Digilent Analog Discovery Pro ADP3450
The Digilent Analog Discovery Pro ADP3450 is a four-channel, 14-bit, 125 MS/s mixed-signal oscilloscope with 16 digital lines, two AWG outputs, up to 32 MS of memory per channel, and both USB and Gigabit Ethernet. It also has a Linux Mode that runs embedded Linux on the instrument itself, which suits remote and unattended tests.

ADP3450 software on macOS, Windows and Linux
WaveForms 3.25.1 (March 2026) supports the ADP3450 on macOS 12 or later (Universal build for Intel and Apple Silicon), on Windows x86 and ARM64, and on amd64 and arm64 Linux through .deb and .rpm packages. The WaveForms SDK installs alongside it. Digilent also publishes an armhf WaveForms runtime package for the ADP3000 series, used when the instrument runs in Linux Mode.
USB, Ethernet and Linux Mode
The ADP3450 connects to a computer over USB 2.0 Hi-Speed (Type B) or over Gigabit Ethernet, so it can sit in a rack or test cell away from the PC. In Linux Mode it runs embedded Linux on the instrument, and it has four USB 2.0 host ports that Digilent documents for use with supported Wi-Fi dongles. In Linux Mode the scope buffer is limited to 32,768 samples. The ADP3450 needs its auxiliary power supply in every mode.
Acquisition specs
All four BNC inputs sample simultaneously at up to 125 MS/s per channel, with a maximum oversampling rate of 0.5 GS/s per channel. Each input is single-ended and ground-referenced with two hardware ranges: 2 V peak-to-peak (±1 V) at 200 mV/div and below, and 50 V peak-to-peak (±25 V) above. Bandwidth is 55 MHz or more with a suitable probe, with a switchable 20 MHz limit. In the default Standard configuration the buffer is up to 32 MS per channel, or 128 MS when only one channel is used. The two AWG outputs are 14-bit, ±5 V and over 15 MHz bandwidth, and the 16 digital lines run from 1.2 V to 3.3 V logic, 5 V tolerant. The ADP3250 is the same instrument with two scope channels. Digilent’s price for the ADP3450 without probes is $1,360 at the time of writing.
DAQAtlas, which is in development, reads the ADP3450 through the WaveForms SDK and can put its four simultaneous channels in one run with slower multichannel DAQ hardware, the kind of setup the mixed-vendor DAQ bench article describes.
Questions
Does the ADP3450 work with a Mac?
Yes. WaveForms supports it on macOS 12 or later with a Universal build for Intel and Apple Silicon, over USB or Ethernet.
What is Linux Mode on the ADP3450?
It runs embedded Linux on the instrument itself so it can work without a host PC; in that mode the scope buffer is limited to 32,768 samples.
What is the difference between the ADP3450 and ADP3250?
The ADP3450 has four scope channels and the ADP3250 has two; Digilent lists no other specification differences.
