• Full-featured library editor. Standard libraries include all 497 isotopes listed in the "Kocher's Radioactive Decay Tables."
• Multi-channel scaling mode, peak search and identify, quantification based on ROIs or peaks search.
• Dual-channel emulator allows use with gas proportional or phoswich detectors as a "gross alpha/beta" counter-scaler.
• Sophisticated multiple alarm functions are based on the overall count rate, individual ROIs, exceeding a specific rate or an increase in rate over a specific time interval. Alarms can trigger external devices.
• Provisions are included for acquiring and saving spectra repeatedly and continuously while unattended. Spectra can be saved and reloaded to "live" for re-analysis or additional data accumulation, or loaded as a background spectrum. Saved spectra can be superimposed on the "active" spectrum for comparison. Spectrum format is easily accessible by your spreadsheet program. All reports can be previewed, printed, or saved as text or rich text files.
• "ASCII" mode allows control of and data collection from the URSA-II with user's own software or hardware.

The URSA-II Radiation Spectrum Analyzer is a full-featured multichannel analyzer that can be used with almost any radiation detector and can extract any data your radiation detector can provide.

Two detector inputs are available with URSA-II. One standard series "C" connector is provided for detectors where the signal is joined with the high voltage supply. The second input is used for detectors having separate connections for high voltage (SHV connector) and signal (BNC connector). Active detector input is selected via software, and can be negative, positive, or pre-shaped (positive) signal.

An external connector provides +5V, +12V, and -12V for external preamplifiers and two logic signals for notifying external devices of alarm conditions.

URSA-II Radiation Spectrum Analyzer is a quantitative Windows™-based software package that has been designed for use in a 32-bit Windows™ environment. The package includes the "URSA-II for PPC" software program which allows you to run the URSA-II using a Pocket PC (Jornada, iPAQ, TDS Recon, etc.) that utilizes WindowsCE. The software can be installed on as many computers as you like, with no restrictions. Free updates are included.

The URSA-II Radiation Spectrum Analyzer has 4096-channels which can be configured for 256, 512, 1024, or 2048 channels. Its Internal bias voltage supply provides positive high voltage from 0 to 2000V at up to 0.5mA and an adjustable shaping time of 0.25 to 10 µs. Wide gain range is achieved by utilization of coarse and fine gain controls.
