*This is a Web introductory price for one calibration of the NARDA 3003-30. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Noise Density
Noise Density is the amount of noise within a defined bandwidth, usually normalized to 1 Hz.

Spurious Signals
Spurious signals are undesired signals. They can be considered in two classes. They can be stationary; their frequency and amplitude do not change significantly, or non-stationary, where the frequency and/or amplitude change significantly over short time periods.
