Why does an amateur radio operator need an oscilloscope?
A ham radio operator uses scope for many reasons like troubleshooting ham radios, RF power measurement, two-tone signal testing of a transceiver, final visual quality checking of transmitted signals, and many others. Amateurs cannot only expand their knowledge tremendously about radios by visualizing the waveforms at different stages in radio through oscilloscope but can also check the quality of transmitted signals before it hits the antenna. Many applications of scopes are offered in the field of evaluating modulated signal quality. A scope can easily look at a single sideband RF output for assessing various aspects like gain of microphone and compression.
What are the features and specifications when buying an oscilloscope for Radio Applications?
We have listed few essential set of measures that are used for selecting best oscilloscopes for your Radio RF lab which are as follows:
- Bandwidth: Bandwidth defines a range of frequencies that an oscilloscope can measure. Bandwidth is an important parameter for selecting an oscilloscope for ham radio shacks. The bandwidth should be five times higher than the max frequency of signals for an accurate representation of the signal waveform.
- Sample rate: High sample rate ensures greater resolution of the waveform which helps in providing an accurate representation of faster signals. High quality and details are important consideration aspects for troubleshooting the electronic equipment.
- Number of channels: Another important consideration when purchasing an oscilloscope for ham radio operators. It will determine the number of signals you can view and analyze simultaneously. The greater number of channels you have in the oscilloscope, the more signals you will be able to compare at a time. One application where this comes in handy is if you want to monitor digital circuits in your Radio and any associated timing considerations.
- Memory-depth/record length: Higher memory depth helps to store, display and analyze a wider portion or time duration of the signal. The greater the length of a record, the more detailed your analysis can be. This is a key specification for visualizing a complete signal’s modulation envelope and identifying elusive problems in the device.
- Advanced features: Availability of the FFT function and intensity graded display are also important. A ham radio operator can do two-tone signal testing – also known as IP3 test – using the fast frequency transform (FFT). This allows signals to be displayed in the frequency domain. The two tone test provides a measure of non-linearity of the RF module being analyzed.
