Visual Editor for the Automatic Test Markup Language (ATML)
ATML Pad
-
Reston Software offers ATML Pad, a visual editor for the Automatic Test Markup Language (ATML).The ATML formats are versatile but complex. Direct editing in XML is next to impossible, even with capable XML editors. ATML Pad overcomes this problem by exposing an application-specific visual interface. ATML Pad manages the complexity of the ATML formats, allowing you to focus on describing your tests. It abstracts XML ID references, allowing you to simply select the referenced item from a list. In addition, ATML Pad can generate XML IDs automatically and ensures that IDs remain unique while you edit the data.ATML Pad allows you to quickly generate complex ATML constructs through a single mouse click. It validates your data during input and on-demand, ensuring that valid ATML documents are produced.ATML Pad interoperates with the NI TestStand ATML Toolkit to deliver automatic code generation solutions that reduce the cost of implementing NI TestStand test programs and ensures their cost-effective long-term maintainability.

COM Express® Type 2 Reference Carrier Board in ATX Form Factor
Express-BASE
Computer on Module
The COM Express approach of custom carrier combined with off the shelf system cores is an excellent solution when you need to customize but lack the time or quantity for a complete redesign. It fits most system integration projects with production volumes from 500 to 10,000 pcs per year. The COM Express concept has a great many advantages over full custom designs, it reduces engineering complexity, lowers the threshold for total project quantity and last but not least brings your product to the market in no time. The average time to design a carrier board is less than half the time of a full custom OEM board.

Thermocouple Vacuum Gauge Tubes
DV-6 Series for Medium Vacuum
-
Teledyne Hastings, manufacturer of the original DV-4, DV-5, and DV-6 thermocouple vacuum gauge tubes, produces vacuum measurement equipment with exceptional stability, accuracy, and reliability under the most demanding conditions.The Teledyne Hastings’ DV-6 series thermocouple vacuum gauge tube acts as a localized sensor which is then paired with a selection of meters or controllers to provide reliable, cost-effective measurements in diverse applications. The robust sensor gauge tube is easily installed into vacuum systems and when properly excited, generates a thermoelectric voltage to provide a vacuum pressure measurement based on gas density. The DV-6 thermocouple vacuum gauge tube fully compensates for temperature and rate of temperature change.Thermocouple gauge tubes are calibrated on vacuum systems that contain N2 or Air, but can be used with other gases. Additionally, thermocouple gauges and their controllers can be recalibrated when a replacement thermocouple gauge tube is installed, following instructions in the manual. However, our DB-20 reference tube is available to confirm meter/controller performance. A complete line of installation accessories are also available to simplify the integration of our thermocouple gauge tubes into a variety of vacuum systems. Our goal is to provide “one less thing to worry about”, when performance matters! With a wide range of meter, fitting, relay and output options, the DV-6 series provides a reliable pressure measurement in numerous industries and applications.
