Hi, I am Hock Eng from Keysight Technologies
In the IoT device manufacturing facilities,
it is always important to do a final functional check
on the finished good before it is boxed and shipped to the customer.
A small IoT device such as this wearable or a sensor tag
which has a Bluetooth Low Energy (BLE) function in it.
An easy way to do a functional check through the mobile phone BLE pairing.
But sometimes, this kind of mobile phone pairing
is not sufficient enough to detect some manufacturing defects.
So, this is way our Keysight X8711A IoT Device Functional Test Solution
can help to solve this kind of problem.
In this video, we shall do a comparison of a BLE Signaling functional test
between the mobile phone pairing and the X8711A.
This is an example of mobile BLE pairing testing.
On my right side, is a modified DUT.
we changed some components inside the PCBA,
to simulate a missing components or component change mistakenly.
On the left side, is a good DUT.
And as you can see, these two DUT can paired (successfully) to the mobile phone
and both are functioning well.
Then, the RSSI measurement of the two DUT
provide almost the same value.
Now, let's use the Keysight X8711A
test solution to perform the BLE over the air (OTA) signaling test.
This is the modified DUT (bad DUT),
and we shall run the TAP software.
The software shall automatically detect the DUT
and then perform the packet error rate (PER) test and also
the (advertising channel) power measurement.
As you can see the advertising power measurement has failed.
This is because, the modification which we have done on the bad DUT
causes the power level to drop significantly.
While mobile phone pairing test is an easy way to do the functional test
but it is not sufficient enough to filter out
the defects in the bad DUT as shown in the demo.
This could lead to shipping out faulty finished goods (to customer)
and overall may increased your (business) cost.
One of the reason why mobile phone pairing is not sufficient enough is because,
typically it only provides the RSSI measurement.
Whereas, our X8711A solution provides 3 parameters.
Besides the RSSI, we also perform the packet error rate testing (PER)
and also the transmitted (advertising) power measurement.
This is why the Keysight solution is a better way to detect the manufacturing defects
in the IoT device manufacturing facilities.
Thank you for watching this video.
