This ranked list targets analysts and operators who need verifiable control mechanisms like configuration models, editor workflows, and automation interfaces, then compare tool fit without mixing vendor-specific feature marketing.
Siglent EasyWave
vertical specialistPC-based waveform creation and editing software for Siglent arbitrary waveform generators.
EasyWave builds waveform sequences and emits instrument control sequences tailored to Siglent generator command expectations over LAN.
EasyWave provides a waveform editor for building amplitude versus time shapes and configuring sweep and trigger behavior for function generator output. It also supports waveform sequencing so multi-step output plans can be staged and pushed to the instrument without manually retyping settings. EasyWave is a good fit for workflows that need repeatability across lab sessions because it can re-emit the same command set after edits.
A concrete tradeoff is limited external integration depth compared with full instrument control stacks, because EasyWave centers on generating instrument-ready waveform definitions rather than exposing a broad automation API surface. It works best when a single user or a small bench needs to update waveforms and immediately validate output using the generator’s on-device playback.
- +Waveform sequencing cuts manual reconfiguration between test steps
- +Sweep and trigger parameters map cleanly into instrument control
- +Waveform editor workflow supports fast iteration and validation
- +SCPI command generation helps automate repeated instrument setups
- –Automation depends on export and command workflows rather than a broad API
- –Advanced multi-instrument orchestration needs external tooling
- –Complex modulation chains take time to model accurately in editor

How to Choose the Right function generator software
Function generator software supports arbitrary waveform editing, sweep and trigger configuration, and waveform sequencing that maps to how a generator actually plays back output. This guide covers Siglent EasyWave, Digilent WaveForms, NI InstrumentStudio, Tektronix ArbConnection, and seven additional options that target lab automation workflows.
Across the included tools, the strongest differentiator is how the software couples waveform construction to instrument execution using either device-linked command workflows or scriptable APIs. The evaluation also tracks which tools keep sequencing editable as one run plan versus offloading orchestration to exports or external scripts.
Function generator software for arbitrary waveform editing, sequencing, and instrument control
Function generator software lets teams build arbitrary waveform shapes, define sweep and trigger settings, and package those into repeatable run plans that a generator can execute. The software focus is often on how waveform sequencing and output control connect to the target device behavior rather than on general-purpose UI features.
Siglent EasyWave builds waveform sequences that emit instrument control sequences tailored to Siglent generator command expectations over LAN. Moku Python API takes the opposite shape by exposing parameterized waveform configuration and execution through Python calls, which enables automated replay but requires careful state management for complex sequencing.
What differentiates function generator control and sequencing software
Function generator software stands or falls on how it couples waveform construction to the generator execution path, including how sweep and trigger settings are preserved when outputs are replayed. That coupling shows up most clearly in waveform sequencing behavior, because the sequence must remain editable or it must export into a command workflow without losing timing intent.
Device-linked instrument control workflows
Siglent EasyWave builds waveform sequences that emit instrument control sequences tailored to Siglent generator command expectations over LAN. Tektronix ArbConnection coordinates editing results with device playback settings for repeat runs on Tektronix generators.
Single-UI workflow that keeps sequencing aligned to generator configuration
NI InstrumentStudio keeps waveform content editing and sweep and trigger configuration in one workflow for repeatable runs on NI-centric setups. PicoScope 6 synchronizes generator configuration and output behavior to PicoScope acquisition and trigger timing inside one UI.
Editable sequencing plans that stay intact across iterations
Visual Analyser provides waveform sequencing that stays editable as one run plan across iterations. WaveForms supports an editor-first workflow with trigger and sweep-style controls designed for repeatable stimulation runs on Digilent hardware.
Automation surface for scripted parameterization
Moku Python API exposes waveform configuration and execution through Python calls that parameterize and replay setups. PicoSDK supports an SDK-style driver workflow that enables repeatable automated output parameter setting through Pico-style calls.
How to choose function generator software by execution coupling and automation needs
Start by mapping the intended execution path to the software’s coupling model, since some tools generate device-specific command workflows while others center on a UI that mirrors generator configuration. Then validate how waveform sequencing behaves when test steps change, because sequencing that stays editable reduces rework compared with sequencing that must be re-exported into external automation.
Pick the execution coupling model that matches the bench control path
Choose Siglent EasyWave when LAN-based instrument control sequences must be tailored to Siglent generator expectations with waveform sequencing that drives repeatable steps. Choose NI InstrumentStudio when the lab needs NI-style trigger and sweep configuration living inside the same workflow that edits waveform content.
Use an editor-first sequencing tool when run-plan iteration must stay inside the software
Choose Visual Analyser when the run plan must remain editable as a single sequencing plan across iterations without exporting glue. Choose WaveForms when a single PC workflow must support Digilent device output control with trigger and sweep-style repeatability.
Choose a device-linked loader when waveform playback timing must stay coupled to instrument settings
Choose Tektronix ArbConnection when repeat runs depend on instrument-linked waveform loading that coordinates editing results with device playback settings. Choose PicoScope 6 when generator timing must align directly with PicoScope acquisition and trigger timing from the same UI.
Switch to a scripting API when parameterized waveform configuration must be re-provisioned from code
Choose Moku Python API when parameterized waveform configuration and execution must be driven from Python with SCPI-style configuration and execution behavior. Choose PicoSDK when automation already follows PicoScope-style driver patterns and generator output parameter setting must be driven through that SDK structure.
Validate multi-channel synchronization and sequencing depth against the connected hardware
Choose TiePie Multi Channel software when phase-coherent multi-output timing alignment controls are required for synchronized multi-output sequences. Choose Spectrum SBench 6 when deterministic multi-step stimulus must run as an instrument-style bench execution workflow, while recognizing editor depth can slow fast iteration.
Who function generator control software is built for
Lab teams that run repeatable stimulus patterns need software that preserves sweep and trigger intent while packaging waveform sequencing into something the generator can execute reliably. Automation-focused teams need a clear boundary between waveform authoring and test execution, because sequencing complexity often moves from UI edits into export workflows or code state management.
Bench teams standardizing on a specific generator vendor interface
Siglent EasyWave matches Siglent generator command expectations over LAN and supports sequencing that emits instrument control sequences. Tektronix ArbConnection matches Tektronix waveform generator playback expectations through instrument-linked waveform loading.
NI-centric labs that require integrated sweep and trigger configuration
NI InstrumentStudio centers waveform editor and instrument configuration in one workflow so sweep and trigger mode settings connect directly to NI generator behavior. This reduces the need to bridge generator execution configuration across separate tools.
Systems teams building code-driven automated test plans
Moku Python API enables parameterized waveform configuration and execution through Python calls for replayable automated setups. PicoSDK provides a driver-integrated control workflow for automated output parameter setting aligned with Pico-style APIs.
Multi-output test systems that depend on timing alignment across channels
TiePie Multi Channel software includes built-in channel synchronization and timing alignment controls intended for phase-coherent multi-output generation. WaveForms and others depend on connected hardware capabilities for advanced channel synchronization.
Common pitfalls when selecting function generator software
The most frequent failures happen when waveform sequencing and execution coupling get treated as an afterthought, or when synchronization assumptions are made without checking how the connected hardware constrains timing. Another recurring issue is pushing large waveform payloads or complex sequences through a path that was not designed for throughput or state management, which leads to slow cycles and hard-to-debug test runs.
Assuming sequencing edits will survive into automated runs without checking the export or command path
Siglent EasyWave emphasizes sequencing that exports into instrument control sequences for Siglent over LAN. Visual Analyser keeps sequencing editable as a single run plan, which reduces the risk of mismatched run steps after edits.
Selecting a tool for waveform editing while ignoring that connected hardware determines synchronization depth
WaveForms limits advanced channel synchronization when the connected Digilent hardware cannot support it. PicoScope 6 limits function generator capabilities based on which PicoScope hardware model is connected.
Using Python or SDK control without planning for sequencing state management and payload throughput
Moku Python API requires careful state management for complex waveform sequencing and throughput drops when repeatedly pushing large waveform payloads. PicoSDK can keep automation repeatable through driver patterns but may restrict advanced waveform editing to what the driver exposes.
Overlooking multi-instrument orchestration requirements when the workflow is designed around a single ecosystem
NI InstrumentStudio centers on NI ecosystems, so non-NI setups require extra bridging work. Siglent EasyWave automates through export and command workflows rather than a broad API, so multi-instrument orchestration can need external tooling.
How We Selected and Ranked These Tools
We evaluated Siglent EasyWave, WaveForms, Visual Analyser, NI InstrumentStudio, Tektronix ArbConnection, PicoScope 6, TiePie Multi Channel software, Spectrum SBench 6, Moku Python API, and PicoSDK by separating waveform sequencing behavior and instrument execution coupling from basic editing convenience. Features took 40% of the weight, ease and value each took 30%, and the scoring favored tools that preserve sweep and trigger intent in the execution path rather than tools that only provide waveform drawing.
Siglent EasyWave earned the top rank because it turns waveform sequencing into instrument control sequences tailored to Siglent generator command expectations over LAN, which strengthens repeat execution. The overall ranking also treated API-driven parameterization in Moku Python API and driver-integrated PicoSDK as a distinct automation path even when advanced editing depth is constrained by the exposed interface.
