Specialized Research Instruments for pulse, signal, light and function generators. Berkeley Nucleonics Corp – BNC is a leading manufacturer of precision electronic instrumentation for test, measurement and nuclear research.
Precision Instrumentation – Berkeley Nucleonics
Products include – Pulse and Delay Generators, Arbitrary Waveform Generators and other Measurement Instruments. Handheld Radiation Detection, X-Ray and Gamma-Ray Spectroscopy, Chemical/Bio Analysis.
Model DB-2 Random Pulse Generator – BNC
A random pulse generator that utilizes a charge control concept. Controlled voltage transitions at average rates from 10 Hz to 1 MHz.
Besides random pulse, the Model DB-2 also provides mono energetic repetitive pulses. In this mode, the DB-2 is an excellent general purpose pulser. When the EXT REF input is used with an external ramp, the DB-2 provides sliding pulses to quickly check system or component linearity.

Lake Shore Cryotronics, Inc. is an international leader in developing innovative measurement and control solutions. Their products include sensors for cryogenic temperature and magnetic measurements as well as systems for the magnetic and electronic characterization of materials.
Lake Shore Cryotronics – Measurement and Control Technologies
The Model 372 provides the best possible temperature measurement and control capabilities for dilution refrigerators (DRs) that are intended to be operated below 100 mK. The Model 372 makes it easy to perform multiple tasks that were once very difficult to perform reliably at ultra-low temperatures:
Model 372 AC Resistance Bridge/Temperature Controller
Measure a wide range of resistive devices – With up to 22 different current (I) excitation levels available, the Model 372 is able to perform accurate impedance measurements from several microohms (10-6 Ω) to many megohms (106 Ω), all while keeping power dissipation levels to an absolute minimum.
