Did you figure it out? I'm also not sure what the "Arbitrary dB" is.

On a different note, is there any way of choosing which trace you want to be visible? It seems to me that both the gain and the phase traces are always visible. AFAIK the sds2000x plus has this option but what about the SDS1x04X-E ? Is this feature missing?

Didn't really figure it out, but the values for Arbitrary dB seem the same as dBV. I'm not seeing an option to disable either trace and always see both.

Yes, it's very annoying and I really don't see why the excluded this option for the 1104x-e. This sucks.

I am considering a Siglent SDS1202XE with SDG2042X - excited about the BODE PLOT II function and FFT along with a great oscilloscope - it would be my first new bench equipment in many years. 

My main initial application will be antique radio 456 kHz IF alignments with 2 and 3 stage variable BW IF's.  I've had some difficulty with my HP 141T spectrum analyzer and its 8443 tracking generator - and haven't found time to look into it.  I wanted "as-found" measurements before I start on these radios.  (I don't use that on simpler radios.) 

How practical is BODE PLOT II for a detailed look at these IF's?  I wonder if I would use sweep with demodulator probe to do real-time alignments, then follow up with the BP2 - or has anyone tried twiddling in small steps between waiting for another BP2 plot? 

FFT adds another dimension to it - would the FFT also be practical for a detailed look at these IF bandpasses?  Perhaps with noise input? 

I've read you can't really "replace" a good spectrum analyzer with BP2 in a multifunction "do-it-all" instrument - would I be much better off attending to my old HP141T combo for radio IF's?  (Then I would be curious about the phase data I could have had from BP2!) 

Or would this Siglent combo be a really good approach to this task?   



BillyO:
I'm not a tube guy myself, but if you can attach the equipment safely to the DUT it should work fine.

One suggestion though.  The SDG2042X seems like a bit of overkill if this is your main use case.  For a bit less money than the two you are looking at you could get an SDS2104XP scope and enable the internal 25MHz AWG.  This scope will also do the Bode plotting, has 4 channels, a much larger touch enabled screen, can use a mouse & keyboard, has more triggering options, has all the same serial decoding and can be enabled for more, has more advanced measurement functions, has more advanced math functions, has higher vertical resolution (10-Bit vs 8-bit) and can be set to work up to 500MHz.

Just something to consider.

Either way, I think you will be pleased.

The 2ch SDS1202X-E does not have BP as part of its feature set, maybe instead you meant SDS1204X-E ?

Actually the SDS2000X Plus range has an optional inbuilt 50 MHz AWG.

WPE, if as BillyO points out you instead consider a 2kX Plus do it soon before their $400 off promotion finishes at years end.
