Built-in Calibration Signal Generator - When not using an analyzer, this unit can serve as a signal generator - Outputs include MF/HF/VHF sine wave from 0.1 MHz to 350 MHz and UHF square wave from 240 MHz to 960 MHz - Designed for automatic self-test and low input calibration Input Frequency Range - Two inputs available - MF/HF/VHF input: 0.1 MHz to 350 MHz (high quality) - UHF input: 240 MHz to 960 MHz (lower/secondary) PC control and connectivity - Connects to a PC via USB - Uses serial over USB protocol (CDC) with a large command set - Driver is automatically downloaded when a connection is established ESD protection function - Version 3.1 includes an enhanced ESD protection feature - Diodes provide improved sensitive response, better antistatic performance, and longer service life Use scenarios - Laboratory RF path testing and calibration: use the built-in generator to validate MF/HF/VHF and UHF paths, perform automatic self-test, and calibrate low input signals without external equipment - Field maintenance and troubleshooting: generate test signals on site to diagnose RF front ends and connectors without carrying additional instrumentation - Automated PC-driven workflows: leverage USB CDC control for batch testing and automated calibration routines through software commands
