URSA II Universal Radiation Gateman
The URSA II has been designed taking into account comments and requests from our current URSA customers. It has a full-featured MCA program that can be used with practically any radiation detector and can extract any data your detector can supply!
Minimum System Requirements:
486 computer running Windows 95TM 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 dataflow.
Specifications:
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.
Detector Connector:
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 (positive) signal.
External Connector:
External connector provides +5V, +12V, and -12V for external preamplifiers and two logic signals for notifying external devices of alarm conditions.
Power:
External 12VDC power supply, six "AA" NiMH rechargeable batteries (included) with recharging internally, or six standard alkaline "AA" batteries.
External 12VDC power jack allows instrument to plug into vehicle. "Fast Charge" of NiMH batteries can also be selected		 Must be used with the RAP scintillation probes. Adjustable alarms, RS232 output, and rechargeable.

Detector Options:
See RAP Scintillation Probes
Ranges:
1 to 15,000 CPS
1 µR/hr to 10 mR/hr
.01 to 100 µSieverts/hr
