Siglent Test & Measurement Equipment

Innovative features and functionality backed with quality and performance.

Whether you are a professional engineer, a repair technician, or an electronics hobbyist, it's essential to have the right tools and test equipment on your workbench. Having an organized workspace is key to being productive but having your tools at arm's reach is just as important. Some test equipment can serve many purposes while other devices are designed for specific testing needs. You don't necessarily need to spend a lot of money, and you may not need all the bells and whistles, so we have listed some fundamental pieces of test gear and their uses to help you determine what is best for your test bench.

DC Adjustable Power Supply

DC-Adjustable-Power This type of power supply is larger than your typical wall-wart (wall adapters) or line-lump (table-top) power supplies.  Even though some plug-in type and enclosed supplies can supply more than one voltage, that voltage is normally a fixed output.  Rather than maintain a collection of single-output power supplies and an assortment of cords and plug adapters, this is an indispensable tool to have on the bench if you routinely work with a variety of voltages.  These bulkier supplies typically have fixed and/or knob-adjustable output voltage and current range and an analog or digital display for visual power output confirmation.  Benchtop power supplies can have more than one output channel and use binding post terminals for connecting test leads, probes, and other cables.  They also have a cleaner and more professional look on the bench.  A great example is the SPD3303C 220W Programmable DC Adjustable Power Supply from Siglent.

Digital Multimeters (DMMs)

DMM A digital multimeter is many meters in one with a digital display.  There are still analog models, but the majority are digital to support more functions and provide better resolution.  Every electrical engineer or student should have one, for they are one of the most useful pieces of test equipment.  The number of functions vary among multimeters, but the SDM3045X benchtop style DMM with true-color 4.3" TFT-LCD can measure AC and DC voltage, AC and DC current, resistance, frequency, capacitance, temperature, diode test, and continuity.  Additional features to consider are the 4.5 digit 60,000 count display, min/max/avg and hold functions that allow you to capture the signal to analyze without having to keep to probes on the device under test.  If you need more performance, automatic measurement or more digit resolution, the dual-display 5.5 digit 240,000 count SDM3055 should fill your high-precision measurement needs.


OSCIll An oscilloscope is a crucial piece of test equipment when you need to display electrical signals over a relative time period.  Where a DMM can only measure, the oscilloscope is a visual tool to view signals for testing and fault-finding.  The box might look like a tiny TV from generations ago; however most manufacturers have transitioned from CRT tube displays to thinner, lighter and larger TFT-LCDs.  The Siglent SDS1202X-E offers a high feature-to-price ratio with 200 MHz bandwidth, real-time sampling of a billion samples per second (1 GSa/S) and a standard record length of 14 Mpts.  It supports high-speed hardware-based pass/fail function, SCPI remote control commands and is easy to use with the most commonly used functions accessible on the user-friendly front panel.  The SDS1204X-E super phosphor oscilloscope has four channels and dual 1 GSa/s ADCs with a large 7" TFT-LCD.

Function Generator

Generator An oscilloscope is a type of signal analyzer, but the function generator, or arbitrary waveform generator, is a signal source.  It can produce a definable voltage over a definable time to create sine, square and other pulsed waveforms. The dual-channel SDG1032X from Siglent has a bandwidth up to 30 MHz with 150 MSa/s sampling rate, 14-bit vertical resolution, and 16 kpts wavelengths.  The innovative EasyPulse technology means it's capable of generating lower-jitter pulse waveforms. All the waveforms displayed on a crisp 4.3" color TFT-LCD.  If you crave more signal and resolution, the 40MHz SDG2042X is dual channel but with a whopping 1.2GSa/s maximum sample rate, 16-bit vertical resolution and wavelengths from 8pts to 8Mpts.

Programmable DC Electronic Load

Programmable DC Electronic Load For technicians in automotive, alternative energy, and aerospace industries, programmable DC loads such as the SDL1020X-E fulfill one of many electrical testing needs. This helps technicians determine the efficiency and effectiveness of an electrical circuit. In test engineering or prototyping environments, DC loads are commonly used for test and measurement purposes. Some examples would be determining the current, voltage and/or frequency in a given electrical system and simulating load devices in order to anticipate how the systems will react to fluctuations in various parameters.

Some applications that involve DC load testing would include an analysis of current of converters, battery chargers, fuel cells, batteries, and a variety of telecommunications equipment.

Spectrum Analyzer

Spectrum Analyzer When working on radio frequency (RF) applications, it is best to work with the SSA302IX to understand the complexity of a given signal. Oscilloscopes displays signals in the time domain while spectrum analyzer displays a signal in the frequency domain. Signals are typically made up of multiple frequencies and extremely complex in a real-world application since most electronics operate between a certain frequency bandwidth. A common issue when dealing with RF circuits is radio frequency interference (RFI) or electromagnetic interference (EMI) since a spectrum analyzer can be used to locate the frequency and nature of a signal that may be causing an interference. For engineers in the wireless, digital signal processing, and telecommunications industries, a spectrum analyzer satisfies most of their needs when it comes to prototyping, design, and testing circuits that deal with high frequencies.
