USB-5680 Image


The USB-5680 from National Instruments is a USB true RMS power sensor that operates from 50 MHz to 6 GHz. It has a dynamic range from -40 to +23 dBm. The device draws only 150 mA from the USB connection, making it highly suitable for mobile applications or adding to automated test applications to free up valuable rack space. It measures the power of continuous wave signals, ranging from single-tone and multitoned sources to wideband, complex digital waveforms. This power sensor has a measurement speed of up to 15 samples/sec and can also measure path loss in automated test applications.

The USB-5680 can be hardware-triggered through an external trigger source or software-triggered based on the signal source. Scope and slot modes use this software triggering to measure burst waveforms, such as WiMAX and LTE, and multislot waveforms, such as GSM and EDGE.
