1. Ultraprecise frequency analysis: Achieve exceptional signals with manually selectable resolution filters of 3, 10, 30, 100, 300, and 600 kHz. This spectrum analyzer is equipped to detect even the weakest signals, up to 102dBm, ensuring you never miss critical information in your measurements. 2. Speed, Resolution Performance: Experience seamless realtime scanning at an impressive speed of more than 1000 points per second at the resolution. Choose between 145 or 290 measurement points for detailed visualization, supported by a 2.8inch display with 320 x 240 pixels, and benefit from improved accuracy thanks to the automatic optimization of the device's scan points. 3. Versatile Input UserFriendly Interface: The analyzer supports a wide input frequency range from 100KHz to 350MHz, with 50ohm input impedance and both manual and automatic input attenuation in 1dB increments from 0dB to 31dB. User control is optimized by an intuitive resistive touchscreen, switch controls, and serial USB port connectivity. 4. Durable Construction Advanced Protection: Made of metal and ABS materials, the latest upgraded version (V0.3.1E) includes enhanced ESD protection on the ports and a linear power supply to minimize noise. The four different input/output modes of the analyzer ensure reliable performance and accurate signal evaluation in any environment.
