[0048] According to some embodiments of the present application, referring to Figures 1 to 8 , the present embodiment relates to a portable spectrum analyzer 100, comprising a host 1 and a display screen 2, the host 1 comprising a shell 11, a keyboard 12, a mainboard 13 and a spectrum module 14, the rear end of the shell 11 being provided with a radio frequency signal input interface 111, the keyboard 12 being installed on the top of the shell 11, the mainboard 13 and the spectrum module 14 being installed in the shell 11, the mainboard 13 being connected with the keyboard 12 and the spectrum module 14 respectively; the display screen 2 being hingedly connected with the rear end of the host 1, the display screen 2 being connected with the mainboard 13.

[0049] The top of the shell 11 is provided with a power key, which can turn on or off the host 1. The rear end of the shell 11 is also provided with a heat dissipation hole, a power line interface and a power display lamp. The host 1 is also provided with a battery.

[0050] The portable spectrum analyzer 100 is of a computer structure, and the spectrum module 14 is placed in a rugged computer, so that the portable spectrum analyzer 100 can be used in indoor laboratories and harsh outdoor environments, can be used as a standard receiver, can be used for conducted testing of transmitters, and can be used for open field testing of transmitters, radio monitoring and electromagnetic environment testing, etc. in cooperation with an antenna. At the same time, the spectrum data can be further processed through the mainboard 13 and the keyboard 12. The structure is simple and integrated, and is convenient to carry and use.

[0051] According to some embodiments of the present application, as shown in Figure 1 and Figures 3 to 5 , a first quick plug connector 112 is arranged on one side of the shell 11, and the host 1 further comprises an amplifier 15, which is quickly connected with the first quick plug connector 112.

[0052] In this way, the first quick plug connector 112 can be connected with the amplifier 15 according to actual conditions, and the amplifier 15 can amplify the input spectrum signal, thereby enhancing the signal strength received by the spectrum module 14. In some embodiments, the first quick plug connector 112 can also be used to connect a filter 16.

[0053] According to some embodiments of this application, optionally, such as Figure 1 and Figures 3 to 5 As shown, a second quick-connect connector 113 is also provided on one side of the housing 11, and the main unit 1 also includes a filter 16, which is quickly connected to the second quick-connect connector 113.

[0054] Thus, by providing the second quick-connect connector 113, a filter 16 can be connected as needed, and the filter 16 can filter the input spectrum signal. In some embodiments, an amplifier 15 is connected to the first quick-connect connector 112, and a filter 16 is connected to the second quick-connect connector 113. The filter 16 filters the input spectrum signal and then amplifies it through the amplifier 15, thereby enabling the spectrum module 14 to better filter out useless signals and receive useful signals.

[0055] According to some embodiments of this application, optionally, such as Figures 1 to 3 As shown, the main unit 1 also includes a handle 17, which is mounted on the front of the housing 11.

[0056] The inside of the handle 17 can be provided with an anti-slip texture to make it easier for users to hold. In this way, the handle 17 makes it easier to carry and use the portable spectrum analyzer 100, thus expanding its application range.

[0057] According to some embodiments of this application, optionally, such as Figure 1 , Figure 2 and Figure 5 As shown, the main unit 1 also includes four corner protectors 18, which are installed at the four corners of the housing 11.

[0058] The corner protectors 18 can be made of sponge or metal. In this way, by setting four corner protectors 18 to protect the four corners of the housing 11, the portable spectrum analyzer 100 is prevented from being bumped or collided during carrying.

[0059] According to some embodiments of this application, optionally, a data cable interface is also provided on the other side of the housing 11.

[0060] The data cable interface can be a LAN port, a USB 2.0 / 3.0 port, or an HDMI port. There are multiple data cable interfaces, including LAN, USB 2.0 / 3.0, and HDMI ports.

[0061] Thus, by setting up a data cable interface, host 1 can connect to external devices such as a mouse, memory, or host computer.

[0062] According to some embodiments of this application, optionally, such as Figure 2 and Figure 6As shown, the host 1 also includes a latch 194 stop and a cover assembly 19. The latch 194 stop is installed on the top of the data cable interface on the other side of the housing 11. There is a slot between the latch 194 stop and the other side of the housing 11. The cover assembly 19 includes a cover 191, a spring baffle 192, a slider 193 and a latch 194. The cover 191 is hinged to the bottom of the other side of the housing 11. The spring baffle 192 is installed on the cover 191. A sliding groove extending in the vertical direction is opened on the spring baffle 192. The slider 193 passes through the sliding groove and connects with the latch 194. The latch 194 is used to cooperate with the slot to open or close the data cable interface.

[0063] Thus, by setting the latch 194 to cooperate with the slot, the data cable interface can be opened or closed, thereby preventing dust from entering the data cable interface and affecting its use. In actual use, the slider 193 can be slid upwards vertically to engage the latch 194 into the slot, closing the data cable interface. When the data cable interface needs to be used, the slider 193 can be slid downwards vertically to release the latch 194 from the slot.

[0064] According to some embodiments of this application, optionally, such as Figure 6 As shown, the cover assembly 19 includes a cover sponge 195, which is installed on the inner side of the cover 191. On the other side of the housing 11, a first groove is provided in the circumference of the data cable interface. The first groove is used to accommodate the cover sponge 195.

[0065] Thus, the cover plate with sponge 195 provides cushioning and protection.

[0066] According to some embodiments of this application, optionally, such as Figure 1 and Figure 7 As shown, a second groove is provided on the top of the display screen 2. The portable spectrum analyzer 100 also includes a flip-button assembly 3. The flip-button assembly 3 includes a pivot pin 31, a flip-button 32, and a torsion spring 33. The flip-button 32 is hinged to the second groove through the pivot pin 31. The torsion spring 33 is sleeved on the pivot pin 31 and located in the middle of the flip-button 32. A buckle groove 114 is provided on the top of the front of the housing 11. The buckle groove 114 is used to cooperate with the flip-button 32 to lock or open the host 1 and the display screen 2.

[0067] Thus, by setting the flip-top 32 to cooperate with the latch 114, the main unit 1 and the display screen 2 are locked, making it easier to carry the portable spectrum analyzer 100. When needed, the cooperation between the flip-top 32 and the latch 114 is released, thereby opening the main unit 1 and the display screen 2.
