An oscilloscope is indispensable to anyone working with or repairing electronics, but finding a good quality product at a reasonable price can sometimes be a challenge. This is especially true if you're replacing an older unit; you may not be aware of all the technological advancements made in the industry.

There are multiple types of oscilloscopes on the market, and each one has its own specific purpose. Some are designed for use in the field, while others have very high-tech functions that you may never need. You may come across the following in your research:

1. Handheld oscilloscopes

2. Electric oscilloscopes

3. Analog oscilloscopes

4. Digital oscilloscopes

Look at different digital oscilloscopes to decide which type is best for your business

The first thing you should look at when shopping for a digital oscilloscope is the size of the unit. If you're going to be out in the field a lot, you want to pick a handheld model. If you'll be working in a repair shop or lab, a larger model may do just fine. You'll also want to look at the software that works with the scope, the size of the monitor, and the bandwidth.

I recommend: Find the right oscilloscope for your job. Look at the chart available at Tektronix for a quick overview of the different models available. LeCroy has a similar lineup and lets you go further by configuring your oscilloscope to your specifications for a truly custom fit.

Get a handheld oscilloscope that plugs into a USB port for added functionality

When looking at handheld oscilloscopes, you want something that's easy to use and that can interface with your other computer equipment seamlessly. Many of the newer models plug into a computer's USB port, so you can download data onto your laptop or desktop and start analyzing the information right away.

I recommend: Get a USB-compatible oscilloscope. Crag Technologies offers the PicoScope 3000 series that can run off the power from your laptop via the USB port, which makes it really convenient on the go. Fluke also carries a couple of USB models that are worth a look.

Choose a used industrial oscilloscope that fits your budget

A good oscilloscope can be pricey, so if you're on a tight budget, you might consider buying a used model to save some money. Some companies recondition used systems so that you get a product that's in great working order for a fraction of the price.

I recommend: Buy used and save some money. Both Electro Rent Corporation and Test Equipment Depot specialize in used scopes, which can save you quite a bit over buying new. Look for a product that has at least a 90-day warranty, so you can trust that it's in good working order when you receive it.
