We present the first results from Karl G. Jansky Very Large Array (VLA)observations as a part of the Fundamental Reference Active Galactic Nucleus(AGN) Monitoring Experiment (FRAMEx), a program to understand the relationshipbetween AGN accretion physics and wavelength-dependent position as a functionof time. With this VLA survey, we investigate the radio properties from avolume-complete sample of 25 hard X-ray-selected AGNs using the VLA in itswideband mode. We observed the targets in the A-array configuration at $4-12$GHz with all polarization products. In this work, we introduce our calibrationand imaging methods for this survey, and we present our results and analysisfor the radio quiet AGN NGC 4388. We calibrated and imaged these data using themulti-term, multi-frequency synthesis imaging algorithm to determine itsspatial, spectral and polarization structure across a continuous $4-12$ GHzband. In the AGN, we measure a broken power law spectrum with $\alpha=-0.06$below a break frequency of 7.3 GHz and $\alpha=-0.34$ above. We detectpolarization at sub-arcsecond resolution across both the AGN and a secondaryradio knot. We compare our results to ancillary data and find that the VLAradio continuum is likely due to AGN winds interacting with the localinterstellar medium that gets resolved away at sub-parsec spatial scales asprobed by the Very Long Baseline Array. A well-known ionization cone to thesouthwest of the AGN appears likely to be projected material onto the undersideof the disk of the host galaxy.
