Amplifier problem

Amplifier problem

Hi.We have a 500 MHz AVANCE-DRX spectrometer and I have a question about it .How we can understand that the amplifier has been weakened?

[Question from NMRWiki Q&A forum] Amplifier Error Amplifier Error Hi All, I am worikng with 500Mhz Bruker. Recently 3rd channel is installed in my institute when i run 3D HNCA experiment with t2 increments (64)for higher resolution. I warned with an amplifier error message and stops experiments. Can anyone help in this regards. Thank you in advance. Check if somebody has answered this question on NMRWiki QA forum	nmrlearner	News from other NMR forums	0	09-27-2012 03:39 AM

[Question from NMRWiki Q&A forum] How do you build an NMR power amplifier? How do you build an NMR power amplifier? And how to you match it to the NMR coil? Basically I'm looking to perform NMR experiments with frequencies in the 500KHZ region. I already have an arbitrary function generator that I can program with the required pulses at that frequency, now I need to amplifier the signal, and deliver the current to a coil. How do build an amplifier that can drive a lot of current into a coil at that frequency? Do I resonate the coil with a capacitor, and if so, how do I ensure the resulting circuit won't ring, and ruin the pulse sequences? ...	nmrlearner	News from other NMR forums	0	11-24-2011 02:49 PM

[Question from NMRWiki Q&A forum] dmf problem in vnmr dmf problem in vnmr Hi, dear all, I try to use garp1 sequence for decoupling with the statement " obsprgon("garp1", pw, angle, 0) ". If angle = 1.0, when pw = 4us or larger than 4us, the sequence works. When pw less that 4us, it shows the error "effective dmf too high prg dec on on controller dec". If angle = 2.0, when pw = 2us or larger than 2us, it works. When pw less that 2us, the it shows the same error message.	nmrlearner	News from other NMR forums	0	06-27-2011 04:31 PM
[Question from NMRWiki Q&A forum] Why RF irradiation will damage amplifier? Why RF irradiation will damage amplifier? Here our 1H amplifier of NMR spectrometer is damaged twice for long time or high power RF irradiation. Why the duty cycle is important for amplifier or probe?If the damage happens to amplifier, which part of it is broken? edit: The type of our spectrometer is Varian InfinityPlus for solids bought in 2003. I have no idea about the sort of amplifiers, just know the amplifier is for power output. Someone used about 80kHz 1H power for 1H decoupling during 100-200ms acquisition. The efficiency of the amplifier output droped gradually. The efficiency...	nmrlearner	News from other NMR forums	0	09-28-2010 10:03 PM
