• Additive white Gaussian noise
• Integrated amplifier
• Manual attenuator
• NC6000A -BER testing, and SNR applications
• NC8000A – Secure signal jamming
• Military Applications
• Custom configurations available (consult factory)

The NC6000A and NC8000A Series instruments are designed for general-purpose noise applications on the bench, or in a rack test station. The manual controls make it simple to operate and reduce test set up time. Standard units can be modified for specific customer requirements. Please consult the factory for pricing and availability of these requests.

• Calibration-grade metrology standards
• Used for VNA calibration and/or calibration validation

Fixed flush and fixed offset short circuit terminations (shorts) are used to establish reference planes in transmission systems and as key elements in the calibration of vector network analyzers (VNAs). Offset shorts can be used for banded calibrations of VNA. Those with the longest offset are often used to evaluate the calibration effectiveness of a VNA by measuring the effective source match after calibration.

• Broadband coverage
• Extremely good temperature stability
• Superior voltage stability
• Noise figure meter-compatible

The NC346 Series is designed for precision noise figure measurement applications. Each module’s low VSWR reduces multiple reflections and significantly increases the measurement accuracy for most noise figure test configurations.

• Use of High Performance RF Resistors
• Choice of Resistor values available
• Choice of body styles, Infinity, ACP or FPC
• Can help to stabilize oscillations in high-gain devices
• Impedance match to low dynamic resistance laser diodes
• Custom configured for your application

• Complete bias circuits
• Requires no external components
• Extremely flat output power versus frequency characteristics

The NC500 (through-hole) and NC500SM (surface mount) Series noise modules are an economical solution for built-in test requirements. They contain complete bias circuits and require no external components. Some models contain additional gain stages for high power ENR output (51 dB). The surface mount package is suitable for mounting on micro strip. The modules have extremely flat output power versus frequency characteristics that are insensitive to temperature and voltage variations.

• High-level noise modules mounted on a circuit board
• Modified BW, output power, and flatness specifications

The NC2000 Series amplified noise modules are an excellent choice for high-level noise modules mounted on a circuit board. The NC2000 Series modules are housed in 24, or14-pin dual-inline packages. The NC4000 series modules are housed in a 40-pin module that cover similar noise bands to the NC2000, but have higher crest factor, and 60 dB of TTL controlled attenuation. Modified BW, output power, and flatness specifications are available for these modules. Please consult Noisecom for availability, and appropriate package style.

• Calibration-grade metrology standards
• Used for VNA calibration and/or calibration validation

Shielded, coaxial opens are used in the calibration of vector network analyzers to provide a nominal 180° phase offset from a compatible reference short over a wide range of frequencies. At these frequencies, open circuit terminations are inherently imperfect. Shielding the open essentially eliminates radiation loss, but creates a residual frequency-sensitive capacitance. An accurate knowledge of the open’s effective capacitance is essential to an accurate calibration of the analyzer. Maury opens are characterized for effective capacitance versus frequency by means of a fourth order polynomial curve fit, and the nominal capacitance coefficients are provided with each unit.

• 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

• Used for VNA calibration and/or calibration validation

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.
