Piezoresponse with the NanoScope V Generic Lock-Ins

The NanoScope V Controller has three built in lock-ins. Lock-ins 1 and 2 are high-speed lock-ins that allow operation up to 5 MHz, and lock-in 3 is a low speed lock-in that allows operation to 50 kHz. The high-speed lock-ins have a minimum lock-in bandwidth of 500 Hz and the low speed lock-in has a minimum lock-in bandwidth of 5 Hz. The three lock-ins can be accessed using the Generic Lock-in interface.

To open the Generic Lock-In interface, select Microscope > Generic Lock-In from the main menu.

NOTE: The Drive Output and Lock-In Input controls can also be accessed in the Parameter list. They will be set to the default values for the workspaceA collection of views and parameters organized for a specific imaging mode. Workspaces create an environment tailored to the selected imaging mode and give the user a start in the right direction toward optimizing imaging parameters. in which you are operating.

The interface allows you to route the drive signals to different sections of the microscope. For example, the drive can be routed to the X piezo drive, Y piezo drive or Z piezo drive. For Piezoresponse operation in Contact Mode, route the drive signal either to the sample or the tip. To enable drive routing to either the tip or the sample chuck, first enable the same in the scan parameter list under Other parameters: Other > Sample Bias Control > Sample Bias.

The Generic Lock-In control window is necessary for performing PFM Vertical and Horizontal Domains Operation.
