Measure Commands 25
Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference 699
:MEASure:THResholds:SERial:TOPBase:METHod
Command :MEASure:THResholds:SERial:TOPBase:METHod <source>,{ABSolute | HISTONLY
| MINmax | STANdard}
The :MEASure:THResholds:SERial:TOPBase:METHod command determines
the way that the top and base of a waveform are derived 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.
Example This example sets the method used to derive the top and base of a
waveform to the histogram method.

Query :MEASure:THResholds:SERial:TOPBase:METHod?
The :MEASure:THResholds:SERial:TOPBase:METHod? query returns the
current method being used to calculate the top and base of a waveform.
Returned Format
[:MEASure:THResholds:SERial:TOPBase:METHod] {ABSolute | HISTONLY | MINma
x | STANdard}
Example This example returns the method used to derive the top and base of a
waveform for channel 1.
NOTE
These serial threshold settings are used for protocol decode.
