Default How to adjust the receiver gain in a deuterium oxide protein sample?

How to adjust the receiver gain in a deuterium oxide protein sample?

I am running a 15N HSQC on a protein sample which is in a 100% deuterium oxide solvent. The command rga in TopSpin gives a value of >10000 for the receiver gain. I understand this is happening because there is no water signal and hence the receiver gain is optimizing the S/N. However, should the experiment be run with that high value or should it be adjusted to a value of a size similar to the one used on water samples?

[Question from NMRWiki Q&A forum] Sensitivity gain by utilizing steady state polarization
Sensitivity gain by utilizing steady state polarization What do we exactly mean by "utilizing steady state polarization" to gain sensitivity in an experiment?...I know that steady state should be achieved before the start of acquisition which means, in a way, it is already being used for 1H,13C/15N(isn't it?)...I am lost in understanding this concept!...also, how/why does it differ in standard pulse sequences and spin state selective coherence transfer experiments?

[U. of Ottawa NMR Facility Blog] Receiver Gain and Signal-to-Noise Ratio
Receiver Gain and Signal-to-Noise Ratio The signal-to-noise ratio in an NMR spectrum can be affected drastically the choice of the receiver gain setting, so care should be taken to set the receiver gain correctly for optimum results. At very low receiver gain settings, both the signal and the noise use only a fraction of the available digitization levels of the analog-to-digital concertor (ADC). As a result, the intensity of each point in the FID is represented with only a few possible values and the FID is "choppy". This is analogous to a black and white photograph being represented...

[Question from NMRWiki Q&A forum] 2DNOESY with N15 C13 Labelled sample or Unlabelled sample
2DNOESY with N15 C13 Labelled sample or Unlabelled sample Dear Friends, I am in process of doing structure calculation of dimeric protein 22kD by using ARIA2.2 . Can I acquire 2DNOESY spectrum for my protein. Will it provide useful information for structure calculation? And whether I should acquire 2DNOESY with N15 C13 Labelled sample or Unlabelled sample . Which sample would be appropriate for this kind of experiment on VNMRJ 700 with biopack ? Thanks & Regards Srinivas Check if somebody has answered this question on NMRWiki QA forum

[Question from NMRWiki Q&A forum] Switiching off the receiver during acquisition
Switiching off the receiver during acquisition Hello nmr wikier. I use Bruker Avance I AQS 400. TopSpin Version 1.3 For a test I want to switch off the receiver during the acquisition. In pursuance of the pulse programming manual I can do that with the statement setrtp. So I wrote following pulse programm (excerpt): 1 ze 2 30m p1 ph1 3 DE1 DE2 DERX DEADC DEPA DE3 4 0.1u DWELL_GEN:f1

Should I decouple deuterium on 2H/15N labeled sample for R1, R2 and hetnoe? If I'm running relaxation experiments (15N) for R1, R2, and hetnoe on a double labeled (2H/15N) sample, do I need to do any deuterium decoupling added to the program?
