content: This was the first SML03 (unit 1) in the SML thread:https://www.eevblog.com/forum/testgear/rohde-schwarz-sml-series-signal-generators-sml01-sml02-sml03-smv03/It has the B19 option, which I don't like (I prefer the front ports). I used the output module (attenuator) and screen to repair another unit.The PSU, mainboard, and 2G/3G boards all work fine (as see in the thread examples). Replace the screen and either replace or repair the output module, and it should be good to go. People smarter than me suggest that the 4227T switches (actually SSW-124) are what's likely wrong with the attenuator in the output module. Utsource.net supposedly has them in stock.Or use this SML03 for parts to fix another one. 🤔I dunno what a good price is. Let's say$600 orbest offer, buyer pays actual shipping. I am open to trades.Probably US only, unless I know you, and you want to pay stupid ass tariffs. 🙄Thanks,Josh

content: Quote from: johnh on May 30, 2025, 08:37:59 amNot a dumb question at all! The SML series is modular. The real difference between the SML01 and SML03 is the 2G/3G module. If you have the SML01 with a good screen and output module, you should be golden.If the SML01 is all good, you could first try installing the 2G/3G module from the SML03 parts unit (and the faceplate) into the SML01 unit. I'm curious if inserting the 2G/3G module instantly makes it an SML03, or if you need to do some magic* first. You can jump on the SML thread if you need help messing with it.Thanks,Josh* = magic probably means something like replacing the battery/clearing the memory, and maybe starting up the SML while holding down the 1 key.

content: P.S. I dunno if you would need the mainboard from the SML03 for the factory calibration data or not. You could experiment with it, and run the full self calibration (Protect - Password 1 - 123456 first), and see how it does.

content: I just saw this in the service manual. It looks like the 2G/3G module multiplies the 1.1GHz mainboard to get the higher frequencies.

content: Its tempting. But, with state of the AUD to USD and I have to another round of treatment for a cancer, that has relapsed.I am putting a few things on hold.

content: Make an offer!I'm flexible on the price, I need this out of my office. Cash or trade, buyer pays actual shipping cost.If you have a working SML01 or SML02, you can use parts from this to upgrade to 3.3GHz, or you can repair this unit.Thanks,Josh

content: The cables going to and from the output/attenuator unit are no longer included (that means the output cable with the N connector is not included, and the short little guy going from the 2G/3G module to the output unit).I need the space, go ahead and lowball me if you want. Buyer pays actual shipping fees.Thanks,Josh

content: The side handle is no longer included.If you have an SML01, the working 2G/3G module should be all you need (plus connectors) to upgrade to 3GHz.Thanks,Josh

content: I boxed the parts unit up. The box is 20x20x8 (inches), and weighs 21 pounds. If anybody wants to get a shipping quote, I'll probably ship from Sturbridge, MA, 01566 USA.Thanks,Josh
