Reply from Hans Foerster:
attached are the files observe.incl and switchf1f2.hf.
Please look into the manual page A-59 for the parameter obschan.
(in older XWinNMR manual (95/3) this is p. 176 - I.M.)
The following parameters must be set:
swh, RG to digitise both spectra with the same parameters.
The pulse program can be rewritten as to use different receiver
and pulse phase cycles for both measurements.
Both channels must be set up in EDASP with preamps assigned.
For 2 channels, nbl must be set to 2 and a 2d file must be used
for acquisition.
with best regards
