Oscilloscopes
Devices that convert electrical power to mechanical power run the industrial world, including pumps, compressors, motors, conveyors, robots and more. Voltage signals that control these electro-mechanical devices are a critical but unseen force. So how do you capture and see that unseen force?
Oscilloscopes (or scopes) test and display voltage signals as waveforms, visual representations of the variation of voltage over time. The signals are plotted on a graph, which shows how the signal changes. The vertical (Y) access represents the voltage measurement and the horizontal (X) axis represents time.
The graph on an oscilloscope can reveal important information:
Voltage and current signals when operating as intended.
Signal anomalies.
Calculated frequency of an oscillating signal and any variations in frequency.
Whether a signal includes noise and changes to the noise.
Most of today’s oscilloscopes are digital, which enables more detailed accurate signal measurements and fast calculations, data storage capabilities and automated analysis. Handheld digital oscilloscopes such as the Fluke ScopeMeter® Test Tools offer several advantages over benchtop models: They are battery operated, use electrically isolated floating inputs and also offer the advantage of embedded features that make oscilloscope usage easier and more accessible to a variety of workers.

Power Supplies
A power supply is a component that supplies power to at least one electric load. Typically, it converts one type of electrical power to another, but it may also convert a different form of energy – such as solar, mechanical, or chemical - into electrical energy.
A power supply provides components with electric power. The term usually pertains to devices integrated within the component being powered. For example, computer power supplies convert AC current to DC current and are generally located at the rear of the computer case, along with at least one fan.
A power supply is also known as a power supply unit, power brick or power adapter.
Function Generators
Function generators are items of test equipment that are able to generate a variety of simple repetitive waveforms. Straightforward signal generators such as RF signal generators or simple audio oscillators focus on producing a good sine waves, but in many cases other waveforms are needed. In addition to producing sine waves, function generators may typically produce other repetitive waveforms including sawtooth and triangular waveforms, square waves, and pulses. Another feature included on many function generators is the ability to add a DC offset. Often some of the low end function generators may only operate up to frequencies of possibly around 100 kHz as the various shaped waveforms are normally only needed at lower frequencies. However many other more comprehensive function generators are able to operate at much higher frequencies, often up to 10 or 20 MHz.
Frequency counters
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 to measure the frequency of repetitive signals, and also for measuring the time between edges on digital signals. Whilst the actual requirements and applications for RF frequency counters and timers are different, they use the same basic circuitry, with some simple internal reconfiguration and as a result sometimes RF frequency counters are also able to act as timers. Typically the very high RF frequency counters will not incorporate the timer capability.
