FNIRSI DLA-32 Plus - 32-channel 1GHz USB 3.0 logic analyzer

Description

The analyzer supports 32 digital channels and sampling rates up to 1 GHz, enabling the capture of high-speed digital buses, timing relationships and short pulses. In Buffer mode, sampling rates up to 1 GHz are available for 1 or 8 channels, 500 MHz for 16 channels and 250 MHz when all 32 channels are used simultaneously. The 4 Gbit hardware memory stores data during high-speed acquisition, while USB 3.0 provides transfer rates up to 5 Gbps between the device and a computer.

Buffer, Stream and Roll modes allow the acquisition method to be adapted to the type of signal being analyzed. Buffer mode provides high-speed acquisition using hardware memory, Stream mode enables longer data transfers directly to a computer, while Roll mode allows real-time waveform monitoring. In Stream mode, the DLA-32 Plus supports up to 1 GHz for one or two channels, 500 MHz for 4 channels, 250 MHz for 8 channels, 125 MHz for 16 channels and 50 MHz for all 32 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 DLA-32 Plus additionally provides advanced serial and parallel triggering, with up to 16 configurable parallel trigger levels.

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 voltage tolerance from -40 V to +40 V, while the minimum detectable pulse width is 2 ns. The analyzer also supports rising-edge, falling-edge, high-level, low-level and any-edge triggering.

The DLA-32 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 the connection and data capture status.
