The DLA-16 Plus and DLA-32 Plus are USB 3.0 logic analysers that capture 16 or 32 digital channels at up to 1GHz sampling rate, with 4Gbit of hardware memory and 170+ protocol decoders in the PC software. Buffer, stream and roll modes let you choose between full speed captures and long recordings, and adjustable thresholds cover logic from 1.2V to 5V.
Features and Benefits
- Up to 1GHz sampling and 2ns minimum pulse width - catches narrow glitches and fast edges
- 4Gbit DRAM buffer plus USB 3.0 stream mode - short full speed bursts, or single channel recordings of over 4 hours at 1MHz
- Threshold adjustable from -5V to +5V in 0.1V steps - matches 1.2V, 1.8V, 3.3V and 5V logic families
- Inputs withstand -40V to +40V with ESD protection, 250kΩ and 15pF input impedance - safer probing with light circuit loading
- 4 channel PWM output, 3.3V, 1Hz to 20MHz - drive a clock or test signal into the circuit without a separate generator
- Edge, level, parallel and serial triggering with custom protocol support - isolate the exact bus event you need
- 3 colour status LED - red disconnected, green connected, blue capturing
Applications
- MCU and embedded firmware debugging
- FPGA design verification and timing checks
- I2C, SPI, UART and other bus protocol analysis
- Digital circuit fault finding in repair, development and teaching labs
In the box
1 x DLA-16 Plus or DLA-32 Plus logic analyser, 4 sets x 5 shielded cables, 1 x USB 3.0 data cable, 18 x mini IC test hooks, 10 x IC test hooks, 1 x transparent storage case for the hooks, 1 x storage bag, user manual and packaging box.
Note: Keep channel inputs within -40V to +40V and never connect them to mains. Use a USB 3.0 port for stream mode; at low sample rates the maximum stream depth depends on the memory of the computer.

Q: What is a logic analyser used for? A: A logic analyser records many digital lines at once and decodes them into readable bus data, which helps find timing faults and protocol errors. The DLA-16 Plus and DLA-32 Plus capture 16 or 32 channels at up to 1GHz and decode 170+ protocols.. Q: What is the difference between buffer and stream mode? A: Buffer mode captures into the 4Gbit on-board memory at full speed, for precise timing and short events. Stream mode sends data continuously over USB 3.0 for long recordings, for example 13 minutes at 20MHz or over 4 hours at 1MHz on one channel.. Q: Which logic levels can it read? A: The threshold is adjustable from -5V to +5V in 0.1V steps, covering logic from 1.2V to 5V. The seller recommends setting it halfway between the high and low levels of the signal.. Q: Does it need a USB 3.0 port? A: It connects by USB Type-C and a USB 3.0 port is recommended, especially for stream mode, which transfers data to the computer while it captures.. Q: Can the logic analyser output signals too? A: Yes. It has 4 PWM outputs at 3.3V, adjustable from 1Hz to 20MHz with a settable duty cycle, useful as a clock or test source..
