Measure Commands 25
Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference 697
:MEASure:THResholds:SERial:TOPBase:ABSolute
Command :MEASure:TOPBase:THResholds:SERial:ABSolute <source>,<top_volts>,<base_v
olts>
The :MEASure:TOPBase:THResholds:SERial:ABSolute command sets the top
level and base level voltages that are used for protocol decode.
<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.
<top_volts>
<base_volts>
A real number specifying voltage levels. The top voltage level must be
greater than the base voltage level.
Example This example sets the voltage level for the top to 0.9 volts and the voltage
level for the base to 0.1 volts on channel 2.

Query :MEASure:THResholds:SERial:TOPBase:ABSolute? <source>
The :MEASure:THResholds:SERial:TOPBase:ABSolute? query returns the
current settings for top level and base level voltages.
