Operation
used, i.e. when function parameters are changed. Pos-
sible alarms occuring during instrument operation
(setting of functions) are to be ignored.
Display of gates
To make the assignment easier, the gates are displayed
in different colors. You cannot vary the colors of gates
because they are fixed as follows:
• Gate A – red
• Gate B – green
• Gate C – blue
aLOGIC/bLOGIC
(Evaluation logic of the gates)
This function allows you to choose the method for trig-
gering the gate alarm. The alarm is output to the LED
A
on the front panel of the USM 35X. There are four set-
ting options available:
Setting the gates (function groups aGAT and bGAT)
• off – Evaluation logic off
The alarm and measurement capability are switched
off. The gate is not visible.
• pos – Coincidence
The alarm (LED A) is on if the preset response
threshold of the gate is exceeded within the dis-
played range.
• neg – Anticoincidence
The alarm (LED A) is on if the preset response
threshold of the gate is not reached within the
displayed range.
• a trig – Triggering by interface echo
When using gate A as echo-start gate (setting of the
evaluation logic for gate B)
– Select the function aLOGIC or bLOGIC .
– Set the required alarm logic by means of the right-
hand rotary knob.

Note:
The alarm and measurement function of the gates is
only active within the display range.
