Commands Listed in Alphabetical Order
MORETHAN trigg
ers the oscilloscope when the input pattern is true
for a time period more (greater) than the time period specified in
TRIGGER:A:LOGIC:PATTERN:DELTATIME.
EQUAL triggers the oscilloscope when the input pattern is true for a time period
equal to the time period specified in
TRIGGER:A:LOGIC:PATTERN:DELTATIME,
within a ±5% tolerance.
UNEQUAL triggers the oscilloscope when the input pattern is true for a time
period greater than or less than (not equal to) the time period specified in
TRIGGER:A:LOGIC:PATTERN:DELTATIME, within a ±5% tolerance.
Examples
TRIGGER:A:LOGIC:PATTERN:WHEN LESSTHAN sets the oscilloscope to trigger
when the pattern is true for a time period less than the pattern trigger delt
a time
setting.
TRIGger:A:LOGIc:THReshold:CH<x>
This command sets or queries the trigger A logic threshold voltage for the
specified channel x.
Group
Trigger
Syntax
TRIGger:A:LOGIc:THReshold:CH<x> {<NR3>|ECL|TTL}
TRIGger:A:LOGIc:THReshold:CH<x>?
Arguments
<NR3> is a floating point number that specifies the threshold voltage, in volts.
ECL specifies a preset ECL high level of –1.3V.
TTL specifies a preset TTL high level of 1.4V.
Examples
TRIGGER:A:LOGIC:THRESHOLD:CH2 3.0E-3 sets the A logic trigger threshold
voltageforChannel2to3mV.
TRIGGER:A:LOGIC:THRESHOLD:CH3? might return
:TRIGGER:A:LOGIC:THRESHOLD:CH3 1.2000E+00, indicating that the A
logic trigger threshold voltage for Channel 3 is 1.2 V.
TRIGger:A:LOGIc:THReshold:D<x>
This command specifies the trigger A logic threshold level for the specified digital
channel <x>. This commands affects all trigger types using the digital channel.
