Rohde & Schwarz FPC1500 (FPC-COM2 kit) or Siglent?

Now for those that don't have this equipment this is is what the "log mode" is like:
And this is what a real log in frequency mode means to me:
I have both a SVA1032x and a FPC1500, and the former is like 10x more capable.

FYI, go to the Display menu and change the default Inverse screenshot setting :horse: to Normal. ;)
Love my SVA1032X too despite having the substantially more expensive SNA5004A as well.
150mm WiFi antenna getting a 10001 point Mag Loss full 3.2 GHz frequency sweep and marker set to Continuous Valley. Display menu open FYI.
Log axis set for shits and giggles.

Thanks but I have it on purpose since I sometimes print the responses in paper.

None of the Advantest spectrum analysers I have (owned) have log sweep, so the feature isn't as common as you might think.
Also look at the difference in RBW from the pictures you posted. The R&S is set to 200Hz while the Siglent is set to 300kHz.

That's only a User setting and here's another an order of magnitude better.
nctnico:
@tautech: your RBW is still at 30kHz. Not 200 Hz. Also the start frequency is at 9kHz, not 100Hz. In the end the images PartialDischarge has posted are not comparable in any way. Also look at the sweep times; with comparable RBW the R&S method still is quick while the Siglent is taking ages. Likely the Siglent does a linear sweep and plots the data on a log scale.
It would be interesting to see a log sweep from the FPC1500 with a higher RBW setting.
