THE URSA-II |
URSA-II Hardware Specifications
- 4096 channels. Can also be configured for 256, 512, 1024, or 2048 channels via software.
- Internal bias voltage supply. Provides positive high voltage from 0 to 2000V at up to 0.5mA.
Adjusted via software. Negative high voltage supply available on request.
- Adjustable shaping time, 0.25 to 10 µs. Adjusted via software.
- Wide gain range. By utilizing coarse and fine gain controls, achieve overall gain from less
than x1 up to x250. Adjusted via software.
- Two detector inputs. One is a 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).
-
The active detector input is selected via software, and can be a negative, positive,
or pre-shaped (positive) signal.
-
Powered through external jack by a 12VDC power supply (supplied at no extra cost) or
six "AA" NiMH rechargeable batteries (included). Batteries recharge internally, whether
the URSA-II is operating or not. "Fast Charge" of NiMH batteries can also be selected by
toggling a switch. If desired, six standard alkaline "AA" batteries can be used (but cannot
be recharged--switch inside battery compartment selects battery type). The URSA-II can also be
powered directly through the external jack by 12VDC provided by a vehicle.
-
External connector can provide +5V, +12V, and -12V if needed for external preamplifiers.
-
External connector can provide two logic signals for notifying external devices of alarm conditions.
-
"ASCII" mode provided which allows control of and data collection from the URSA-II with user's own software or hardware.
-
Connects to controlling computer using a standard RS232 serial port. Also supports USB using RS232-to-USB adapter.
-
External controls consist of two switches. One turns the power on and off, and the other switches between fast
and normal charging rates. (An internal switch located in the battery compartment suppresses battery-charging
circuitry for when non-rechargeable batteries are being used.) All other controls are set using software.
-
External indicators consist of three LEDs. One indicates external power availability, one indicates that the
fast charge is activated, and one indicates the URSA-II's on or off state.
-
Small in size. The URSA-II measures 6" long by 3.5" wide by 1.8" tall. Weighs about one pound with batteries installed.
