Feature: 1. Wide Frequency Coverage High Output: The spectrum analyzer supports ultra wide frequency ranges from 100kHz to 5.3GHz, covering comprehensive analysis needs from low to high frequency. As a handheld high frequency signal generator, it provides sinewave outputs from 100kHz to 800MHz, squarewave outputs from 800MHz to 4.4GHz, and frequency mixing signal outputs from 4.4GHz to 5.4GHz to meet diversified requirements. 2. High Resolution Low Noise Performance: 200Hz to 850kHz adjustable resolution bandwidth (RBW), RBW design as low as 200Hz can effectively differentiate adjacent signals to meet SSB two tone intermodulation test requirements, and the 850kHz RBW realizes fast scanning. In addition, the background noise level (DANL) is as low as -166dBm/Hz, and with the built in low noise amplifier (LNA), it can distinguish signals as low as -140dBm at 200Hz RBW to ensure measurement accuracy. 3. Intuitive and Convenient Control Experience: The built in 4inch TFT touchscreen provides a more intuitive data display and simplifies the operation process, which makes on site analysis and setup easy and fast. The device is equipped with a 3000mAh high capacity battery, allowing for up to 8 hours of continuous work to meet the needs of long time outside measurements. It also supports saving screenshots directly to a memory card. 4. Flexible Data Management Expandability: The device supports PC and APP connections, allowing for wireless data transmission and real time synchronized display on the computers, improving work efficiency and flexibility of analysis. The support for a memory card further expands the storage space, which makes it easy to save a large amount of data for subsequent analysis. 5. Innovative ULTRA Mode Adaptability to Multiple Scenarios: The ULTRA mode extends the upper limit of the spectrum analyzer to 5.3GHz. Combined with the stable performance from 100kHz to 800MHz in the normal mode, it demonstrates superior application value and high adaptability in various fields such as communications, electronic research and development, educational experiments, etc. Specification: Name: Spectrum Analyzer Material: plastics Battery: 1 x 3.7V, 3000mAh li polymer battery (included) Display: 3.95inch TFT LCD 480x320 Maximum onput frequency: sinus up to 800MHz, squarewave up to 4.4GHz Output level: -104dBm to -16dBm Ultra mode: level calibrated up to 5.3GHz Internal LNAgain: 20dB up to 4GHz Displayed points per scan: maximum 450 0-350MHz scan time: 165ms DANL at 100MHz: -153dBm/Hz(LNA Off) / -169dBm/Hz (LNA On) DANL degrading in ultra mode: 10dB above 2.5GHz, 25dB above 5.3GHz Phase noise at 10kHz offset: -92dBc/Hz Phase noise at 100kHz offset: 110dBc/Hz IIP3 without LNA: +18dBm (at least 2MHz apart) /OdBm (500Hz apart) IIP3 with LNA: -8dBm (at least 2MHz apart) Frequency stability: <1ppm (-10℃ to +55℃) Audio out: 3.5mm headphone plug FW update mode activation: Push jog button before switch on Maximum current consumption: 330mA Maximum charging current: 1300mA Communication interface: Type C, UART-TTL (2.54mm Connector) Item size: 117x 72 x 23mm / 4.61 x 2.83 x 0.91in.
