Calibration Specialists provides a time calibration service for stopwatches and timers.

Proper calibration of today’s sophisticated timing test and measurement equipment is essential for preserving measurement accuracy, complying with international standards and sustaining your competitive advantage.

Frequency calibrations measure the performance of frequency standards. The frequency standard being calibrated is called the unit under test (UUT). In most cases, the UUT is a quartz, rubidium, or cesium oscillator. In order to perform the calibration, the UUT must be compared to a standard or reference.

A spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. The primary use is to measure the power of the spectrum of known and unknown signals. The input signal that most common spectrum analyzers measure is electrical; however, spectral compositions of other signals, such as acoustic pressure waves and optical light waves, can be considered through the use of an appropriate transducer. Spectrum analyzers for other types of signals also exist, such as optical spectrum analyzers which use direct optical techniques such as a monochromator to make measurements.

A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine.[1] The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common.

The word comes from Greek τάχος (táchos “speed”) and μέτρον (métron “measure”). Essentially the words tachometer and speedometer have identical meaning: a device that measures speed. It is by arbitrary convention that in the automotive world one is used for engine and the other for vehicle speed. In formal engineering nomenclature, more precise terms are used to distinguish the two.

Frequency counters are test instruments used in many applications associated with radio frequency engineering to measure the frequency of signals very accurately.

These frequency counters and counter timers are widely used within a variety of areas of electronics test to measure the frequency of repetitive signals, and also for measuring the time between edges on digital signals.

An oscilloscope, previously called an oscillograph, and informally known as a scope or o-scope, CRO (for cathode-ray oscilloscope), or DSO (for the more modern digital storage oscilloscope), is a type of electronic test instrument that graphically displays varying signal voltages, usually as a calibrated two-dimensional plot of one or more signals as a function of time. The displayed waveform can then be analyzed for properties such as amplitude, frequency, rise time, time interval, distortion, and others. Originally, calculation of these values required manually measuring the waveform against the scales built into the screen of the instrument. Modern digital instruments may calculate and display these properties directly.
