Bluetooth BT test knowledge one: the configuration instructions of the Bluetooth channel number
According to the Bluetooth protocol version specifications of different DUTs, from BasicRate (BR) of BT 1.0 to Enhanced Data Rate (EDR) of BT 2.0 to Low Energy (LE) that began to appear in BT 4.0. The Bluetooth Special Interest Group (SIG) maintains the core Bluetooth specifications and has been looking for expansion and balance on power consumption, speed, and the latest Internet of Things functions.

Wi-Fi test knowledge two: matters needing attention in the use of power splitter
In the Wi-Fi test, when the product antenna is greater than or equal to two, a power divider is usually used. There are two commonly used ones: 1 point 2, 1 point 4. It should be noted here that when measuring line loss and normal testing, the unused port must be connected to a 50Ω matched load.

Wi-Fi Test Tips 4: Why the instrument needs to be turned on and warmed up
I don’t know if you have noticed that basically all instruments involved in frequency and power accuracy measurement require a period of startup warm-up time. Why?

Wi-Fi test knowledge three: regular cleaning of the instrument dust net
When maintaining the instrument, when to clean and how to clean the dust-proof net are issues we are more concerned about.

Wi-Fi test knowledge five: Wi-Fi product test PER
PER is a mandatory item for mass production of WIFI products, because the mass production test can only verify whether the DUT's RX link is normal if it passes the PER test. However, various problems will cause packet loss during PER test. The following is an analysis of common situations.

Wi-Fi test knowledge six: the relationship between Trigger and Channel
Reference level: The maximum power value input from the DUT to the instrument. When the input power is greater than this value, the power result may be inaccurate.

Wi-Fi Test Tips Seven: Power ALL and Power Frame
Power Frame: The average power of the data frame, the average value of the red line in the figure below Power Frame:-10.73dBm

Wi-Fi test knowledge eight: the use of Auto Range
AutoRange will calculate the appropriate reference level by itself according to the signal's transmit power; if the Signal trigger mode is used, Auto Range will also calculate the appropriate trigger level to ensure that the instrument captures the complete frame header and ensures the accuracy of the analysis results Secondly, Auto Range will adaptively display the VSA result view (Fit to view) for easy observation.
