[0002] In the same electronic product, Bluetooth and 802.11b / g / n both work in the 2.4G frequency band and may interfere with each other. One of the typical applications of interference is VOIP, where you use the WLAN of your mobile phone to make a VOIP call and use a Bluetooth headset to make a call. The consequence of mutual interference is that users can feel a decrease in call quality. There are some design methods that can reduce mutual interference. The existing technology only does coexistence at the software level, and lacks hardware testing methods to verify the coexistence of Bluetooth and WIFI. There is a lack of data support for hardware testing, such as the isolation between the two antennas of Bluetooth and WIFI, and whether it meets the requirements. If the isolation between the two antennas in hardware is not good, the result is that Bluetooth and WIFI will interfere with each other.

[0003] A vector network analyzer with an adjustment mechanism in Chinese patent publication number CN219173092U requires screws on both sides to be rotated respectively for fixing and releasing when adjusting the angle, which is cumbersome to operate and increases the burden of use.
