Series Voltage References
-
Analog Devices offers a broad line of series voltage references with low dropout, low power, and excellent line regulation. These devices are voltage references that are functionally similar to a three-terminal regulator. Some series voltage references are designed to also operate in shunt mode by biasing the output pin and leaving the input pin open circuit. Series mode voltage references have the advantage that they draw only load and quiescent current from the input supply.

Bofa Instrument & Equipment Co., Ltd
Three-phase site energy meter test instrument type KP-P3001-A (without voltage and current source) is an ideal instrument to test all kind three-phase energy meters accuracy below 0.2, especially for meters on site. When we want test a meter errors, the tested meter must be on load condition (or we can say the tested meter must be working). The instrument can test the errors, by comparing energy impulse from the tested meter with energy impulse from the reference meter which inside the instrument. The equipment is box structure and weight is very light, easy to carry, it is very convenience to test the installed meters on site.

Spectrum Analysis, Up To 13.5 GHz
S930901B
-
The S930901B spectrum analysis adds high-performance microwave spectrum analysis to the PNA family up to 13.5 GHz. With fast stepped-FFT sweeps resulting from optimized data processing, the SA application provides quick spurious searches over broad frequency ranges. Simultaneous spectrum measurements can be done using up to five test and reference receivers. This multi-channel SA can be used with the internal swept-signal generators for efficient measurements of spurious signals emanating from mixers and frequency converters. The SA application employs source-power and receiver-response calibration as well as fixture de-embedding, providing in-fixture and on-wafer spectrum measurements with the highest level of accuracy.

INSTOCK Wireless Components, Inc
PD5023 is an IP67 outdoor, weather resistant, DC blocking, two way, RF broadband, 50 ohm, power divider, power combiner furnished with N type coaxial connectors. The passive Wilkinson design passes RF and the 10 MHz reference signal through both ports while blocking DC current. This configuration is typically used in combining applications to prevent passing DC to the sum and adjacent ports. Max voltage rating at the DC blocked ports is 50 VDC. All wireless band applications in the frequency range from 698 to 2700 MHz are covered with best in class RF performance. The RoHS compliant PD5023 is a bidirectional device capable of 40 W max microwave input power levels in both power splitter and combiner apps.
