1. Product introduction:
ZJSC-XH108T handheld wireless signal detector (hereinafter referred to as 108T detector) is a device that scans the frequency and field strength of radio signals in a specific area. It can simultaneously measure the full wave strength of the 10MHz to 10GHz frequency band and the signal strength of 10 specific communication frequency bands, and present these 11 signal strengths in the form of histograms on the screen of the 108T detector in real time. When the signal strength exceeds the setting When the threshold is set, an audible and visual alarm is generated to remind the staff of abnormal signals.

2. Equipment structure:
The 108T detector has excellent mechanical performance, uses high-quality aluminum alloy housing, has a strong structure, and is resistant to falling and bumping; the hand-held part is designed with a rubber handle, which is non-slip and anti-dropping, ensuring the usability in harsh external natural environments; the front panel has four LED indicators and A 7-inch color touch screen, as a window for human-computer interaction, can present various status information, complete parameter settings, and display the signal strength of 11 channels in real time. The operation is simple and intuitive.
The top of the 108T detector can be connected to the full-band antenna, ISM directional antenna (2.4GHz and 5GHz) and the three antennas of the mobile phone signal antenna; there is a 5V DC power interface at the bottom left, which can be used with a power adapter, and a built-in 3200mAh lithium battery can be used. For the detector to work for 3 hours without power; the lower right provides a USB2.0 interface, the staff can insert the U disk, export the log file generated by the detector for a long time.
The top of the left and right handles of the 108T detector are respectively provided with an infrared emitting port and a power button. The infrared emission window can remotely control the mobile phone signal jamming equipment (need to be purchased separately), activate the mobile terminal in the standby state, force it to increase the transmission power, and facilitate the signal detection of the detector. The power button is the hardware switch of the tester. When pressed, the device is powered on, and when it is turned on, it is powered off and shut down.
The 108T detector has a compact structure, sturdy and durable, detachable external antenna, light and portable, rich interfaces, touch panel to complete man-machine interaction, simple operation.

Three, a variety of use environments
The 108T detector adopts an aluminum alloy shell, which is sturdy and durable. It uses industrial-grade components inside. It can work stably and reliably in harsh internal and external environments. It can complete meeting rooms, offices, warehouses, hospitals, prisons, etc. that need to detect radio signals. Inspection work in specific places.
It detects 10 signal types, including mobile phone frequency bands and WiFi and Bluetooth signals of all the three major domestic operators. It can find the signal emission sources in these specific places to ensure the quiet and safe radio environment of the communication frequency band.
The 108T detector can also be used to detect wireless signal emission sources in vehicles. For the possible eavesdropping, eavesdropping, and location tracking devices in vehicles, these devices need to communicate with the control terminal through a public wireless channel, and the 108T detector can detect the wireless communication signal and find the abnormal emission source to find out the hidden eavesdropping Pleasure device.

Four, simple human-computer interaction interface
The front of the 108T detector uses a 7-inch touch color LCD panel as the interface for operation and presentation, which can display relevant signal strength information, and directly perform parameter setting and function control with fingers. The operation is free and concise. At the same time, there are 4 LED indicator lights on the upper right of the display panel, from left to right respectively indicate the equipment working breathing light, detection status indicator, equipment power-on indicator and charging indicator.
Press the power button on the upper right of the device, the device is powered on, the blue device startup indicator LED lights up, and the welcome message on the main interface flashes, you will enter the interface shown in Figure 3, showing the main interface of the 108T detector.
The right side bar of the display panel is composed of the date and time information bar at the top, the ABS status bar, the main menu bar and the detection function start button at the lower right corner. The date and time information bar displays the current date and time information, which can be revised in the parameter settings; the ABS status bar indicates the current wireless signal strength display mode, with ABS mode (adaptive range) and non-ABS mode (fixed range) options, It can be modified in the parameter setting main menu.

Parameter setting page of LCD interface

The main menu includes parameter settings, log management and signal detection. The parameter setting interface includes six sub-functions including date and time modification, threshold parameter adjustment, log file management, alarm sound shutdown, automatic range (ABS) function, and log recording period. All operations are completed by intuitive touch on the touch screen.
"Date and Time Modification" can adjust the date and time information in the device, and "Alarm Sound Off" can determine whether the device will sound an alarm when an alarm occurs.
"Automatic range (ABS) function" decides to turn on or off ABS (automatic range field strength detection). When the ABS mode is turned on, the signal strength histogram displayed on the signal detection interface uses the adaptive range, which selects the most suitable range according to the signal strength; when the ABS mode is turned off, the signal strength histogram is displayed as a fixed range and will not change with the signal strength To adjust the range value of the histogram.
"Threshold parameter adjustment" includes full-band detection threshold and communication signal detection threshold. Full-band threshold refers to the threshold of 300MHz to 10GHz full-wave signal detection strength, and communication signal detection threshold refers to the signal threshold of 10 mobile phone frequency bands and ISM frequency band. When the detected radio signal exceeds the set threshold, the 108T detector will generate an audible and visual alarm.
"Log file management" can back up or delete the recorded log to facilitate the entry of test results and fill in the test report in the future; "Log record period" can set the period of log file generation, 108T detector will detect the signal The detection information is recorded in a set period and stored in the device for subsequent analysis and reading.
Five, rich signal detection types
The signal receiving sensitivity of the 108T detector can reach -105dBm, the detection coverage area radius is about 10 meters (the actual detection range also depends on the signal strength and background noise environment and other conditions), by configuring a high-gain antenna (additional purchase), the area radius can be Extend to 50 meters.
The detector can detect the full-wave signal strength of electromagnetic waves in the 10MHz to 10GHz frequency band, and can detect mobile communication signals (domestic) and WiFi and Bluetooth signals (ISM frequency band) of mobile phones through band-pass filters to achieve the radio signals in 11 Detection, including full band, CDMA800M, GSM900M, GSM1800M, TD-LTE B38, WCDMA/CDMA2000M/FDD-LTE, TD-SCDMA, TD-LTE B40, TD-LTE B41, and WiFi and Bluetooth working frequency bands ISM 2.4G and ISM 5G.
