1. A method comprising:
determining a measurement plan comprising one or more acoustic measurements;
lowering, in a borehole penetrating a subsurface formation, a toolstring having one or more phased array modules, wherein each phased array module comprises:
a plurality of acoustic transducers operable to emit an acoustic excitation signal and receive an echo signal; and
a programmable circuit configured to set one or more variables of the phased array modules;
configuring, while the toolstring is in the borehole, at least one of the one or more phased array modules by programming the programmable circuit to set variables of the configured one or more phased array modules according to the measurement plan;
performing the one or more acoustic measurements of the measurement plan using the configured one or more phased array modules; and
characterizing one or more of the formation, a casing disposed in the borehole, and/or an annulus between the casing and the formation, using results of the performed one or more acoustic measurements.
