This code has been tested and works for any kind of HSDC data. Indepedant if 1, 2, 3 or 4 datachannels are saved. It separates the MHz data and the kHz data in different data-arrays. The file is a zip file, containing 3 m-files. The main code is readHSDC(filename). The way to introduce this code in MatLab is as; [DataMHz, DatakHz, TimeMHz, TimekHz]

Hi Christopher, In normal ramping mode, giving a surface delay, measn indeed as Mike says a constant height (of the z-sensor) and you can measure the deflection variation by strip chart. If you howver go into the PicoForce software, there you can create a specific script and really do force-clamping (keeping the deflection (=load) constant during a

An extra comment to Mike's last statement about reduced modulus range with a single probe; It is indeed so that the probes spring constant needs to be selected depending on the sample at study for proper quantitfication of sample modulus. However, since regular probes can be used for PFQNM (in stead of asymetrical probes for HMX) a very broad range

Hi Sean, Same rules will apply as with classical nano-indentation. If the penetration depth gets relatively larger, the more effect of the underlying substrate will be influencing the modulus measurement. For this reason you have to keep the penetration depth (deformation channel with the PFQNM mode) low. A good rule is to keep the deformation only
