I have a Siglent SSA 3032X-R RTSA @ 3.2 GHz model.  With latest 3.2.2.5.1R1 firmware upgrade installed.

I'm encountering what seems to be a glitch when I'm in the RTSA mode.  I've been working with Ohio to troubleshoot the problem, but they've been unable to duplicate my symptoms on their instruments.

The problem has to do with the Max Hold function in the RTSA/Density mode.   It doesn't work on my RTSA unless the Averaging is first set to a value other than 1! 

I'm not sure if it is appropriate to discuss this topic on the forum?

Regards,

Hi Nelson,

congratulations for your SSA3000X-R unit - I am evaluating the purchase of one, too.
Could you share your experience with some screenshots of Digital Modulation Analysis (i.e. 64QAM, 25Msps Symbol Rate, 4 Points/Symbol, 2048 length) with max. BW available?
As far as I have understood from the specs, the unit should have total <150Msps in that mode.
So, a 100MHz BW should be feasible. However, I found a note in the specs saying that max. analysis BW is limited to 40MHz  :-//
In addition, is the unit still workable (or far too slow) in Digital Modulation Analysis with setting of 256QAM, 25Msps and 4096 meas. length?

Many thanks!
Rob

To follow up on my own post - I was able to demonstrate the problem on my instrument to Siglent Ohio.  Hoping for a firmware upgrade in the near future to remedy the problem.  This affected the Max Hold and the Averaging display in RTSA mode.

Hi tv84,

trying to upgrade the 3000X-R to 7.5GHz with keygen (option "3075") but without success - license rejected, however other options installed with success.

Help appreciated - many thanks!
