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.

PZ2131A
Source Measure Unit
The Keysight PZ2131A is a high-channel density precision source / measure unit (SMU) having 5 channels per module and saving space for a wide range of applications requiring numerous precision power supplies. The narrow-pulse function and fast Digitizer Mode allow the PZ2131A to expand the conventional static DC measurements to emerging dynamic measurements. Its seamless current measurement ranging function eliminates the time it takes to change the range and expands the dynamic range to cover multiple measurement ranges, which reduces test duration. These capabilities make the PZ2131A suitable for applications that require numerous precision power supplies, such as semiconductor reliability tests and integrated circuit (IC) tests. The Keysight PX0107A low noise filter adapter lowers its voltage source noise level, which makes the PZ2131A suitable for noise-sensitive applications such as quantum computing as well.

Broadband Coaxial Noise Sources
-
Our integrated noise modules contain all the required biasing circuitry and only need a positive voltage to activate for an easy installation. Since they typically do not contain amplification, the raw noise output from the diode is seen at the output of the module resulting in a maximum ENR of approximately 35dB. Primary applications include system built-in test and laboratory use.

Full band noise figure and gain test extenders are offered to extend noise and gain measuring capabilities up to higher millimeterwave frequency ranges. These extenders are designed to interface with noise and gain test systems that have an input IF of 10 MHz to 1.6 GHz, such as the industry standard Keysight 8970A/B, N8975A and Maury MT 2075B. The noise figure and gain test extenders include a high-performance, solid-state noise source (STZ series) and a full waveguide down converter (STC series), which consists of a Faraday isolator (STF series), full band mixer (SFB series), frequency multiplier, and IF amplifier. A frequency source with an output signal in the frequency range of 10 to 20 GHz is required as a local oscillator for the down converter. The noise source is automatically powered on and off by the noise figure meter.
