Abstract: Techniques for determining calibration data associated with a radio frequency (RF) testing environment are discussed herein. For example, an RF signal can be input to the RF enclosure and selectively applied to discrete attenuators. The attenuators can attenuate a strength of the signal and a signal strength can be measured by various user equipment (UEs) that are located within an RF enclosure. In some examples, a plurality of measured reference signal received power (RSRP) values can be determined by a plurality of UEs associated with a particular attenuation level. Different attenuation levels can be measured, and an average attenuation can be determined for attenuation steps. Measured attenuation steps can be extrapolated to other attenuation levels to expedite the calibration process. Then, a testing plan can be applied to the RF enclosure and the calibration data can be used to ensure accurate signals for testing UEs.

Abstract: Disclosed are welding systems and methods for conducting a completed circuit testing process. The welding system includes a power source to deliver power via one or more power outlets. Control circuitry receives an input to initiate a welding process and to command the power source to deliver a power signal with a current below a threshold level. The control circuitry monitors characteristics of the power signal at the one or more power outlets and determines whether a completed circuit condition exists. The control circuitry performs this determination based on information obtained through monitoring the characteristics of the power signal. The control circuitry controls the power source to prevent delivery of power if a completed circuit condition exists.
