A no frills blog post on the hardware features of the Analog Discovery 3 in less than 350 words for those of you that don’t have time for extra words.
– MSRP $379 USD
– Backwards compatible with Analog Discovery 2 projects — so long as it didn’t use the 1.8 V input setting for digital pins.
– Adjustable System Clock Frequency between 50 MHz and 125 MHz, allowing for up to a 125 MS/s simultaneous sampling rate on all channels for the analog inputs, analog outputs, and digital I/O.
– All instruments always available in every configuration. No more losing access to digital I/O when allocating more buffer to the Wavegen.
– USB Type C connection, USB 2.0 data rate. USB 3.2 Gen 1’s extra throughput didn’t add enough value in most applications.
– Two differential 14-bit resolution analog inputs with 9 MHz bandwidth at -3 dB when using the MTE cables. Up to 16 bit resolution when sampling at 1/4 of the system clock frequency. ±2.5 V and ±25 V input ranges. Maximum sample buffer size doubled from 16k to 32k per channel (64k when only using 1 channel). Hardware FIR filters for each input. Record mode rate increased to 10 MS/s. Digital loopback of Wavegen and Power Supply output supported.
– Two single ended ±5 V analog outputs with 14-bit resolution and 9 MHz bandwidth at -3 dB when using MTE cables. Maximum sample buffer size doubled from 16k to 32k per channel. FM/PM and AM/SUM buffers on each channel increased to a minimum of 2k samples with 16-bit resolution. Digital loopback of received Scope data supported.
– 16 digital I/O pins at 3.3 LVCMOS supporting 5 V inputs. Maximum sample size doubled from 16k to 32k per channel. All digital pins and the two trigger pins can have their Pull resistor configured.
– +5 V and -5 V power supplies now supply up to 800 mA (2.4 W) each. Integrated readback of the supplied voltage supported.

For those fact checking my word count, I am using Notepad++’s Summary feature including the Title of the post, but excluding the em dashes at the start of each line (because Notepad++ counts a printable character followed by a space or newline as a word, so phrases like “5 V” count as two words), and excluding the text beneath the line break that Marketing Manager and Content Manager told me was required to have in the post.
For the morbidly curious readers who didn’t stop as soon as the line break happened, in an alternate timeline, this post could have easily gotten under 200 words. You’d lose out on various clarification details and the post would be more aggressively toeing the “proper sentence structure” line than it already is (and would also start violating unit spacing conventions set forth by NIST), but you could get all those caveats from the Specifications, https://digilent.com/reference/test-and-measurement/analog-discovery-3/specifications, and the Reference Manual, https://digilent.com/reference/test-and-measurement/analog-discovery-3/reference-manual.
All the while ignoring the fact that both of those are way more than 350 words. 🙂
