Complete Calibrated STEMlab 125-14 Kit

The IZD0004 package includes the STEMlab 125-14 digitizer together with the hardware needed for a wide range of electronics and RF measurements. It is suitable for engineers, universities, radio amateurs, laboratories, and developers who want more than the basic board-only configuration.

Dual 14-Bit 125MS/s Analog Inputs

The STEMlab 125-14 provides two simultaneous analog input channels with 14-bit ADC resolution and sampling rates up to 125MS/s.

• 2 analog input channels
• 125MS/s sampling rate
• 14-bit ADC resolution
• DC to 60MHz analog bandwidth
• 1MΩ input impedance
• DC-coupled inputs
• Selectable ±1V and ±20V full-scale ranges

The combination of high resolution and wide bandwidth makes the platform suitable for oscilloscopes, data acquisition, RF experiments, signal analysis, and general-purpose electronics measurements.

Dual 14-Bit Signal Generator Outputs

Two integrated DAC channels allow the STEMlab 125-14 to generate test signals directly from the same device.

• 2 analog output channels
• 125MS/s sampling rate
• 14-bit DAC resolution
• DC to 60MHz output bandwidth
• ±1V full-scale output range
• 50Ω load impedance
• Short-circuit protection

This allows the platform to operate as both an oscilloscope and signal generator without requiring separate bench instruments for many common development tasks.

Xilinx Zynq-7010 FPGA and ARM Processing

The STEMlab 125-14 is built around the Xilinx Zynq-7010 SoC, which combines programmable FPGA logic with a dual-core ARM Cortex-A9 processor.

This architecture allows high-speed signal processing to be handled in FPGA hardware while Linux applications, networking, control software, and user programs run on the ARM processor.

Oscilloscope and Signal Generator

The browser-based oscilloscope application enables real-time waveform visualization, measurements, triggering, and signal generation. It can be used for circuit debugging, sensor analysis, waveform testing, and general electronics development.

Spectrum Analyzer

The STEMlab 125-14 can also operate as a spectrum analyzer, allowing users to inspect signals in the frequency domain and evaluate harmonics, interference, noise, and frequency components.

Bode Analyzer

The Bode Analyzer application can measure the gain and phase response of filters, amplifiers, control systems, and other devices under test using the integrated signal generator and measurement inputs.

Logic Analyzer Included

The Calibrated Kit includes both logic analyzer probes and the Logic Analyzer Extension Module, allowing the STEMlab platform to capture digital signals and decode common serial protocols.

• I2C decoding
• SPI decoding
• UART decoding
• CAN analysis support

Software Defined Radio

The STEMlab 125-14 can be used for software-defined radio applications and is compatible with SDR development environments such as GNU Radio and HPSDR-compatible software.

This makes it suitable for RF experimentation, amateur radio, digital signal processing, receiver development, and educational communications projects.

Streaming and Remote Acquisition

Signal data can be streamed to a remote computer or stored to compatible local media, making the platform useful for long-duration measurements, monitoring systems, automated experiments, and remote laboratories.

Calibration Support

The STEMlab platform includes calibration functionality for improving DC and frequency measurement accuracy. The Calibrated Kit is designed for users who require a complete measurement setup with the accessories necessary for practical laboratory use.

Gigabit Ethernet and Wi-Fi Connectivity

Gigabit Ethernet provides fast network connectivity for remote access, browser-based applications, data transfer, and automation. The included compatible Wi-Fi dongle also enables wireless network access where a wired Ethernet connection is not convenient.
