:WAVeform:PREamble? has all of them combined with extra information as well.
i dont think it helps. it doesnt have XORigin or XREFerence relative to the other channels. for example XREF ch1 relative to ch2, or another value relative to ch3 etc. for example in my case here, preamble is...
0,1,300,1,2.000000e-09,-3.000000e-07,0,4.281250e-02,0,118 for SOUR:CHAN1 and..
0,1,300,1,2.000000e-09,-3.000000e-07,0,4.230469e-02,-47,120 for SOUR:CHAN2
the difference is in YORi and YREF which is not the above problem (x-axis phase shift) so lets forget Y data. and i dont know what XREF and XORi refering or relative to what? i have -3.000000e-07 XORigin, its -300ns, so i doesnt make sense since time offset in the above picture is 120ns, XREF is useless, its 0. even if i manage to find offset ch1 data in relative to ch2 data. to correctly show them on screen, i have to x-offset either one resulting in... not so nice figure...
