Figure 3.40. Example of a 600 WB NMR Instrument Site
The example of a 600 WB NMR instrument site in the figure above provides easy
access to the probe from either side.
EDASP Display: Software Controlled Routing 3.9
The menu edasp shows all relevant RF routing and allows the routing which are
under software control to be changed. The following restrictions apply:
•
Connections between transmitter and preamplifier cannot be changed (the
command
edasp setpreamp with NMR Super user permissions does that).
•
Channel F1 is the detection channel by default (which is no limitation).
•
Detection must usually be routed via the same SGU as the F1 pulses are,
since that SGU will supply the phase coherent reference signal. In some cas-
es, pulsing and detection may use different SGU’s, but provisions must be
made to add the signal up coherently (using exactly the same frequency on
both channels is usually coherent).
•
Routing between SGU's and transmitters can only be selected if cf (the config-
uration routine) has found a hardware connection that supports this routing.
•
Most routine applications will route correctly if the “default” button is pressed in
the short menu version (receiver routing not shown).
