Multi-Channel, Programmable Current Source
CS-48-100
The Model CS-48-100 is a multi-channel, programmable current source. Developed for both semiconductor and digital superconductor electronics, it is computer-controlled and features 48 low noise current source outputs. Each source output has the capability to both set and read back currents and can be set to a zero current high Z mute state. Each of the 48 sources are optically coupled for control and are sourced from their own secondary winding for complete galvanic isolation. The device consumes a maximum of only 80 W and handles a maximum load current of 4.8 A total over all outputs. Operating over a range of 0-100 mA on each channel, the device features accuracy of +/-25 ?A. The mute state can be set thru a rear panel interlock or from the front panel button for maximum circuit protection. The unit can be mounted in a standard-sized rack.

Flexible Rope-Type Current Probe
RCT1A and RCT5A
These probes have great bandwidth ensuring accurate measurement even with harmonically distorted wave shapes. For all RCT1A/RCT models, a NIST, NAVLAP, NPL (UKAS) factory traceable calibration certificate and certificate of conformance is supplied. UL/CSA approved materials are used throughout. Three phase and single phase flexible AC current sensors (rope sensors) are available for fast installation in confined spaces, eliminating the need for Electrical Supply Shutdown. Available outputs are 1A @ 2.5VA and 5A @ 0.5VA, this means long cable lengths from current sensor to signal conditioner allow these low VA ratings to be used, even when feeder cable to energy meter distances are large (up to 98 feet / 30 meters)

Digital Current Integrator
The ORTEC Model 439 Digital Current Integrator was designed to accurately measure DC currents or the average value of pulse currents such as produced by accelerator beams. It digitizes the input current by producing an output pulse for specific values of input charge. A front-panel switch permit the selection of three different amounts of charge (10–10, 10–8 or 10–6 coulomb) required to produce an output pulse. The instrument has a digitizing rate from 0 to 10 kHz to provide wide dynamic range on each setting and high-resolution readout without meter interpolation.

Preamplifiers
The primary function of a preamplifier is to extract the signal from the detector without significantly degrading the intrinsic signal-to noise ratio. Three basic types of preamplifiers are available: the current-sensitive preamplifier, the parasitic-capacitance preamplifier, and the charge-sensitive preamplifier. ORTEC manufactures a preamplifier to fit your detector, your application, and your budget.
