USB-5684

The USB-5684 from National Instruments is a USB true RMS power sensor that operates from 10 MHz to 18 GHz. It has a dynamic range from -60 to +20 dBm. The device draws only 450 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 is ideal for making extremely accurate average power measurements of signals ranging from single-tone and multitoned sources to wideband, complex digital waveforms. 

This power sensor 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.
