DSPEC LF is a member of the DSPEC USB family of digital technology gamma-ray spectrometers from ORTEC. It provides the same rock
solid spectral stability with variation in temperature and count rate and retains many of the valuable attributes of the other two models.
Many environmental and radiochemistry laboratories will find this instrument to be the best MCA for day-to-day sample counting with
laboratory HPGe or NaI detector systems.

SMART-1™ Support for Quality Data — all the time, every time

ORTEC's unique SMART-1 detectors are indeed smart. They monitor and store the detector state-of-health (detector temperature, preamp
power, bias over range, bias on/off state). A single check by the DSPEC LF will verify the detector is ready and remains ready to perform
acquisition. During acquisition, the SMART-1 detector continually monitors the state-of-health (SOH) to ensure the integrity of the acquired
data. At the end of acquisition a quick check of the SOH flag in the SMART-1 detector shows if any parameters deviated from specification
during the measurement. This is vitally important for environmental samples that must be counted for long periods of time and regulatory­driven samples where data integrity is important.

Another big advantage is the SMART-1 detectors have the recommended bias value preset at the factory. You no longer have to look
through paperwork or for tags on the detector to find the right bias setting. Simply turn on the DSPEC LF and the SMART-1 detector
automatically senses the detector temperature, determines the right high voltage bias, and turns it on.

Fast PC Interface

The DSPEC LF gives you high speed control over standard USB. The plug-and-play feature makes installation simple. A nearly unlimited
number of DSPEC LFs can be connected simultaneously using USB hubs. As an ORTEC CONNECTIONS compatible instrument, the
DSPEC LF works in a networked and in a stand-alone configuration. ORTEC CONNECTIONS means: any hardware, any software, anywhere
in the laboratory with full seamless control and built-in security.

Simple, Single-Cable Connection to Detectors

The DSPEC LF uses the unique ORTEC DIM (Detector Interface Module) to connect the DSPEC LF and the detector with only a single
cable. The DIM provides for bias close to the detector so that only signal and low voltage power are carried in the cable. No longer is high
voltage bias and the dangers associated with it carried over long distances.

Monitor Vital Values

The DSPEC LF shows the values you need on the front panel LCD display. The DSPEC LF displays the instrument ID, name, serial
number, preset count conditions, current live and real time, dead time percentage, input count rate, HV status and value, and the serial
number for SMART-1 detectors.

Small Size

Smaller than a sheet of paper, the DSPEC LF sits right on the desktop. Lightweight and rugged, multiple DSPEC LFs can be stacked on
top of one another via their interlocking cases without fear of sliding or tipping.
