"Termination" of the trigger signal RF cable
Terminate the trigger line with 50
ohms at one switch unit. To do so, terminate it
either at the primary switch unit (in the absence of secondary switch units) or typi-
cally at the last secondary switch unit (if available). Termination can be
internal
inside a switch unit as in
or
external
.
–
For the standard case with
internal
termination, consider a setup as follows:
Figure 5-48: Schematic trigger setup with internal 50
ohms termination in the last switch
unit (3)
1 = Source of the trigger signal, for example a signal generator
2 = Primary switch unit
3 = Secondary switch units
4 = T-junctions in the trigger signal RF cables (blue lines)
5 = Internal 50 ohms termination
If the signal cable is not externally terminated (as in
), use internal
termination in
one
switch unit. To do so, set "Termination" to "50 Ohm" in
this
switch unit and to "High Impedance" in
all other
switch units.
–
For the alternative case with
external
termination, consider a setup as follows:
Figure 5-49: Schematic trigger setup with external 50
ohms termination (5) after the last trig-
ger input
1 = Source of the trigger signal, for example a signal generator
2 = Primary switch unit
3 = Secondary switch units
4 = T-junctions in the trigger signal RF cables (blue lines)
5 = External 50 ohms termination
If the external 50
ohms termination (labeled 5 in
"Termination" to "High Impedance" in
all
switch units.
Make sure to
avoid
simultaneous internal and external termination.
