Hi, I am Hock Eng from Keysight Technologies.
In the previous videos, we have shown how easy it was to perform a
Bluetooth Low Energy (BLE) Over-The-Air Signaling test
using the X8711A IoT Device Functional Test Solution.
The X8711A test solution runs on the Keysight Test Automation Platform (TAP) software.
Sometimes, you may find that the test time running on the BLE signaling test is too long,
especially if you are in the manufacturing environment facilities.
In this video, I am going to show you how to optimize or
reduce the test time when performing the BLE signaling test.
Let's jump right into the TAP software.
Open the BLE standard signaling test plan (file).
Now, there are two scenarios which I am going to cover in this video.
The first part, we are going to assume that we do not know the
BLE device under test (DUT) BLE specifications and characteristics.
For example whether it supports the Active Scan or Connect Request mode.
Or what is the Advertising interval duration of the BLE DUT?
Hence, we shall perform a full system (scan) discovery test.
First, go to the BLE Device Discovery (step 1).
On the right side (Steps Settings), enter the max 10s for Active Scan Time
and 4s for Connect Request Scan Time (under the "Advanced Settings").
Then, go to (step 2.1.1.1) Measure Advertising Interval and on the right,
under the "Basic Settings", change the Selection to Maximum.
Then, RUN the test plan.
Now what this does is that the software shall detect the MAC address of the DUT.
Then, it will detect whether the DUT supports either the Active Scan or Connect Request operation mode.
And lastly, it will measure the advertising interval duration of the DUT.
Hence, a typical test time for full discovery mode is about 1 minute.
OK. You have done a full discovery mode
or perhaps you understand vey well the behavior of your BLE DUT.
You can greatly reduced the test time by performing these steps.
First, under the BLE Device Discovery (Step 1),
fix the MAC address of the BLE DUT.
Then, enable either the Active Scan or Connect Request mode (User Defined PER mode).
Lastly, enter the known or required Advertising Interval duration of the BLE DUT.
Before we run the TAP software again,
click on this instrument initialization button,
so that the instrument initialization step can be excluded every time we run the software.
Run the TAP software one more time.
And you can see that since we have enter a number of fix settings
the overall test time is significantly reduced
from about one minute to less than 40 seconds.
Thank you for watching this video.
