The only issue that we can see with the unit is the 1 GHz Spectrum Analyzer. This is simply an FFT channel that does not have a good noise floor or problematic transient response.
What to Look For in an Oscilloscope?
Before going through our comparison list, it is a good idea to now the different criteria to consider when picking an oscilloscope. This includes the bandwidth and sample rate speed of each device.
This criterion is the maximum frequency of the signal that goes through the device. It is important to note that the maximum frequency of an oscilloscope should be five times higher than the max frequency of the scope you are looking to measure. While oscilloscopes with high-frequency scopes are expensive, these can provide accurate readings on the frequency range that you want to measure.
• Sampling rate
Almost all digital oscilloscope has two different modes of sampling rates: equivalent-time sampling (ETS) and real-time sampling (RTS). ETS is compatible with repetitive signals or ones that are stable. On the other hand, RTS works with single-shot or changing signals. To make sure that you pick an oscilloscope with the correct sampling rate, check on the manufacturer’s specification for devices you intend to check.
Memory is the amount of capture sample points by the device. This criterion translates to how much of the signal that the oscilloscope can store. A scope’s memory can affect the sampling rate of the device, which is apparent when you zoom in on a signal reading. Essentially, you may want a scope with a high memory capacity to get most out of the device’s sampling rate
• Digital and analog
This is likely not a criterion to use when comparing the different Tektronix Oscilloscope, but we need to state that analog scopes are outdated equipment. These are ideal for old devices or for hobbyists who collect this type of model. If you need an oscilloscope for modern devices or practical usage, digital scopes are the way to go.
An oscilloscope’s resolution affects the accuracy of its signal reading. The most common resolution is 8-bit among many scopes. This gives a common look at digital signals, but it is favorable for looking at analog signals. For analog signals, you will want a resolution of 12 to 16 bit. With a high resolution, you can get an accuracy of one percent, which is better than the accuracy range of around three to five percent that 8-bit resolution can offer.
The number of channels available on an oscilloscope can be useful. By using a mixed-signal scope, you can isolate an activity without using an oscilloscope solution or a combined logic analyzer. In general, most scopes have two or four channels.
You should have a clear idea on the differences of each of the Tektronix Oscilloscope on the market. Before buying one, always consider how you will use a unit for your work or hobby. While scopes with a higher bandwidth may seem ideal, you might only need one with a maximum range of 100 MHz. On the other hand, it pays to invest in high-end scopes if certain features such as 16 digital channels and multiple automated measurements can help you with your work.
