Measure Commands

:MEASure:THResholds:HYSTeresis

Command
:MEASure:THResholds:HYSTeresis <source>,<range>,<level>
The :MEASure:THResholds:HYSTeresis command sets the range and level
voltages that are used to calculate the measurements that use them. The
range is added to the level to determine the upper level voltage for
measurements that use it. The range is subtracted from the level to
determine the lower level voltage. The level is the middle level voltage.
<source> {ALL | CHANnel<N> | FUNCtion<F> | DIGital<M> | WMEMory<N> |
CLOCk | MTRend | MSPectrum | EQUalized}
MTRend and MSPectrum sources are only available if the oscilloscope has
the EZJIT option installed and the feature is enabled.
The CLOCk source is only available if the oscilloscope has the High Speed
Serial option installed and the feature is enabled.
The EQUalized source is only available if the oscilloscope has the High
Speed Serial option and the Serial Data Equalization option installed and
the features are enabled. This command uses the Feed- Forward Equalized
(FFE) signal as the source. Setting the source to ALL does not affect the
individual channel settings which is the behavior as the user interface.
<N> An integer, 1- 4.
<F>
An integer, 1- 16.
<M>
An integer, 0- 15. Digital channels are available on mixed- signal
oscilloscopes.
<range> A real number specifying voltage range for the hysteresis around the level
value.
<level> A real number specifying voltage level.
Example This example sets the hysteresis range to 0.9 volts and 0.1 volts for the
level on channel 2.
myScope.WriteString ":SYSTem:HEADer OFF"
myScope.WriteString ":MEASure:THResholds:HYSTeresis CHANNEL2,0.9,0.1"
Query
:MEASure:THResholds:HYSTeresis? <source>
The :MEASure:THResholds:HYSTeresis? query returns the current settings
for upper level, middle level, and lower level voltages for the custom
thresholds.
Returned Format
[:MEASure:THResholds:HYSTeresis]<range>,<level><NL>
Example This example returns the range and level voltages used to calculate the
measurements on channel 1.
