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] 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
