The goal of most sales pitches is to convince a customer to buy a particular product. 
A seasoned salesperson will tell them why they should buy it and how it will benefit them. As a sweetener, they may even try to entice the customer with a reduced price tag. 
But in some situations, getting something at a fraction of the cost doesn't mean you are necessarily getting the best product. For example, a high-end sports car will cost significantly more than a family sedan, but the sports car will offer a much better driving experience.
The same is true about Keysight's most expensive oscilloscopes. Yes, they come with a higher price tag, but you will get some of the best technology and performance on the market. 
Let's take a look at Keysight's eight most expensive oscilloscopes. We will look at their features and see why these "sports cars" of the oscilloscope world are worth every penny.

A digital storage oscilloscope is an instrument that allows you to visualize electrical waveforms. You use oscilloscopes for various applications, from engineering new products to scientific research.
To read precise waveforms, digital scopes use very high-speed digital circuits. These digital circuits allow the oscilloscope to take quick and accurate measurements. 
The speed and accuracy of these digital circuits come at a cost, which is why oscilloscopes are generally more expensive than other types of test equipment.
Note other factors that contribute to the high cost of some oscilloscopes.

While the above factors contribute to the high price tag of some oscilloscopes, a great solution to get your hands on a high-end oscilloscope at a much lower price is to buy a Keysight premium used oscilloscope. 
Did you know Keysight offers a wide range of high-quality, premium, refurbished oscilloscopes backed by a 1-year warranty? That means when you buy with Keysight, you can rest easy knowing you are getting a quality product backed by a trusted manufacturer.

Bandwidth is one of the most important factors when buying an oscilloscope. 
A scope's bandwidth determines the frequency range at which it can display a signal accurately. 
Bandwidth becomes more important at higher frequencies. Otherwise, you will only be able to see some signal components, and the high-frequency noise is aliased (moved to a lower frequency).
A scope with a large bandwidth will be more expensive than one with a smaller bandwidth, but it will also be better able to capture delicate signals and provide more precise measurements.
A 20 Mhz bandwidth scope would be considered lower-end, while a top-of-the-line oscilloscope has bandwidths reaching up to 100 GHz.

The sampling rate is the number of times per second that a digital oscilloscope takes a measurement (or sample). 
The Nyquist–Shannon sampling theorem states that a signal can be perfectly reconstructed from an infinite series of samples taken at a rate greater than twice the signal's bandwidth.
In a simplified form, this means that the sampling rate must be at least two times greater than the highest frequency component in the measured signal. Most signals of interest require a sample rate in the megahertz (MHz) range. 
As you can imagine, taking millions of samples per second requires significant processing power, translating into a higher price tag for oscilloscopes with high sample rates.

Oscilloscopes are generally available with 1, 2, 4, or 8 channels. 
The number of channels on an oscilloscope refers to the number of input signals that the scope can measure at the same time. So if you are working with a 4-channel scope, you can simultaneously measure up to 4 different signals.
While a single-channel oscilloscope will be enough for many applications, having multiple channels can be extremely helpful (and even necessary) in certain situations. 
For example, if you are measuring the performance of a system with multiple components, it can be very helpful to see all of the signals on one screen. This allows you to identify any anomalies and diagnose problems quickly.
Of course, more channels also mean a higher price tag. A 4-channel oscilloscope will cost more than a 2-channel scope, and an 8-channel scope will cost even more.

Memory depth is the amount of data an oscilloscope can store and display. 
The deeper the memory, the more information the scope will show you. This is important because it affects the sample rate or the amount of information you can see and analyze at a time. 
A scope with shallow memory might only be able to store a few seconds' worth of data, which will not be enough to see signal anomalies over some time. But a scope with deep memory can keep hours' or even days' worth of data, letting you zoom in for a high-resolution view of whatever portion you are interested in viewing.​​ 
This is important for applications like power analysis, where you might need to see an entire day's worth of data to identify trends and optimize performance.
The deeper the memory, the more expensive the scope will be. But for many applications, deeper memory is worth the extra cost.

Now that we have looked at why premium oscilloscopes are so expensive, let's look at 8 of our most expensive Keysight oscilloscopes and see what sets them apart. We will look at things like
