The Usbee QX is the sweet spot for makers and junior engineers who need more than 8 channels but cannot afford a Saleae or DSLogic. It is significantly more robust than the ultra-cheap FX2LP dongles that lack buffer memory.
(and its associated software suite) represents a significant era in portable electronic diagnostic tools, designed by CWAV to bridge the gap between benchtop hardware and PC-based analysis. The Versatility of the USBee QX
Because sigrok supports command-line tools ( sigrok-cli ), you can integrate the Usbee QX into Python or Bash test scripts. Example: trigger on a rising edge, capture 100,000 samples, and search for a specific hex pattern. If found, pass the test.
The Usbee Qx utilizes an FPGA to handle the high-speed sampling. The FPGA acts as a hardware accelerator, capturing digital signals at precise intervals and buffering them before sending them to the PC software. This allows the Qx to achieve a real-time sample rate of up to 24 MHz, which is crucial for capturing fast digital edges and high-speed protocols like SPI at higher clock speeds. Usbee Qx
Most cheap logic analyzers rely on simple microcontrollers to sample data. This approach creates a bottleneck; the microcontroller can only process data as fast as its internal clock allows, and it struggles to stream high-speed data to the PC quickly.
This is where the Usbee QX shines or falters depending on your choice. The official "Usbee Suite" is functional but dated. The real power comes from . The Usbee QX uses the common FX2LP chipset, meaning it is natively supported by the open-source sigrok project. PulseView offers:
To truly understand the Usbee QX, let’s break down its technical DNA: The Usbee QX is the sweet spot for
The primary function of the Qx is to capture and display digital signals. With 16 channels, it can monitor complex data buses. It supports a sample rate of 24 MSPS (Mega Samples Per Second). According to Nyquist-Shannon sampling theorem, one should sample at least 4 to 10 times faster than the signal frequency to accurately capture edges. Therefore, the Usbee Qx is comfortably capable of analyzing:
At its core, the Usbee Qx is a USB-based test and measurement instrument. Unlike traditional benchtop oscilloscopes or massive logic analyzers that occupy half a workbench, the Usbee Qx is housed in a small, dongle-like enclosure. It draws power from the USB port of the host computer, making it an exceptionally portable solution for field work or cramped workspaces.
