BUS:UPPerthreshold{:MATH|:MATH1} {<NR3>|ECL|TTL }
BUS:UPPerthreshold{:MATH|:MATH1}?
Related Commands
BUS:LOWerthreshold{:MATH|:MATH1}
Arguments
<NR3> is a floating point number that specifies the upper threshold of the math
waveform, in volts.
ECL – ECL (-1.3 volts). Note that this setting is constrained, depending upon the
vertical scale for the specified math waveform.
TTL – TTL (1.4 volts). Note that this setting is constrained, depending upon the
vertical scale for the specified math waveform.
Examples
BUS:UPPerhreshold:MATH TTL sets the upper threshold for the math
waveform to 1.4000 volts.
BUS:UPPerhreshold:MATH? might return 0.0E+0, which is the default.
BUS:UPPerthreshold:REF<x>
This command sets the upper threshold for each reference waveform. This applies
to all search and trigger types that use that reference waveform.
