The USB‑5681 features a wide dynamic range and high measurement accuracy packaged in a size similar to a typical power head. As a true RMS power meter, the USB‑5681 is ideal for making extremely accurate average power measurements of signals ranging from single-tone and multitoned sources to wideband, complex digital waveforms. The USB‑5681 is highly suitable for mobile applications or adding to automated test applications to free up valuable rack space without sacrificing performance. The USB‑5681 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.
