Features
Read full description

InterSpec assists in analyzing spectral nuclear radiation data, using a peak-based methodology. Common uses include identifying nuclides present, determining source activity, shielding amounts, source age, or other nuclear reactions present. InterSpec also provides a number of other tools useful for analyzing radiation data including spectral file format converting, dose rate calculations, interactive nuclide decay and reference information, gamma cross section calculations and references, and more. InterSpec can open data files from most common spectral radiation detectors (e.g., most NaI, HPGe, LaBr, CLYC, CsI, etc. based systems) and assist in their analysis.

Features
Read full description

The Z-COMM SSG series of Smart Phase Locked Loop (PLL) modules provide high performance in a compact package suitable for any number of applications. Fully programmable through a unique Bluetooth interface, or USB cable, the user may adjust functions such as frequency, sweep mode, step time, step size, and power output, among others. LED indicators provide a visual cue of the status of the various functions. Its rugged enclosure lends itself to in-field use as well as bench top testing. The highly reliable output signal, excellent phase noise, and flexibility of an internal reference or input for an external reference, provides RF engineers with an adaptable RF tool.
