Waveform capture and visualization
A rare combination: low-cost, fully self-contained audio analyzer and signal generator for true stand-alone operation — no external equipment required.
“The one and only stand-alone audio analyzer without breaking the bank“
Easy Calibration
Pre-calibrated using a 16-bit source (AWG) for both -10dBV and +4dBu ranges
Easily re-calibrate analyzer ADC with your own high performance external source
Self-calibration function for analyzer DAC
Loop-back connection (non-BNC version) when no cables connected for quick verification
PC Analysis & Captures
Supports PC analysis via USB serial and supporting software
Export data to CSV format and compare sweeps using the PC application
Simple Interface
Using a simple UI structure, there are no secret menus or controls that require reading an extensive manual
3.5” touch screen with 240x320 resolution for clear plots and data visualization

Accessories:
2x 1/4” jack cable (jack version)
2x BNC cable
2x BNC to RCA converter
2x RCA to 1/4” jack converter
1x USB-C PD to 9V DC + Polarity inverter cable
Can be used with the provided cables using a USB-C PD compatible charger supporting 9V output*
Recommended to use a low-noise external 9V DC ≥300mA center-negative adapter (not included)
These type of adapters are readily available at most music stores for guitar effects pedals.
* Please note that common USB PD chargers are not optimized for noise performance.
Therefore, expect non-ideal SNR performance, often caused by 50/60Hz mains hum and power supply switching noise.
The provided cable is included only as a convenient out of the box experience, to get you started.
All measurements on this page were performed using a low-noise external power supply.
Due to the small size of this company, and limited capabilities of carrying stock, the first batches will only include the USB PD cable.
We are currently in the process of validating some 9V adapters to give better recommendations and possibly offer them for sale on this website alongside products.
