Microscope Specifications

1.3.3 Controller Electronics and Auxiliary Channels

The MultiMode utilizes a NanoScope Controller having a digital signal processor (DSP) with a
20MHz peak rate for arithmetic operations. The MultiMode is equipped with four auxiliary digital-
to-analog converters (DACs). Three DACs have ±10V outputs, and one DAC has a ± 12V and
±220V outputs; all four channels have 16-bit resolution.
In addition, there are two ±10V analog-to-digital converters (ADCs) having 14-bit resolution and
software-selectable filters. One ADC has four-way mutliplexing.
All Veeco SPMs may be attached to an optional Signal Access Module (SAM), which provides
direct access (via BNC connectors) to all input and output signals between the controller and the
microscope. Generally, the SAM is useful for customized use or modification of the SPM.
