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.

Materials Test Systems
-
An impedance analyzer is a device that uses a programmable AC voltage / current source, together with voltage and current measurement circuits, to characterize sample impedance over a wide range of frequency. An example of this being the world famous Solartron Analytical 1260A Impedance Analyzer that provides EIS impedance characterization over more than 12 decades of frequency from uHz to tens of MHz. Impedance Analysis characterization is a key technology that enables new materials development for semiconductors, smart-materials, ferroelectrics, piezo-electrics, solid oxide, solid electrolytes, ceramics, polymers, OLED and many more materials.

Noise Source, 10 MHz to 18 GHz, nominal ENR 6 dB
346A
Noise Source
The Keysight 346A noise source is the ideal companion to Keysight's noise figure solutions. Since it is broadband (10 MHz to 18 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source reduces a major source of measurement uncertainty; reflections of test signals. The very small change in reflection coefficient (<0.01) from ON to OFF is designed especially for accurate characterization of input-impedance-sensitive devices (like GaAsFETs and many UHF amplifiers).
