Everyone,

I skimmed through this thread which someone from YouTube pointed me to. (Thanks for that!)

Please note that you are correct about the calibration power & ECal requirements. The clip where I show the setup does not show a good calibration. I did several calibrations with different powers & ECals modules. One of my ECals allows up to 20dBm of incident power.

If you calibrate at one power and the measure at a different, the instrument warns you about it (as it should). The results will deviate of course, but this is sometimes needed; especially for active devices.

The TDS/SA options needed some work. The built-in synthesizer in conjunction with SA is very useful as well. I am working with them to improve the usability Part 2 of the review will cover those aspects.

Hello,
I have a question to anyone that own a SNA5000a.

Does it really fit within the specs, (see this doc => https://static.eleshop.nl/mage/media/downloads/SNA5000A_DataSheet_DS09050_E01B.pdf )
- on the bottom end of the BW (from 9kHz to 1MHz let's say) ?
  for instance, within BW 30k to 100k, the datasheet mention a dynamic range of 98dB (see page 8 & 13). Is it the right figure ? Or in fact the SNA performs a bit better ?
- and when we use a minimum IFBW (10Hz) ? measurements are in line with the datasheet too ?

It's for PDN measurements, that's why I ask about low freq range, although I'll use the full BW of the SNA5002a (up to 4.5G), this is the model I plan to buy. 
Sorry about these basic questions... I'd like to be sure that this "entre-level" 5002a is in line with the 3 others SNA, given that the price tag of the SNA5002a is very attractive (vs other 4.5G VNAs) ; especially vs the SNA 8.5G or even the 4 ports 4.5G model where price jumps by 2x or 4x...)

Thanks for feedback. 
Regards

Kick me please, I have not been keeping up with the firmware updates for these models. :horse:
There have been 2 in the last few months so I will list both release notes but only link in the latest version as it is the only one you need to install.

Version V1.0.0.2.10R9
70MB
https://int.siglent.com/upload_file/zip/firmware/Vector%20Network%20Analyzer/SNA5000A_V1.0.0.2.10R9.zip

10R9 Release notes
1. Added scalar mixer measurement function
2. Adjusted and optimized the spectrum analysis measure interface

10R8 Release notes
1. Added Freq Offset function
2. Optimized some functions of spectrum analysis
3. Added status bar to display smooth status
4. Added advanced mode for bandwidth search, support frequency percentage bandwidth setting function
5. Optimized the Marker->Delay algorithm

How has your experience been working with them as what sounds like a technical consultant?  Are they paying you in something other than free equipment?

@tautech,

What's this new SMM option for?
