Lock-In Amplifier - JEOL JSPM-5200 Instructions Manual

■ Setting Channel A
This software oscilloscope enables you to acquire and display data from two channels at
the same time. Channel A is displayed in red, and Channel B in blue. Normally, set
Channel A to Topography (motion in the Z direction of the scanner). The setting of
Channel B differs depending upon the scanning mode (Contact mode, AC Mode, STM,
etc.), so refer to the respective operation methods.
The procedure for setting Channel A is as follows:
1.
Click on the Source
menu.
2.
Click on the Coupling
3.
Click on the Sensitivity
menu.
4.
Double-click on the Offset numerical value input box, and enter 0.0 using the
keyboard.
5.
Once you have completed settings, select File from the main menu, and then
select Store Configuration from the pull-down menu to save the set values.

Lock-In Amplifier

This optional lock-in amplifier expands the application of the system, enabling you to
perform the following measurements:
• Viscoeleasticity measurement
• Lateral modulation friction force measurement
• SKPM (Scanning Kelvin Probe Microscopy) measurement
• Electrostatic force measurement
The Model 7265 lock-in amplifier is needed when you perform electrostatic force
measurement.
