A test probe, test prod, scope probe or test lead is a physical device used to connect electronic test equipment to a device under test or DUT. They range from very simple, rugged devices to complex probes that are sophisticated, expensive, and fragile. A current probe generates a voltage proportional to a current in the circuit being measured; as the proportionality constant is known, instruments that respond to voltage can be calibrated to indicate current. Current probes can be used both by measuring instruments and oscilloscopes. To measure or display the modulating waveform of a modulated high-frequency signal, for example: an amplitude-modulated radio signal-a probe fitted with a simple diode de-modulator can be used. The probe will output the modulating waveform without the high-frequency carrier.

In-circuit test or ICT is an example of white box testing where an electrical probe tests a populated printed circuit board "PCB", checking for shorts, opens, resistance, capacitance, and other basic quantities which will show whether the assembly was correctly fabricated. It may be performed with a bed of nails type test fixture and specialist test equipment, or with a fixture-less in-circuit test setup.

A function generator is usually a piece of electronic test equipment or software used to generate different types of electrical wave forms over a wide range of frequencies. Some of the most common wave forms produced by the function generator are the sine, square, triangular and saw-tooth shapes. These wave forms can be either repetitive or single-shot which requires an internal or external trigger source. Integrated circuits used to generate wave forms may also be described as function generator ICs. Although function generators cover both audio and RF frequencies, they are usually not suitable for applications that need low distortion or stable frequency signals. When those traits are required, other signal generators would be more appropriate. Some function generators can be phase-locked to an external signal source which may be a frequency reference or another function generator. Function generators are used in the development, test and repair of electronic equipment. For example, they may be used as a signal source to test amplifiers or to introduce an error signal into a control loop.

When acquiring online, kindly make certain you understand exactly what the merchant's return policy is. It's much better to learn ahead of time, instead of purchase and face issues later on. Try to find a location labelled Frequently Asked Question, Returns, or Client service and check out the small print. If you can not discover anything on the topic, you need to e-mail client service. In case you succeed with the bidding in an auction internet site, it is encouraged to call the vendor straightaway. Even if auction sites usually permit a couple of days for your exchange to carry out, calling the vendor the instant you succeed with the bidding can help you pinpoint when you ought to expect the package. When you are shopping online, do shop at home. Never make purchases on the internet using a public Wi-Fi connection due to the fact that online hackers can tap into Wi-Fi connections at hot spots, such as airports, hotels and coffee shops, to get your private information. If you're receiving communications claiming to be from your bank, an online store, a social network, or any other company, the email should be sent from an email extension registered to that company. Banks do not correspond with their customers from email addresses provided by gmail.com, yahoo.co.uk etc.-- it's safer to avoid sending personal details via email at all if you can avoid it.
