1. A system for use with multiple electrodes coupled to respective spines of a probe, the system comprising:
multiple switches connected to the electrodes and configured to short different respective first subsets of the electrodes to each other and different respective second subsets of the electrodes to each other per different respective settings of the switches; and
a processor, configured to:
control the switches so as to alternate through the settings;
for each of the settings, cause a power generator to apply a voltage between the shorted first subset of the electrodes and the shorted second subset of the electrodes; and
in at least one of the settings, cause the switches to short at least one respective first subset of the electrodes or one respective second subset of the electrodes to the spines to which the respective first subset of the electrodes or the respective second subset of the electrodes are coupled.
