What about using the DL0102G\/XN (the “G” and “GXN”) with or without the IF2C in Continuous Acquisition mode in your UT software? In Brief:<\/strong> Yes.<\/p>\n\n\n\n\n\n\n\n

Continuous Acquisition (CA) is different from fast channel-switching round-robbin rapid-scan<\/a> because it keeps the channels fixed and acquires pulse and receive waveforms on the same channel or channels (two channels, if cross-channel CA is enabled) continuously and fairly rapidly.<\/p>\n\n\n\n

Continuous Acquisition (CA) Controls<\/figcaption><\/figure><\/div>\n\n\n\n

The DLITE-Family Host boards, including the DL0100A1, DL0102G, and DL0102GXN, are all capable of sustained pulse and received speeds of up to 60Hz.<\/p>\n\n\n\n

However the limitation in continuous acquisition speed is typically or has been: (1) Serial communications bandwidth (typically maxing out at somewhere around 1Mbps using a capable USB-Serial cable) and related flow control and (2) UT software PC processing rate.<\/p>\n\n\n\n

As of this writing, circa Mar 2019, the limitation in activating and testing CA with a G\/XN board has been that the UT software verifies the Host board’s firmware revision before continuing (which is a very useful thing to do). However, the G\/XN boards ship with demo firmware that uses a different firmware revision format. This is by design to indicate that the firmware as shipped, although built from the same base code as your custom in-house firmware, is a different branch and may or may not include your latest additions, and has been updated to demo the latest stock hardware features and APIs.<\/p>\n\n\n\n

Since CA is included in the firmware base, that function should be functional as shipped, and if you modify your UT software, say an R&D release of it, you may see the usual CA functionality.<\/p>\n\n\n\n

However, if your UT software and in-house custom firmware implementations of CA have changed, then you may need to simply integrate the latest stock hardware features and API into your firmware code base<\/a> and re-release the firmware to match your system implementation. It’s reasonably fast, and since all the demo code is here for the IF2C API<\/a>, you can drop it in and play from there. Maybe a day.<\/p>\n\n\n\n

Any questions or something doesn’t match what’s written here, just get in touch.
