Extinction Ratio (ER) Calibrated White Paper

From Tektronix, Inc.

This white paper explains some of the benefits of highly accurate ER measurements in both 10 GbE (Ethernet), with its relatively low ER requirement, and in SONET/ SDH , and the methodology that supports consistent, accurate ER result.

Pulse Generators
Pulse generators are electrical test equipment used to generate pulses that are injected into devices under test in order to study the behavior of these devices.
Digital Multimeters
Digital multimeters (or multi-meters) are used to measure electrical quantities such as voltage, current, resistance, frequency, temperature, capacitance, and time period measurements.
Frequency Meters
Frequency meters are instruments that provide analog outputs as frequencies that vary as a function of the applied input. They display values on a dial, usually with a needle or moving pointer.
Digital Ammeters
Digital ammeters are instruments that measure current flow in amperes and display current levels on a digital display. These devices provide information about current draw and current continuity in order to help users troubleshoot erratic loads and trends
Digital Resistance Meters
Digital resistance meters are instruments that measure electrical resistance. They use solid-state components and display values digitally.
