Gating Equations
To gate a histogram using the — sign, or to
edit an existing histogram equation:
1.
[Region].
2.
The histogram number above the
histogram you want to gate.
Type the gate equation and press Û.
Sequential Gating
IMPORTANT
incorrect analysis results, if you do not include all the gate regions in the gate equation.
To the right is an example of sequential
gating.
Histogram 2 is gated on region A from
histogram 1.
Since histogram 3 is gated on region B, it
must also have region A in its gate equation
because region B and histogram 2 are gated
on region A.
If histogram 3 had only region B in its gate
equation, the analysis results for histogram 3
would be include events outside of region A.

For a sequentially gated histogram, gating may not work as intended resulting in possible
