PD measurements in RF with a Vivaldi antenna as a consequence of a sudden voltage change. The data is sorted by the amplitude of the applied voltage. The data also include the voltage impulse applied on a twisted pair. All files include 50 events of the output of the antenna and the corresponding voltage impulses to have statistical reliability.
Six sets of .mat (Matlab) files with 50 samples of PD and voltage impulses sampled at 20 GSps. The time vector can be constructed with the sampling frequency and the number of samples.
The name of the files contains information on the voltage peak which helps to determine the activity of PD:
Vivaldi300A -> 300 means a voltage peak of 300V. 'A' means that the data is from the antena.
Vivaldi300V -> 'V' means that the data is for the voltage impulse.

This is the raw data used in the following paper: Martínez-Castilla, P., Gutiérrez-Blasco, I.M., Spitz, D.H., & Granot, R. (2021). The efficacy of music for emotional wellbeing during the COVID-19 lockdown in Spain: An Analysis of Personal and Context-Related variables. Frontiers in Psychology, 12:647837. https://doi.org/10.3389/fpsyg.2021.647837 The study aimed to analyze the impact of personal and contextual variables on the perceived efficacy of musical behaviors to fulfill adults’ emotional wellbeing-related goals during the lockdown established in Spain. Personal variables included age, gender, musical training, personality, resilience, and perception of music’s importance. Contextual variables referred to living in a region with a high COVID-19 impact, perception of belonging to a risk group, being alone, having caring responsibilities during confinement, and amount of time of music listening as compared to prior to the crisis. The study was conducted retrospectively during August–December and the answers of 507 adults were analyzed. Only personal, but not COVID-19 context-related variables, showed an impact on music’s efficacy.

Sus padres murieron siendo niño; pasó momentos muy difíciles, incluso de penuria. Estuvo viviendo algunos años en España. Trabajó en muchas actividades, con especial dedicación a la industria de la madera. También estuvo activo en el contrabando y el comercio, además de ser prestamista. Tras la guerra civil ganó bastante dinero con la carestía de determinados productos (p. ej. fitosanitarios) en España., Seus pais morreram quando era criança; viveu momentos muito difíceis, até mesmo escassez. Viveu alguns anos na Espanha. Ele trabalhou em muitas atividades, com especial dedicação à indústria da madeira. Também era ativo no contrabando e comércio, além de ser um credor. Após a guerra civil, ele ganhou muito dinheiro com o alto custo de certos produtos (por exemplo, produtos fitossanitários) na Espanha., His parents died when he was a child; he had very difficult moments, even shortages. He lived some years in Spain. He worked in many activities, with special dedication to the wood industry. He was also active in smuggling and trade, as well as being a lender. After the civil war he earned a lot of money with the high cost of certain products (eg phytosanitary products) in Spain.
