8 Hints for Making Better Measurements Using RF Signal Generators

8 Hints for Making Better Measurements Using RF Signal Generators

Signal sources provide precise, highly stable test signals for a variety of component and system test applications. Signal generators add precision modulation capabilities, and are used to simulate system signals for receiver performance testing. This guide helps you improve the accuracy of your measurements that involve using RF signal sources. You may increase the accuracy of your data by using more than one of the hints in your test setup.

General Connector Information

General Connector Information

Many coaxial connector types are available in the RF and microwave industry, each designed for a specific purpose and application. For measurement applications, it is important to consider the number of connects/disconnects, which impact the connector’s useful life. A few connectors, such as the APC-7, are designed to be sexless. Most are female connectors that have slotted fingers, which introduce a small inductance at the interface. The fingers accommodate tolerance variations but reduce repeatability and may ultimately break after 1000 connections. The following is a brief review of common connectors used in test and measurement applications

8 Hints for Making Better Spectrum Analyzer Measurements

8 Hints for Making Better Spectrum Analyzer Measurements

The spectrum analyzer, like an oscilloscope, is a basic tool used for observing signals. Where the oscilloscope provides a window into the time domain, the spectrum analyzer provides a window into the frequency domain. These hints will give you some way to make better spectrum analyzer measurements

8 Hints for Making Better RF Counter Measurements

8 Hints for Making Better RF Counter Measurements

At first glance, an electronic counter seems like a fairly simple instrument. You connect a signal to the input, and a digital readout tells you the frequency or some other parameter. While we’d like to say that counters are a plug-in-and-go sort of instrument, the technical realities of quartz-crystal timebases demand some care and attention on your part. The counter, its timebase options, your signal, and the way you set up the measurement all affect the quality of the results. In fact, so many factors play into the equation that the accuracy specification for a good counter is literally that—an equation. The good news is that a little attention goes a long way toward better measurements, and these eight hints are a great place to start.

The Signal Generators

The Signal Generators

The signal generator, or signal source, is the stimulus source that pairs with an acquisition instrument to create the two elements of a complete measurement solution. The two tools flank the input and output terminals of the device-under-test (DUT). In its various configurations, the signal generator can provide stimulus signals in the form of analog waveforms, digital data patterns, modulation, intentional distortion, noise, and more. To make effective design, characterization, or troubleshooting measurements, it is important to consider both elements of the solution.
