ONSIDERATIONS
The Aurora-2 should be mounted in an environment that is as vibration-free as possible.
Sources of mechanical and acoustic vibration will decrease the Aurora’s maximum resolu-
tion capability. The Aurora-2 should be placed on a its own vibration isolation table.
Computer cooling fans and mouse clicks produce vibration that negatively impacts image
quality, so place the computer on a separate table. Basement or ground floor rooms are
better for the instrument, since multi-story buildings usually have significant vibration on
the upper floors. Temperature and humidity should be controlled to maintain constant en-
vironmental conditions. Normal indoor conditions, i.e., “room temperature” and average
humidity, are sufficient. Extremes of temperature and humidity will negatively affect the
instrument and possibly cause damage.

ONNECTIONS
CAUTION
Make sure the power is OFF to all the modules and the computer while
setting up. Connecting cables to powered-up electronics may damage the modules.
The cable connection diagrams (Figure 2-5 and Figure 2-6) show the configuration with
and without an external lock-in amplifier (a lock-in amplifier is also integrated into the I/O
MOD+ board). A photocopy of the appropriate diagram is useful for checking off the cable
connections as they are made.
