分:
測試程式必須先對待測物下其相對應的command使其進入BLE test mode 再控制 BLE 測試儀去對DUT 進行BLE的量測!
