right = delay 1 ns
The position of the time gate is always relative to the end of the offset transmission
line. As a consequence, "Adjust Time Gate" allows measurements at variable offset but
fixed time gate position.
Example: The impedance of an antenna with possible faults is measured using a time
gate and a variable length offset. If "Adjust Time Gate" is off, the time gate is at a con-
stant distance from the offset-corrected reference plane (end of the offset transmission
line). Its absolute position is varied along with the length offset.
If "Adjust Time Gate" is on, the time gate is moved to left (right) when the offset-correc-
ted reference plane is moved to the right (left). Its absolute position remains fixed. With
this setting, it is possible, e.g., to keep the time gate at the position of the antenna con-
nector while the antenna is measured at different length offsets.
