Analog Discovery Pro ADP3450

The Digilent Analog Discovery Pro ADP3450 is a portable 4-channel mixed-signal oscilloscope that delivers 14-bit resolution (16-bit with oversampling) at up to 500 MS/s, combined with a 16-channel logic analyzer, dual arbitrary waveform generators, and programmable power supply in a compact form factor smaller and lighter than a laptop. As the flagship of Digilent’s Analog Discovery Pro 3000 series, the ADP3450 bridges the gap between USB-connected instruments and traditional benchtop oscilloscopes — offering four true analog channels, Ethernet connectivity, and a built-in Linux automation mode for unattended measurement and test scripting.

Operating Modes

The ADP3450 supports three operating modes. In Standard mode, it connects to a host computer via USB or Ethernet and runs all instruments through the WaveForms software interface — oscilloscope, logic analyzer, spectrum analyzer, network analyzer, waveform generator, protocol analyzer, voltmeter, and data logger (up to 13 virtual instruments). In Linux mode, the ADP3450 boots its on-board Linux environment, enabling autonomous measurement, scripting, and automation without a host PC — engineers can SSH in, run Python scripts, and collect data from remote or unattended installations. Ethernet mode provides network-attached instrument access for distributed test setups.

The four true analog channels with 14-bit resolution and +/-25 V input range handle the most common oscilloscope tasks — monitoring power rails, debugging serial buses, and characterizing analog signal chains — while the 16 digital channels provide simultaneous logic analysis on a shared timebase. The 32 MS per-channel buffer supports extended captures for protocol analysis and intermittent fault detection.

For engineering teams that need portable, high-resolution mixed-signal measurement with remote automation capability — production test stations, field service diagnostics, or distributed monitoring setups — the ADP3450 provides benchtop-class performance in a form factor that travels with the engineer. GSAS Micro Systems provides the ADP3450 alongside the full Digilent Analog Discovery Pro lineup, with guidance on instrument selection and WaveForms automation integration for test and measurement applications across India.
