1×6 Video Distribution Amplifier
VDA206 S-Video
-
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%.

PCI-8511, 2-Port, Low‑Speed/Fault-Tolerant CAN Interface Device
780682-02
CAN Interface
The PCI‑8511 is a fault-tolerant controller area network (CAN) interface for developing applications with the NI‑XNET driver. The PCI‑8511 excels in applications requiring real-time, high-speed manipulation of hundreds of CAN frames and signals such as hardware‑in‑the‑loop simulation, rapid control prototyping, bus monitoring, automation control, and more. The NI‑XNET device‑driven DMA engine enables the onboard processor to move CAN frames and signals between the interface and the user program without CPU interrupts, minimizing message latency and freeing host processor time for processing complex models and applications.

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.

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.

voltage controlled crystal oscillator
VCXO
-
A VCXO (Voltage Controlled Crystal Oscillator) is a crystal oscillator the output frequency of which is controlled by adding an external control voltage via a frequency control input on a variable capacitance component such as a varactor diode connected in parallel to a load capacitance (CL). Epson VCXOs are divided into two types according to Voltage-Frequency (V-F) characteristic slopes depending on the AFC (Automatic Frequency Control) input configuration of the VCXO. One is a VCXO with a positive V-F slope and the other is a VCXO with a negative V-F slope. Please note that the input voltage of a control circuit will vary according to the individual type, as shown in Figs. 3 and 4. Epson's VCXOs are capable of either, depending on the customer's preference. Epson's VCXOs have been increasingly used for broader applications such as slave oscillators in phased-lock loops, or frequency modulators. Among the above types, a VCXO combined with a TCXO is called a VC-TCXO , respectively. These components have the merit of delicately controlling their output frequency electrically.
