The Voltage Capture System (VCS; Tremblay et al. 2015) provides access to high time and frequency resolution voltage data from the MWA. The data recorded are the critically sampled voltages streaming from the fine-PFB stage of the standard MWA signal chain (i.e. before the correlator), thus the data have 100 μs time resolution and 10 kHz frequency resolution.
The primary science driver for the VCS is pulsars, though there are also opportunities in terms of Solar science (e.g. solar bursts, interplanetary scintillation) and other transient science cases where high time resolution is desirable (e.g. triggering on GRBs, FRBs and other exotic phenomena).
