Just to let you all know how happy I'm with my TinySA Ultra.

 

Hello all,

Yesterday i got a offer for RIGOL DSA815-TG (used 8 years old) for euro 675,00 (retail aprx euro 1300)
So basically a good deal and before I got my TinySA Ultra (and NanoVNA/LiteVNA) it was on the top of my "I want that in my shack" list.

The screen is bigger 8" vs 4", it has physical buttons for operating vs. touchscreen, build in tracking generator which the TinySAUltra doesn't etc,?

But after comparing it with the specs for PhaseNoise and DNAL

TinySAUlta
Phase noise at 30MHz and 10kHz offset ? ?-92dBc/Hz
Phase noise at 30MHz and 100kHz offset ? ?-108dBc/Hz
DNAL -153dBm/Hz (LNA Off) / -169dBm/Hz (LNA On) ?(DANL degrading in ultra mode 10dB above 2.5GHz, 25dB above 5.3GHz)

RIGOL DSA815
Phase noise 10kHz offset -80 dBc/Hz (frequency chart available in spec sheet)
Phase noise 100kHz offset -100 dBc/Hz ?
DANL -130 dBm (PA Off) / -150 dBm/Hz (PA On) 100KHz up to 1MHz.
DANL -135 dBm (PA Off) / -155 dBm/Hz (PA On) 1MHz up to 1.5GHz

I think I let it pass.?

Imho the feature wise the TinySAUltra covers them all and even adds new features like the waterfall etc. missing on the DSA815-TG. And in combination with my LiteVNA the tracking generator is covert to.?

So Erik, many thanks for designing these great tools and make them available to us for a reasonable price.?

I used my Ultra just this morning to measure the 3rd order IMD of my KX2. I used to have a DSA-815TG as well and don't miss it a bit.

It's an amazing device. I do a lot of work at microwave frequencies. It's invaluable to use to tune pipe cap filters up to 12 GHz. It's very easy to tune them to a wrong multiple of the input frequency in a frequency multiplier circuit.. With the TinySA Ultra, I can be sure I tuned to the correct harmonic.

It needs to be said.? Not only has Erik produced a great device, but he continues to provide superior after market support (i.e. this page and firmware updates).? I can't tell you how many times I've bought equipment with $ required for follow on support and that was IF support was available.

Many thanks Erik,? ?
