With 4” IPS-TFT LCD (480×320) display can show a maximum of 450 points per scan, clearly presenting signal details and measurement results. Supports PC control, enabling easy data transfer and analysis
• Ultra-Wide Frequency Range: The TinySA Ultra+ ZS407 Spectrum Analyzer covers a frequency range of 0.1 - 900MHz, with Ultra mode enabled up to 7.3 GHz, level calibrated up to 7.3GHz. Can observe signals up to 12GHz, which represents a significant improvement over previous models. It can accurately capture and analyze a broader range of signals, making it suitable for a variety of complex RF testing scenarios
• Powerful Signal Generation Capability: The Tiny sa Ultra+ ZS407 can act as a Signal Generator with sine wave output between 0.1 MHz and 900 MHz, square wave output up to 6.3 GHz, or RF test signal output up to 7.3 GHz. It has a rich variety of signal generation types and a wide frequency range
• Long-Lasting Battery: Equipped with a Li-polymer 3.7V 5000mAh battery, the battery life is significantly increased compared to previous models. It can meet the needs of continuous testing for a long time or outdoor operations, reducing the inconvenience of frequent charging and improving work efficiency. Built-in 32GB micro SD card, solving the on-site data storage issue, convenient for data sharing and storage
• High-Gain Low-Noise Amplifier (LNA): The internal LNA gain can reach 20dB up to 7.3GHz, effectively enhancing the reception ability of weak signals. At the same time, at 100MHz, the DANL is as low as -169dBm/Hz when the LNA is on, reducing noise interference and improving the accuracy of signal measurement
• Excellent Phase Noise Performance: The phase noise is -100dBc/Hz at a 10kHz offset and -103dBc/Hz at a 100kHz offset. The low phase noise indicates high signal purity, enabling more accurate analysis of signal frequency stability and spectral purity. It is crucial for high-precision RF measurement and communication system performance evaluation
