Many people who wish to start a business in testing believe they need a room's worth of equipment to get started. The truth is that you don't need much more than the minimum necessities to get by. Before starting a business, you should have a degree in electronics and complete a testing and tagging course.
a pulser for logic
The most fundamental testing tool you'll require is this one because it aids in diagnosing digital circuit issues. The pulse's primary function is timing input and output pulses, which enables you to gauge a pulse's impact on a circuit. Sometimes the pulse can also activate a circuit that might not have been working properly before. When utilized properly, pulses can aid in identifying problems with digital circuitry and potential remedies.
Temporary counters
They assist in measuring each signal's frequency. The proper operation of a circuit can be confirmed by frequency counters. For instance, it is possible to confirm whether infrared transmitters that claim to send a 40KHz signal are indeed doing so. If this is confirmed, a sticker can be applied to the device appropriately. Modern frequency counters can often be used for a variety of digital and analog circuits requiring 0 to 12 volts. Use a counter with a prescaler feature, which is best used to test computing equipment, if you want it to be able to detect very high limits.
One that sweeps
With a small difference, this functions quite similarly to a function generator. The device has a wide range of signal-producing capabilities that go beyond those of a typical generator. This makes it possible for it to sweep for signals from the bottom up. Yet this device can also detect frequency problems in a variety of circuit types. This implies that the device will detect and alert you if a circuit turns out to be sensitive to a specific frequency. This is highly helpful for testing sensitive electronic devices that can malfunction even from the smallest amount of outside interference.
Inertia meter
Someone with a degree in electronics will tell you that appliances can develop all kinds of issues due to static electricity. Even the smallest amount of static electricity can fry chips and destroy circuits. A static meter can be used to check whether a device can withstand a certain amount of static electricity. The kind and use of the appliance will largely determine what needs to be done to make it more static-proof if the reading is discovered to be excessively high.
Experience and expertise with the aforementioned equipment are prerequisites for working in the testing industry. That being said, your return on investment is rather quick once you get the feel of things and invest in the best tools.
