Creating ISO 16750-2 Cranking Waveforms with a Siglent AWG and Tekbox TBDCA1

Automotive electronics must continue to operate when the vehicle supply voltage falls sharply during engine cranking. This application note shows how to create a representative ISO 16750-2 starting profile using a Siglent SDG6000X arbitrary waveform generator (AWG), a Tekbox TBDCA1 DC-coupled power amplifier and an oscilloscope. The method converts the required voltage profile into a CSV wavef...

Pass your EMC Test First Time

What’s inside: A punchy, practical guide to diagnosing and fixing EMC issues before the test house — with clear distinctions between narrowband vs broadband noise, real-world filtering advice, and PDN best practices. Radiated emissions: classify first, fix fast (narrowband lines vs broadband floor). Grounding & bonding: why filter specs collapse with poor return...

EMC Application Note – Part 3: Radiated Emissions Pre-Compliance for MIL-STD-461 & Automotive

Military and automotive radiated-emissions tests use the same measurement principles as commercial pre-compliance work, but the prescribed geometry, frequency bands, antennas, harness arrangements, bandwidths and detectors can be different. Always work from the applicable edition of the controlling standard and the agreed test plan. This page is a pre-compliance workflow guide. It does not re...

EMC Application Note – Part 2: Pre-Compliance Radiated Emissions — Making the Measurement

This part covers the measurement workflow for commercial, industrial and medical products: selecting a suitable site, recording ambient signals, configuring the antenna and analyser chain, and applying the corrections needed to express the result as field strength. Control the site and ambient environment Survey the site with the DUT switched off before relying on any result. Broadcast, mob...

EMC Application Note – Part 1: Equipment Needs for Radiated Emissions Pre-Compliance

Reliable radiated-emissions pre-compliance starts with a repeatable setup. The aim is not to recreate an accredited chamber on a small budget. It is to produce measurements that are consistent enough to identify problem frequencies, compare design changes and reduce the risk of an unexpected formal-test failure. Start with a defined measurement purpose: relative troubleshooting, margin estima...

Spectrum Analysers for EMC Testing — Key Takeaways

Electromagnetic compatibility testing is much easier to manage when emissions problems are found during development rather than at the test house. A spectrum analyser gives engineers a frequency-domain view of unwanted energy, helping them identify problem frequencies, compare operating modes and check whether a design change has improved the result. A spectrum analyser is not a complete compl...

TEKBOX Application Note: Using RF current probes with EMCview

RF current probes are useful for measuring common-mode current on cables without disconnecting the conductor. When the probe's frequency-dependent transfer impedance is entered into EMCview as a correction, a spectrum analyser voltage reading can be displayed as current in dBµA. Transfer impedance and transducer factor A current probe produces an output voltage in response to current throu...

Micsig | Application of Optical Isolated Probes in Testing High-Power DC Power Supplies

Third-generation semiconductor materials, especially Silicon Carbide (SiC) and Gallium Nitride (GaN), show great market prospects in electric vehicles, renewable energy, industrial power supplies, military and aerospace, fast charging technology, wireless communication, consumer electronics, and other fields. These materials have advantages such as high thermal conductivity, high breakdown field ...

Programming Example: Create a stair-step waveform using Python and PyVISA using LAN (SDG1000X, SDG2000X, SDG6000X)

The SIGLENT SDG series of arbitrary waveform generators can use waveforms created programmatically. The waveform data can be sent as individual samples formatted as binary little-endian, 2s complement values. In this programming example, we create a 10 point arbitrary waveform that starts at the least-significant bit and steps up to the most-significant bit to help with understanding the req...

Inter Modulation Distortion (IMD) testing

Two SIGLENT SDG owners and Amateur Radio operators and frequent experimenters, Steve Ratzlaff AA7U and Everett Sharp N4CY, got together and built a very thorough test procedure for testing Intermodulation Distortion (IMD) on a Loop Amplifier using a SIGLENT SDG2042X generator and SSA3021X spectrum analyser. IMD is an important test for verification of audio amplifiers and radio receivers as hig...

Multi Channel function generator synchronisation

1. Introduction Multi-channel function generators are useful in many situations. For example, in Radar testing the generator needs to output several phase coherent signals and for the phase to be independently adjustable for each signal. In 3-phase power line harmonic distortion testing, a 4 channel generator is required to simulate the multiple voltages and currents. 1.1 Problem A standa...
