1. Builtin Calibration Signal Generator If an analyzer is not used, it can function as a signal generator with two frequency outputs: an MF/HF/VHF sine wave output for 0.1MHz–350MHz and a UHF square wave output for 240MHz–960MHz. It is designed for automatic selftesting and lowinput calibration. 2. Input Frequency Range This analyzer features two inputs—a quality MF/HF/VHF input for 0.1MHz–350MHz and a lowerperformance UHF input for 240MHz–960MHz. 3. PC Control The analyzer can be connected to a PC via USB, supporting the serialoverUSB protocol (CDC) to access a wide range of commands. Upon connection, the driver is automatically downloaded. 4. ESD Protection Function The latest Version 3.1 introduces an enhanced ESD protection function with installed diodes, delivering more sensitive response performance, higher antistatic efficiency, improved quality, and extended service life.
