The NI USB-5680-01 RF Power Meter with True RMS is a compact instrument for precise RF power measurements across 50 MHz to 6 GHz. It delivers true RMS detection for accurate readings of complex modulated signals and operates directly from USB power, eliminating external power supplies. The dual-path architecture provides 63 dB dynamic range, making it suitable for portable deployments and space-constrained automated test systems. The bundled 198506-01 USB cable (1 meter, Type A to Type B jackscrew) enables immediate integration into test environments.
