| Description
The VSA™-1225 hardware module attaches firmly to HP iPAQ hx2400-series
and hx2700-series handheld computers to form a compact, extremely
portable instrument. The iPAQ supplies the computing power and 128 MB of
data storage, while the Datastick® VSA hardware module supplies the
sensor power and interface. SD (Secure Digital) memory cards — up to 2
GB each — provide virtually unlimited auxiliary storage.
The VSA hardware modules each have a standard BNC connector and a
very low-noise input that accommodates and powers almost any ICP®-type
piezoelectric accelerometer or ICP-type velocity sensor.
Power
The VSA modules have internal rechargeable Li-ion batteries and
advanced power management capabilities that typically stretch the
VSA-1225 to go a full shift or longer.
An optional 4800 mA/h rechargeable external bettery pack is available
if you need more power, and it gives you the added benefit of powering
or recharging BOTH the VSA module and the iPAQ handheld computer.
