WiFi Test Tips 14: Introduction to True MIMO Connection
True MIMO is one of the current mainstream WLAN three MIMO test schemes. True MOMO supports both TX and RX tests of DUT, and can complete all index tests of TX and RX.
WiFi Test Tips Seventeen: Spectrogram
Out-of-band interference: The interference caused by harmonics or spurious radiation outside the passband of receiving useful signals is called out-of-band interference.
One of WiFi test tips: the usage of Full packet
When testing WiFi signals, I often encounter the confusion of "Do I need to turn on Full Packet"
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 tips ten: how to send custom waveform files
In the PER test, you can use the built-in waveform file of the Meter software; but sometimes it is necessary to send some custom waveforms, then how to load the custom waveform file with Meter? Does Meter support wave files in those formats?
Wi-Fi Test Tips 13: Introduction and advantages and disadvantages of three MIMO tests
The current mainstream WLAN tests now support three types of MIMO tests. The three types of MIMO are: True MIMO, Composite MIMO, and Switched MIMO.
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.
