SPM Controller for developers
PC based digital dual-core SPM controlling system with
- 8 channels @ 24 Bit D/A channels
- 8 channel @ 24 Bit A/D channels
- LCD displays for four A/D and four D/A channels
- line sync and image sync output
- control of up to three stepper motors for the coarse approach
- 19" rack-mount housing (110 V or 230 V power supply)
For the coarse approach, we provide many alternative options:
slip stick movements, steppers in x- and y-direction, ...

Each
controller includes:
- modern dual-processor PC
in 19” rack server
housing with
TFT monitor
- PCI-card interface
with SXM-DSP for data exchange between PC and controller &
lockin amplifier
- an open
source software under Windows XP Prof., which supplies all basic
functions
for any SPM application but is also suitable for other
applications.

Selected Features (see also Software):
- simultaneous
acquisition of almost unlimited number of pictures
(limitation starts for example at 20 pictures with 512 pixel due to the
PC)
- integrated
distance control (IP controller) with over 6 different feedback modes
- slope
correction during
scan
- free
parameter input
during scan
- 4
different types of
spectroscopy (any signal vs. distance, any signal vs voltage, ...)
- computer
controlled
coarse positioning and automated approach
- adapable
to almost all
hardware due to
- free
scalabity
of all channels in physical units
- offset
correction for
each hardware channel
- sign
inversion possible
- relation
between
hardware channel and name is open
- additional
adjustment
for user specific setups:
- number
of steps for
stepper motor approach,
- delays
and repeat times
for slip stick controls

Optional
features
- components for the mechanical movement of
tip
or sample:
- Slip-stick power supplies and controls
with
adjustable parameters or
- stepper motor drivers for x-, y- and z-
direction or
- three stepper motor drivers for vertical
direction (levelling of a SPM head)
- additional digital LockIn amplifier on the
PCI
card → dual reference mode available !! NEW !!
- high-voltage amplifiers
