The following program segment shows how to use TTL output 1 to
indicate when a measurement is outside the range -30 dBm to -10 dBm. It
is assumed that the measurement has already been set up in the upper
window (window 1).
CALC1:LIM:LOW -30 Sets the lower limit for the upper
window to -30 dBm.
CALC1:LIM:UPP -10 Sets the upper limit for the
upper window to -10 dBm.
CALC1:LIM:STAT ON Turns the limits on.
OUTP:TTL1:FEED
“CALC1:LIM:LOW,CALC1:LIM:UPP”
Specifies that TTL output 1
should be asserted when the
upper or lower limit fails on the
upper window.
OUTP:TTL1:ACT HIGH Specifies that TTL output 1
should be active-high.
OUTP:TTL1:STAT ON Activates TTL output 1
