Product Overview

35M-4.4GHz Sweep Simple Spectrum Analyzer Signal Generator Tracking Source + LCD

Detail 

35M-4.4G Sweep simple spectrum analyzer,simple signal generator; USB power supply 



Specification:


1. Adopt stm32f407 single chip computer (main frequency 168m) + 4.3-inch TFTLCD (480 * 800) color LCD screen.
 
2. All aluminum alloy shell + rotary encoder control.
 
3. USB power supply, full English display.
 
4. Spectrum display range: 35m-4400mhz; input impedance: 50 ohm.
 
5. RBW: 10kHz, 50KHz, 100kHz, 200kHz and 500KHz are adjustable.
 
6. Number of screen scanning points: 700.
 
7. Scanning span: 7m (10kHz), 35m (50KHz), 70m (100kHz), 140m (200kHz), 350m (500KHz).
 
8. DBM range: - 80dB ----- 10dB (support manual adjustment of calibration amplitude). There is no amplification circuit inside the machine. If small signal needs to be measured, external amplifier is required.
 
9. Maximum access signal: 10dB.
 
10. Working mode: superheterodyne scanning spectrometer, single scanning time 800ms.
 
11. Internal integrated lithium battery charging circuit, due to logistics safety reasons, the product delivery does not include batteries. USB is used for power supply by default, and customers can add lithium battery by themselves (provide instructions for installing lithium battery).
 
12. Product specification: 145mm * 70mm * 30MM. Weight: 200g.
 
13. Scope of use: walkie talkie, toy remote control, 2.4gwifi.
 
14. At present, we accept the reservation and deliver according to the order. Because the aluminum alloy shell customization needs to be made according to the manufacturer's progress, and the shell can be made at least 15 days later, so we can't guarantee the delivery time. Please ask if there is any in stock before placing the order.
 
15. Other instructions: This product uses the mixing of the local oscillator signal and the external measurement signal to obtain the difference frequency signal, and calculates the external measurement signal amplitude through the geophone. Using high precision VCO signal source, heterodyne signal frequency can be measured very accurately. Because the scanning range is very large (35m-4400m), because the cost and other factors do not set a special detection circuit for the external measurement signal, the measurement amplitude may have errors, so the product has added two parameters of magnification and displacement, the user can adjust the display waveform by himself, and adjust and calibrate the amplitude display.
