Abstract
Voltage measurement with a particle probe without external trigger signal. Methods and apparatus are provided for voltage measurement with a particle probe without an external trigger signal of a signal having at least one fixed frequency, fs. The known arrangements for voltage measurement with an external trigger signal remain fundamentally unaltered; however, the required trigger signal is derived from the measured signal itself.
