Fast Temperature Shift
CherryTemp
-
CherryTemp is a temperature controller based on two independent Peltier channels, allowing for very accurate temperature control and ultra-fast shifts from 5°C to 45°C. A thermalization liquid circulates from a reservoir to the heat exchangers (heating/cooling Peltier elements) where it is thermalized to a target temperature. Once thermalized, this liquid can be quickly injected to a microfluidic device (CherryTemp chip) mounted near the sample. Because of the small thermal mass (the distance between the microfluidic chip and the sample), the temperature transfer is very fast (less than 10 seconds) and of unprecedented accuracy due to a feedback loop control of the room temperature and the heat-sink played by immersion objective lenses.

PXI Source Measure Unit
Source Measure Unit
PXI Source Measure Units (SMUs) combine high-precision source and measure capability with features designed to reduce test time and increase flexibility. These features include high channel density for building parallel SMU test systems, deterministic hardware sequencing for minimizing software overhead, and high-speed update and sample rates for quickly changing setpoints and acquiring data. Additionally, the flexible sampling rate and streaming capability of PXI SMUs allows you to use the instrument as a digitizer to capture transient behavior, and the digital control loop gives you the ability to adjust the transient response of the instrument. The ability to change the transient behavior of the SMU, called SourceAdapt, reduces SMU settling time and minimizes overshoot and oscillations, even with highly capacitive loads.

20 GHz Signal Source
VCO Series
-
The SC5510A and SC5511A are VCO-based, synthesized signal sources with very low phase noise and an amplitude control of 0.01 dB throughout its -30 dBm to +15 dBm output power range. By utilizing a unique multiple phase-locked loop architecture, phase spurs are kept below -70 dBc across the entire tuning range, even at 1 Hz step resolution. Download the data sheet to see how the impressive features and specifications of these modules make them stand out when compared to other small modular synthesizers. These 20 GHz signal sources include an additional, independent RF2 channel with a tunable frequency range from 100 MHz to 3 GHz and a tuning resolution of 25 MHz. The extra channel makes the modules suitable for either single-stage RF conversion systems or dual-stage image suppression up/down converter systems. Both modules make great general-purpose laboratory signal sources where demanding low phase noise and signal purity are required. They are both ideal choices as an integrated clock source for fast DAC and ADC applications, especially those that require variable sampling rates. Full implementation instructions, GUI, driver software, and example code are provided with each module.

Contact Resistance Tester
-
Weshine Electric Manufacturing Co., Ltd
The loop resistance tester is used to test the conductive loop resistance of various switchgear, and the test current shall not be less than 100A. Due to the oxidation of the contact surface, poor contact tightening and other reasons, the contact resistance increases. When a large current flows, the temperature of the contact point increases, which further accelerates the oxidation of the contact surface and further increases the contact resistance.

RGB 1×3 Video Distribution Amplifier
VDA403
-
Video Distribution Amplifiers (sometimes called a video splitter – not to be confused with a video split screen controller such as our PXD510E split screen controller) are typically used for connecting a camera or other video source to several monitors that do not have “looping” inputs. In this situation, each monitor has a permanent 75 ohm termination. With two non-looping monitors connected together, the line would be double loaded and result in a dim picture on each monitor. Using a Video Distribution Amplifier will solve this problem by driving each monitor individually at 100%.The second application is when the video signal is run over distances greater than 50 feet. The coaxial cable has a fair amount of signal loss over long distances. When multiple monitors are connected after long runs of coax, the degradation can be severe, especially when dealing with modern, high bandwidth signals that have 500+ lines of resolution.The VDA403 is a Video Distribution Amplifier designed for professional applications. It will operate with NTSC & PAL video signals as well as many common Black & White signals. These units use the latest integrated amplifier technology for superior performance and reliability. Custom units or modifications can be manufactured at a reasonable cost.

Fully Differential Amplifiers
-
Differential amplifiers allow the process of single-ended input to complementary differential outputs or differential inputs to differential outputs. These amplifiers feature two separate feedback loops to control the differential and common-mode output voltages. Analog Devices fully differential amplifiers are configured with a VOCM pin, which can be easily adjusted for setting output common-mode voltage. This provides a convenient solution when interfacing with analog-to-digital converters (ADCs). ADI also offers a series of differential receiver products that convert differential input signals to single ended output.
