Hi all,
I'd like to know whether you think an oscilloscope is a useful tool
for troubleshooting modern high-field digital spectrometers.
I'm performing my due diligence for my new lab, which currently does
not have a scope with sufficiently high frequency for our systems. We
are considering purchasing a scope that not only meets our current
needs (systems up to 600 MHz), but will also meet the needs we aspire
to have in the future (900 MHz, for the sake of argument).
I found my old 1 GHz scope to be very valuable for troubleshooting
older 600 MHz Inovas, but we haven't yet had to do much RF
troubleshooting for our relatively new Avance-III and VNMRS consoles.
I don't want to be in the position of buying a $30K 2.5 GHz scope
today, only to find years from now when our Inovas are all retired
that the digital consoles aren't amenable to being probed by
oscilloscopes.
If you have digital consoles that you need to troubleshoot, please let
me know whether you find oscilloscopes of appropriately high frequency
(~2X spectrometer frequency and above) are useful for you, or whether
you've found you do not need one.
Thanks.
- Josh
