Digital Filter Improves Resolution for Mechanically-Cooled Systems! The LFR is designed to remove microphonic noise from the output signal of high purity germanium detectors. What kind of results can you expect? If you have mechanically-cooled systems with degraded resolution, the LFR can improve your resolution significantly. Here are some examples. What Does the LFR Do? The LFR is a new digital filter that can improve the resolution of your system. The innovative design was developed specifically to remove periodic low frequency electronic noise from the output of high purity germanium...

DSP EC jr 2.0 FAST Communications with USB 2.0 Universal Serial Bus, or USB, is a computer standard designed to eliminate the guess work in connecting peripherals to your PC. With the DSPEC jr 2.0, ORTEC keeps your laboratory current with the fastest and easiest way to manage data transfer in the industry. With the introduction of USB 2.0, the standard boasts a 40 fold improvement in data transfer rate! Don’t waste a microsecond! How Does USB Work With My Systems? Currently, the USB Specification, Revision 2.0, covers three speeds: 480 Mbps, 12 Mbps, and 1.5 Mbps. This means that the DSPEC...

DSP EC jr 2.0 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 overrange, bias on/off state). A single check by the DSPEC jr 2.0 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...

DSP EC jr 2.0 Ballistic Deficit Correction No need to worry about ballistic deficit with the patented digital signal processing of the DSPEC product line from ORTEC. In larger HPGe detectors, a characteristic known as ballistic deficit is sometimes exhibited. This typically results in poor resolution especially for high energy peaks. In analog systems, the ballistic deficit is corrected with either a gated integrator amplifier or through a resolution enhancer module. In digital systems, however, a simple adjustment to the flat top width of the digital filter is all that is necessary. Using...

Display: 240 x 160 pixel backlit LCD provides status information, instrument ID, bias information, live and real time. Concurrent Connections: Limited by the computer and supporting USB hubs. ORTEC CONNECTIONS software supports up to 127 USB connected devices per computer. System Gain Settings: Coarse Gain: 1,2, 4, 8, 16, or 32. Fine Gain: 0.45 to 1. The available range of gain settings supports all types of HPGe detectors. Specifically the following maximum energy values are achievable using the standard ORTEC preamplifier (max gain to min gain): COAX 187 keV to 12 MeV GLP/SLP 16.5 keV to...

Additional DIMS DIM-POSGE DIM-NEGGE DIM-POSNAI DIM-296 Detector High Voltage Supplies Detector Interface Module (DIM): DSPEC jr 2.0 offers high voltage supply flexibility in the form of a microprocessor controlled module, which connects the specific detector to the MCA. On a SMART-1 HPGe detector, the HV module is integral with the detector itself. For "legacy" or "non-SMART-1" detectors, the HV supply is in the form of a Detector Interface Module or "DIM" with 2 m cables. The DIM has a mating connector for the traditional detector cable set: 9-pin D preamp power cable, Analog In, Shutdown...
