  Quite interesting that they put LEDs in the RF section – there’s quite a few of them too!

  Didn’t bother counting, but here’s a couple images with them:

  Hi Dave!

  Thank you very much for the eagerly awaited teardown of the DSA815-TG. Now I know that the christmas gratification is not misspent. Well done, thumbs up and keep going!

  Best regards from Hamburg, Germany
  Martin

  From the pinout, the ADC chip looks like LTC2245 (or the other part # from this series with a different speed grade – 2246, 2247, 2248, 2249, 2254, 2255), but definitely a 14-bit device.

  Great teardown! I noticed that there are routed slots associated with each filter. Are these for thermal relief?

  Nice! U103 (the QFN without any markings at 16:55) looks like a variable attenuator from peregrine (PE4306) with 5 bit resolution.
