Multiplying Current Output D/A Converters
Analog Devices offers a wide range of high precision, multiplying current output (IOUT) D/A converters (DACs) that feature ±1 LSB INL and DNL specifications, from 12-bit up to an industry-leading 18-bit resolution. Our portfolio includes single and multiple D/A converters in small packages with parallel or serial SPI interfaces. Multiplying current output R-2R D/A converters allow for an external amplifier that’s optimized for specific applications and that does not require reference buffering, which enables high linearity. The SoftSpan™ feature allows software selectable output spans, therefore eliminating the need to add precision gain stages and the associated external jumpers, precision resistors, and amplifier circuitry. Integrated precision resistors allow for reference inversion, bipolar offset, and offset and gain adjustment.

Emissions Test System
PC-114
Perform Radiated & Conducted EMI pre-compliance testing at your facility up to 1 GHz. Com-Power PC-114 EMI emissions test system is a ideal solution performing pre-compliance EMC testing from 9 kHz - 1 GHz.. It has essential equipment needed for radiated and conducted EMI emissions measurements. The system includes a spectrum analyzer, antennas, near field probes, a preamplifier, LISN and a non conductive antenna tripod. Pre-compliance testing in EMC is a commonly used term not easy to define. In general, it implies testing done prior to formal testing for legal compliance. Formal legal compliance is performed at a facility designed and equipped with test instrumentation that is fully compliant with the applicable EMC standards. Such facility and instrumentation is capital intensive and can be expensive even to rent and not easily available. Compliance testing is performed per exacting requirements of the Standards and other reference documents adhering to the test methods and last detail. In addition, the test facility may require to be accredited by an accreditation body such as NVLAP, A2LA. Often it is desirable to know prior to compliance testing at such facility, whether a product is close to compliance and also how close. Pre-compliance testing is specially useful for specifications such as FCC, Part 15, EN 55022 or EN 55011 (CISPR 22 or CISPR11). Pre-compliance testing usually means using the full compliance methods but making a few educated compromises in use of site or equipment to reduce costs and testing time. Here are some benefits of pre-compliance testing.

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.
