1Summary
The Model 970, with a full-featured MCA program, can be used with practically any radiation detector and can extract any data your detector can supply. It has been designed taking into account comments and requests from our current customers. The all-new fully quantitative Windows based software package has been designed for ease of use in a 32-bit Windows environment.
Software also includes 970 for PPC to run the Model 970 using a Windows Mobile Device (Jornada, iPAQ, TDS Recon, etc.) running WindowsCE or Windows Mobile. The Software can be installed on as many computers as you like with no restrictions, and it includes free software updates.
2Software Includes
- Fully editable standard libraries include all 387 isotopes listed in "Kocher's Radioactive Decay Tables."
- Multi-channel scaling mode, peak search and identify, quantification based on ROIs library, or peaks search.
- 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 reanalysis 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 a spreadsheet program. All reports can be previewed, printed, or saved as text or rich text files.
3Inputs & Connectors
The Model 970 provides 4096 channels, and can also be configured for 256, 512, 1024, or 2048 channels. Wide gain range is achieved by utilizing coarse and fine gain controls, for gain from x1 to x250. Shaping time is adjustable from 0.25 to 10 µs.
Probe Connectors
Two detector inputs are provided. One standard series "C" connector is 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 negative, positive, or pre-shaped (positive) signal.
High Voltage Supply
The internal bias voltage supply provides positive high voltage from 0 to 2000 V at up to 0.5 mA. Negative High Voltage is available upon request.
External Connector
The external connector provides +5 V, +12 V, and -12 V for external preamplifiers and two logic signals for notifying external devices of alarm conditions.

6Power & Physical
Power Requirements
The Model 970 runs from an external 12VDC power supply, six "AA" NiMH rechargeable batteries (included) when recharging internally, or six standard alkaline "AA" batteries. The external 12VDC power jack allows the instrument to plug into a vehicle. "Fast Charge" of NiMH batteries can also be selected. The Model 970 is fully portable with four hours of battery life and PPC Compatibility.
