Based on the time-delays, the scope trace is showing 2 different signals at
the level-shifter, not input & output of the same bit.
Double-check the control bits; it's very easy to make a mistake with POL,
BL, and LE.

Could you test "All on/All off" which does not need any data or clock? See 3rd
page of the datasheet. This should always work, otherwhise the chip might be
defective.
If you want, i can provide an arduino code that should work with this chip. I
use the hv5122 and 5 which operate quite the
Some of the early scopes only wrote to floppy

I'm not sure what's going on there, looks like maybe a shared ground isn't
connected right? I hope your HV5522 isn't messed up somehow.
That's a digital scope, you should be able to get a screen dump out of it. I
do that with mine:

Hi,
I was following up on a discussion elsewhere which mention the HV5530 as a
control chip for Nixie tubes. This has 32 outputs and 12V digital control, so
it has some drawbacks. There are many other similar chips, in particular the
HV3418, which has 64 outputs at 180V and 5mA, with 5V
