Innovation That Matters
RF Components: Gold Standard Calibration

Gold Standard Calibration

Mercury Systems features a state of the art calibration laboratory to calibrate Mercury Systems brand noise sources as well as sources from other manufacturers.

1.0 calibration data
Merging integrated sub-assemblies with software making it simpler to incorporate noise figure measurement functionality into your system.

1.1 Excess Noise Ratio (ENR). This is the primary calibration data required. ENR is typically calibrated at spot frequency values however Mercury Systems also offers swept ENR data from 10 MHz - 26.5 GHz.

1.2 Complex Reflection Coefficients: Mercury Systems offers its Gamma Calibration Service for Vector Error Corrected noise and noise figure measurements. Phase and magnitude data are given at spot frequencies.

1.3 Temperature characterization: Mercury Systems offers both ENR and Gamma calibration services at customer specified temperature points from -40 degC to +80 degC.

2.0 data format
2.1 Mercury Systems offers calibration data in several formats

2.1.1 Calibration label: For standard noise sources for benchtop noise figure meters, such as the Mercury Systems NS-346 series sources, Mercury Systems prints the data on labels which are affixed to the noise sources via adhesive backed label.

2.1.2 Soft Format: Mercury Systems offers calibration data in several text file and .csv formats as well as in MS Excel spreadsheet upon request. Mercury Systems saves all data from calibration services on its servers at the calibration lab as a back up if the customer loses the data file.

3.0 calibration standards
3.1 Mercury Systems' calibration services are traceable to the National Institute of Standards and Technology. (NIST)

3.2 ENR calibration tractability.:

3.2.1 Mercury Systems Silver Standard ENR Calibration Service (Typical): ENR calibration service calibrates noise sources using a transfer standard (Silver Standard) noise source as a reference. The transfer standard noise source is calibrated at Mercury Systems using a "Gold Standard" noise source as a reference source. The Gold standard noise source is calibrated directly by NIST.

3.2.2 Mercury Systems Gold Standard ENR Calibration Service (Optional): Noise Sources are calibrated directly with the NIST calibrated gold standard as opposed to the transfer standard.

3.2.3 Transfer Uncertainty: Mercury Systems calibration instrumentation adds between 0.05 and 0.15 dB uncertainty from the reference source. The uncertainty is dependant on frequency, ENR of the calibration unit and the VSWR of the calibration unit.

4.0 calibration laboratory
4.1 Environment. Mercury Systems' noise source calibration lab is temperature controlled. ENR measurements are made in an EMI shielded screen room

4.2. Mercury Systems certifies that it maintains up to date proper calibration for all test instrumentation used in its calibration service.

calibration to your requirements
Mercury Systems calibrates noise sources in many different configurations including coaxial, waveguide over frequencies from 10 MHz - 110 GHz. Mercury Systems performs special calibration services depending on your needs. For a quote call Mercury Systems 603-883-2900 x132 or by e-mail
