OSCILLOSCOPE SELECTOR GUIDE
Tektronix offers oscilloscopes for many different applications and uses. To help you choose the right scope for
your needs, the most common criteria for selecting a scope are listed below, along with helpful tips for determining
your requirements.
Bandwidth
All oscilloscopes have a low-pass frequency response that rolls
off at higher frequencies. Oscilloscope bandwidth is specified as
being the frequency at which a sinusoidal input signal is
attenuated to 70.7% of the signal’s true amplitude – the -3 dB
point. Your oscilloscope must have sufficient bandwidth to
capture all relevant frequency components of your signal. If you
regularly work with digital signals, it may be easier to consider
bandwidth by comparing signal and oscilloscope
rise time specifications. Use an oscilloscope with a rise time
specification five times faster than your signal rise time to
keep error below 2%.
Rule: Bandwidth > 5 x Highest Signal Frequency

Digital Channels
and Spectrum Analyzer Input
Today’s oscilloscopes offer more than just analog channels
for system-level troubleshooting of complex designs.
• If you need to analyze a parallel bus or multiple serial buses,
the Tektronix MSO Series of mixed signal oscilloscopes and
MDO Series of mixed domain oscilloscopes offer 16 digital
channels and up to 4 analog channels for analyzing multiple
signals at once.
• If you are working with RF signals, the Tektronix MDO Series of
mixed domain oscilloscopes offers a built-in spectrum analyzer
for time-correlated analysis of analog, digital and RF signals.
1
Sample Rate
The faster an oscilloscope samples, the greater the resolution
and detail of the displayed waveform, and the less likely that
critical information or events will be lost. Tektronix recommends
at least 5X oversampling to ensure signal details are captured
and to avoid aliasing.
Rule: Sample Rate > 5 x (Highest Frequency Component)
2
Record Length
Record length is the number of samples the oscilloscope can
digitize and store in a single acquisition. Since an oscilloscope
can store only a limited number of samples, the waveform
duration – or length of “time” captured – will be inversely
proportional to the oscilloscope’s sample rate. A longer record
length enables a longer time window to be captured with
high resolution.
Rule: Captured Time = (Record Length) / (Sample Rate)

Features and Analysis Capability
Tektronix oscilloscopes offer a range of features and analysis
capabilities. When choosing your scope, you should review
available triggers, waveform search tools, automated
measurements, and analysis packages such as serial bus
analysis, jitter and power analysis to ensure they meet
your needs.
