(a) Modulation signal of a 1 Hz square wave. The low level corresponds to a pressure P1 on the sample and the high level to P2 (P1 > P2). (b) Schematic diagram of a DiffEXAFS measurement. The square wave is divided into two parts: one part controls three PZTs, the other is a reference signal of the signal analyzer. The EXAFS spectra at P1 and P2 are obtained simultaneously, and their difference gives the DiffEXAFS spectrum.
