Not all amplifiers are created equal, so how can you be certain that an amplifier will work for your needs? You deserve to be confident that the amplifiers used with your test-and measurement lab benches will meet the requirements of your specific applications, are reliable, and are equally well-supported pre-and post-sale. When it comes to application expertise, reliability and support, there is no company that does it better than Maury.

• Ideal for applications requiring high ENR and immunity to large incident RF power
• Low VSWR
• Built-in isolator

The NC3400 Series coaxial AWGN noise sources are an excellent choice for applications requiring high ENR and immunity to large incident RF power, such as ATE, radiometer, and radar systems. The calibration accuracy and flatness of the NC3400 Series noise sources are enhanced by their low VSWR. The built-in isolator provides almost constant output impedance as the noise source bias is switched on and off. The isolator also protects the noise diode from incident RF power (consult the factory for higherpower units).

An SMA female connector is standard for the RF output and a BNC female connector is standard for the bias input. Other connectors are available as options.

• Excellent temperature and voltage stability
• Units for noise figure meters feature 15.5-dB ± 0.75 dB ENR output
• High-output units for radar and satellite communications system testing feature output between 26 and 35 dB ± 1 dB ENR

The NC3000 Series calibrated coaxial AWGN sources are well suited for receiver testing, noise figure measurements, or applications that require broadband noise and fast switching times. Several models include output isolators, and voltage regulators that provide excellent stability over varying temperature and voltage ranges. The NC3000 Series includes the NC3100 units with 15 dB ENR output for noise-figure meters, and the NC3200 Series high-output noise sources with outputs between 26 and 35 dB ENR for radar and satellite communications system testing.

• Speed: Calibration is faster since there is no need to manually connect and disconnect standards.
• Accuracy: Eliminates errors caused by manual handling, such as connector inconsistencies and improper torquing.
• Ease of Use: Minimal user interaction is required, making calibration simpler and more accessible.
• Reliability: Reduces wear and tear on VNA ports and connectors, prolonging their lifespan.
• Consistency: Provides repeatable results across multiple calibration sessions and users.

• Custom electrical testing available upon request
• Wide package variety with custom configurations
• NC100 & 200 series for audio and RF applications
• NC300 & 400 series for microwave application

Noise diodes are the fundamental building blocks for analog noise systems. They are categorized for performance characteristics that enhance their broadband noise output and flat spectral response. All Maury noise diodes can deliver symmetrical white Gaussian noise and flat output power versus frequency*.

* Flatness and output power are dependent upon peripheral circuit characteristics

• Outstanding stability
• Fast switching speed
• Ripple-free response over standard waveguide bands

The NC5000A Series AWGN noise sources feature outstanding stability, switching speed, and ripple-free response over standard waveguide bands. The high stability of the NC5000A Series allows these units to be used in place of cumbersome gas tube noise sources.

Ripple in the output of noise sources has a direct effect on measurement accuracy, so Noisecom has tailored the response of the NC5000A Series so that ripple is minimized throughout the specified frequency range.

A precision fixed termination (or load) consists of an immovable, (fixed) termination which, when mated to the end of a trans-mission line or cable, absorbs nearly all of the signal energy traveling toward it. An ideal “matched” condition exists when a termination with an impedance value of Z0, is connected to the end of a transmission line or cable that also has a characteristic impedance of Z0. Such an ideal “matched” condition (one with no mismatch between the termination and its mated line or cable) is critical if a voltage standing wave ratio (VSWR) of 1.0:1 is to be achieved in a system with a 50 or 75 ohm impedance value. Simply put, the more closely the 1.0:1 ratio is approached, the more accurate the measurements that can be made from a system.
