FNIRSI DLA-16 Plus - 16-channel 1GHz USB 3.0 logic analyzer

Description

The FNIRSI DLA-16 Plus logic analyzer supports 16 digital channels and sampling rates up to 1 GHz, making it suitable for analyzing high-speed digital buses, timing relationships and short pulses. In Buffer mode, sampling up to 1 GHz is available for 1 or 8 channels, while all 16 channels can operate simultaneously at up to 500 MHz. The 4 Gbit hardware memory enables high-speed capture of large data blocks, while the USB 3.0 interface provides data transfer rates up to 5 Gbps between the analyzer and a computer.

Buffer, Stream and Roll modes allow the acquisition method to be adapted to the analyzed signal. Buffer mode is intended for high-speed capture using onboard memory, Stream mode enables longer data transfer directly to the computer, while Roll mode allows real-time waveform observation. In Stream mode, the DLA-16 Plus supports up to 1 GHz for one or two channels, 500 MHz for 4 channels, 250 MHz for 8 channels and 125 MHz for all 16 channels.

DLA-Logic software supports decoding of more than 120 protocols and measurements of pulse width, period, frequency, duty cycle and time differences between channels. Level and edge search, measurement markers, CSV and BIN data export and project saving are also supported. The open protocol library allows support for additional standards to be extended.

The inputs support an adjustable logic threshold from -5 V to +5 V in 0.1 V steps, allowing operation with circuits using different voltage levels. Input protection provides a withstand range from -40 V to +40 V, while the minimum detectable pulse width is 2 ns. The analyzer supports rising-edge, falling-edge, high-level, low-level and any-edge triggering. Advanced serial and parallel triggering is available only on the DLA-32 Plus and does not apply to the DLA-16 Plus.

The DLA-16 Plus also provides a 4-channel 3.3 V PWM output with a frequency range from 1 Hz to 20 MHz, useful for testing digital inputs and simple control circuits. The enclosure measures approximately 90 x 81 x 11.5 mm, while connection to a computer is provided through USB-C with a USB 3.0 interface. A three-color LED indicator shows connection and data capture status.
