Quick remote computer control using LXI Tools

Posted on: December 15th, 2020 by Doug Lovell
15/12/2020
Introduction: There are many options for people considering remote communication and control of test and measurement instrumentation. In most cases, a computer is used to communicate to test instrumentation using USB or LAN connections. The computer can configure the instruments, collect and organize data, and present it in a useful and flexible way. Remote control provides: Inc...

Python Example: Building an Arb with 16-bit steps (SDG2000X/SDG6000X)

The SIGLENT SDG2000X and SDG6000X feature 16-bit voltage step resolution. This provides 65,535 discrete voltage steps that can cover the entire output range (20 Vpp into a High Z load) which can effectively be used to test A/D converters and other measurement systems by sourcing waveforms with very small changes. In this example, we use Python 2.7 and PyVISA 1.8 to create a ramp waveform that i...

Resolver Simulation using an Arbitrary Waveform Generator

Posted on: December 15th, 2020 by Doug Lovell
15/12/2020
A resolver is an electromagnetic sensor that is used to determine the mechanical angle and velocity of a shaft or axle. They are often used in automotive applications (cam/crankshaft position), aeronautics (flap position), as well as servos and industrial applications. When designing, testing, or troubleshooting systems that use resolvers, it can be worthwhile to build a system that can easy si...

The basic output waveform and related parameters of the arbitrary waveform generator

Posted on: December 15th, 2020 by Doug Lovell
15/12/2020
Traditional function generators can output standard waveforms such as sine waves, square waves, and triangle waves. However, in actual test scenarios, in order to simulate the complex conditions of the product in actual use, it is often necessary to artificially create some "irregular" waveforms or add some specific distortion to a waveform. Traditional function generators can no longer meet the r...

Quickly Monitor FM Deviation using a Spectrum Analyser

Posted on: December 15th, 2020 by Doug Lovell
15/12/2020
Spectrum analysers are very useful tools for observing radio transmissions. One of the more common applications is to monitor a known channel or band of frequencies. In this note, we are going to show how to quickly capture an FM radio transmission and then configure the analyser to provide us with the frequency deviation of that signal. NOTE: If you are unsure of the power of the signal that y...

Electromagnetic Compliance: Troubleshooting with Near-Field and Current Probes

Posted on: December 15th, 2020 by Doug Lovell
15/12/2020
Electromagnetic interference (EMI) can cause a host of problems, especially when developing a product or attempting to pass mandatory electromagnetic compliance (EMC) tests. Garbled displays, bad data, or complete malfunctions can occur when a design is effected by EMI. To minimise the effects of interference, government agencies like the Federal Communications Commission (FCC) in North America cr...

Spectrum Analyser Basics: Bandwidth

Posted on: December 15th, 2020 by Doug Lovell
15/12/2020
Spectrum analysers are useful tools for broadcast monitoring, RF component testing, and EMI troubleshooting. There are a number of common adjustments available with many modern analysers that can optimize performance for a particular application. In this application note, we will introduce resolution bandwidth (RBW) and video bandwidth (VBW) and how they affect measurements. Resolu...

Spectrum Analyser Basics: Detectors

DIY Spectrum Analyser Input Protection

Posted on: December 15th, 2020 by Doug Lovell
15/12/2020
Spectrum analysers like the SIGLENT SSA3000X and SVA1000X series are extremely useful instruments that can provide invaluable insight into broadcast signal performance, transmitter troubleshooting, and interference as well as RF device characterization and EMC testing. But, like other spectrum analysers, they are very sensitive and can be damaged easily, if the proper precautions are not follow...
