Low Phase Noise Amplifiers
Low Phase Noise amplifiers are critical for many applications requiring high signal integrity. This is especially relevant in instrumentation, defense, and telecommunication applications where low phase noise amplifiers are becoming increasingly important as the oscillators improve. Phase noise is described as the close-in noise to the carrier that can often appear as jitter on a clock signal. Analog Devices offers a large portfolio of low phase noise amplifiers to meet a variety of requirements in the LO network, receiver, as well as in the transmitter. Our portfolio supports a wide range of power levels and frequencies to provide the right solution for the given application.

Single Phase Site Energy Meter Test Instrument Type KP-P1001-A
Bofa Instrument & Equipment Co., Ltd
Single phase site energy meter test instrument type KP-P1001-A (without voltage and current source) is an ideal instrument to test all kind single phase energy meters accuracy below 1.0, especially for meters on site. During tests, the tested meter must be on load condition (that means the tested meter must be working). The instrument tests the errors by comparing energy impulse from the tested meter with energy impulse from the reference meter inside the instrument.

Antenna, Loop Sensor
EM-6873 | 20 Hz – 100 KHz
The EM-6873 Loop Sensor Antenna uses passive circuits to transform magnetic field components between 20 Hz – 100 kHz to an equivalent open circuit two-terminal voltage on the receiving instrument. Use of the conversion Factor Chart, supplied with each antenna, will yield the strength of the magnetic induction field referenced to a uniform field. The loop is electrostatically shielded and therefore is sensitive only to the magnetic component (B-field) of the electromagnetic fields.
