LTDZ 35M-4400M Handheld Simple Spectrum Analyzer Measurement of Interphone Signal
LTDZ 35M-4400M Handheld Simple Spectrum Analyzer Measurement of Interphone Signal Introduction: This product uses the local oscillator signal and the external test signal to obtain the difference frequency signal, and calculates the amplitude of the external test signal through the detector. Using a high-precision VCO source, the heterodyne signal frequency can be measured very accurately. Since the scanning range is very large (35M-4400M), because there is no special detection circuit for the external measurement signal due to cost and other factors, the measurement amplitude may have errors. Therefore, the product increases the magnification and displacement parameters, and the user can adjust the display waveform by himself. The amplitude display is adjusted and calibrated. Feature: 1. Adopt stm32f407 single-chip microcomputer (main frequency 168M) + 4.3 -inch TFTLCD (480*800) color LCD screen. 2. Full aluminum alloy housing + rotary encoder control. 3. USB powered, full English display. 4. Spectrum display range: 35M-4400Mhz; input impedance: 50 ohms. 5. RBW: 10khz, 50khz, 100khz, 200khz, 500khz, a total of 5 gear positions can be adjusted. 6. Screen scan points: 700 points. 7. Scanning span: 7M (10Khz), 35M (50khz), 70M (100Khz), 140M (200Khz), 350M (500Khz). 8. dBm range: -80dB -----10dB (support manual adjustment of calibration amplitude), the unit does not have an amplifier circuit inside, if you need to measure small signals, you need an external amplifier. 9. Maximum access signal: 10dB. 10. Working mode: Superheterodyne scanning spectrum analyzer, single scan time is 800ms. 11. Internally integrated lithium battery charging circuit, due to logistics safety reasons, this product is shipped without battery. By default, USB is used to supply power. Customers can add lithium batteries by themselves (providing instructions for installing lithium batteries). 12. Product specifications: 145mm*70mm*30mm. Weight: 200g. 13. Scope of use: walkie-talkie, toy remote control, 2.4G wifi. x Package Includes: 1 x Handheld Simple Spectrum Analyzer 1 x USB cable (No antenna included)

Simply speaking, it is just like a USB disk to copy file, very convenient. However, if you are inconvenient to use the computer, you can purchase the OTG adapter or OTG cable, so you can connect to the phone to download songs. When purchasing an OTG cable, please check the interface of your mobile phone (Android or Tyoe-c or Apple) and select the corresponding OTG product.

Our lab tests have a play time of 8-12 hours, which fully meets the general outdoor sports needs. If you have any dissatisfaction, we support seven days no reason to return, one year warranty, please rest assured to buy. Thank you for your understanding and support. Waterproof Mode: Please use the black waterproof earcap (as standard accessory) when you are running/fitness. Our headphone waterproof level is ipx8, although the waterproof level is relatively high, usually accidentally dropped into the water, or sweating when sproting, and even occasionally washed with running water, as long as the water is dried in time, pay attention to maintenance, the earphone will be no problem. However, experts do not recommend swimming for too long time, especially when diving. When you take a break on the shore, there is no problem at all. Because of the double pressure of water temperature and water pressure in winter, and the disinfection powder in the water of the swimming pool, it is easy to damage the invisible rubber pad inside the earphone, so that it is easy to enter the water after a long time, resulting in internal damage. Thank you for your understanding and support.
