all-new fully, quantitative Windows™-based
URSA-II software package has been designed for ease of use in a
32-bit Windows™ environment.
Software includes "MCAce-II" software to run the URSA-II using a
Pocket PC (Jornada, iPAQ, etc.) running WindowsCE. Can be installed
on as many computers as you like, with no restrictions and includes
• 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
• 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.

Minimum System Requirements:
486 computer running Windows 95® or higher. Connects to controlling
computer using a standard RS232 serial port, or USB using
RS232-to-USB adapter. Supports both high and normal data rates using
USB, although, not all computers may be capable of handling the
4096-channels, can also be configured for 256, 512, 1024, or 2048
channels. Internal bias voltage supply provides positive high
voltage from 0 to 2000V at up to 0.5mA. Adjustable shaping time,
0.25 to 10 µs. Wide gain range by utilizing coarse and fine gain
controls, achieve gain from x1 to x250.
Two detector inputs. One standard series "C" connector for detectors
where the signal is joined with the high voltage supply. The other
is 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
External connector provides +5V, +12V, and -12V for external
preamplifiers and two logic signals for notifying external devices
of alarm conditions.
Power On/Off, and Fast/Normal charging rates. (Internal switch
located in the battery compartment suppresses battery-charging
circuitry for when non-rechargeable batteries are being used.)
On/Off, External power availability, and fast charge activation
External 12VDC power supply, six "AA" NiMH rechargeable batteries
(included) with recharging internally, or six standard alkaline "AA"
External 12VDC power jack allows instrument to plug into vehicle.
"Fast Charge" of NiMH batteries can also be selected.
157 x 90 x 44 mm (6.186 x 3.558 x 1.718 in.)
391 grams (13.8 oz.) without batteries.
