THE SIGNAL MODULES
62
The calibration of the monitor signals can be found by looking up the sig-
nal calibration in the Scan Head Calibration Dialog, reached via the menu
‘Options>Config Scan Head...’. The magnitude of the physical signal can
be calculated from the Monitor Signal voltage using the formula:
In addition to the monitor voltages, +15V and -15V voltage sources are
available for driving small home-made electronics. The voltages are availa-
ble on a three-pole mini-DIN connector. The pin-out of this connector is
shown in figure Voltage source connector:
Signal Module: A
The Signal Module: A can be used for adding functionality to the easyScan
2 system in addition to the applications fo the Signal Module: S. The sig-
nals are available on twenty-one BNC connectors that are labelled with
Amplitude The measured cantilever vibration amplitude.
Phase The measured cantilever vibration phase. The phase is
affected by the Reference Phase Mode Property setting of
the Phase Contrast Mode.
Voltage source connector: Connector as seen from outside.
