# flowRS's bench for the test-station template (flowrs_station::spec::TEMPLATE), simulated: a
# Rigol DP832 powering a power board, a meter on the board's 1.2 V core rail, a relay matrix in
# front of a second meter that scans the board's test points, and a scope on the rail's ripple.
# Written for flowRS (Apache-2.0); the format is spec/flowrs-bench-sim-1.md.
#
# The supply and the first meter are catalogue instruments (`model`): every line the catalogue
# defines for them is answered (a setpoint reads back what was set), and the file adds what the
# catalogue's mock cannot: an output that settles in 30 ms after it changes, a board that draws
# current as a resistive load and holds its rail with a regulator, noise from fixed seeds.
