The VectorStar ME7838 Series broadband VNA offers the widest available single frequency sweep from 70 kHz to 110, (ME7838AX to 125), (ME7838EX to 125), to 145 GHz, and to 220 GHz with mmWave bands to 1.1 THz. 

• The ME7838AX or ME7838EX version can easily be upgraded to 145 GHz and to 220 GHz
• All versions may be configured to include banded millimeter-wave modules up to 1.1 THz
• Industry-best calibration and measurement stability: 0.1 dB vs 0.6 dB over 24 hrs.
• All versions support the 3744x-Rx receiver for noise figure measurements, including the ability to characterize differential noise figure, to 125 GHz
• Compact, lightweight mmWave modules (0.6 lb vs 7+ lbs and 1/50 the volume) offer low cost installation on smaller probe stations.

• Directly compatible with most commercial VNA’s
• Available as polynomial and characterized device kits
• Measure S-Parameters with uncertainty when used in conjunction with Maury’s Insight software platform

Maury offers coaxial and waveguide VNA calibration kits.

Coaxial calibration kits are offered in Polynomial SOLT, Characterized Device (CD) SOLT, and TRL, depending on the connector series. Where available, CD kits improve calibration accuracy when compared to SOLT kits based on polynomial definitions as each calibration kit is provided with individually characterized short, open and fixed load standards, whose S-parameters can be loaded into commercial VNAs directly or when used with Maury’s Insight™ software platform. When combined with Insight™, users will be able to quantify the uncertainty contribution of their calibration kit to their overall measurements. CD cal kits result in TRL-like accuracy with fixed-load SOLT ease-of-use.

• 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.

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

Maury mismatch airlines have been designed as verification standards to be used in VNA calibration validation. Each mismatch airline is provided with factory S-parameters data that can be compared with user-measured S-parameters for VNA calibration validation. Measurement uncertainty is also provided, and uncertainty boundaries can be used for definitive calibration validation when used in conjunction with MT940B Insight Real-Time Uncertainty Add-On.

• 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.

Junkosha’s new mmWave VNA Test Cable Assembly exhibits excellent phase (within +/- 4.5˚ at 50 GHz), and amplitude (within +/- 0.08 dB at 50 GHz) stability in flexure alongside strong phase stability in temperature through its 50 GHz bandwidth, available with NMD connector.

The assembly also displays impressive performance durability, surpassing 40,000 tick tock cycles during testing. The cable is bent 180˚ on a 2.25” radius mandrel with ease, demonstrating superior flexibility and no spring back. A ruggedized port side NMD connector is also available to ensure reliable connections to the VNA.
