Appendix B: Wa veform Data in MSO/DPO2000B and MSO/DPO2000 Series Instruments
COMPOSITE_YT
COMPOSITE_YT, COMPOSITE_ENV
SINGULAR_YT
The composition of the waveform data to be queried using the
CURVe?orWAVF r m ? queries is set using the DATa:COMPosition or
WFMOutpre:COMPosition command. The compositions which can be set are:
COMPOSITE_YT
COMPOSITE_ENV
SINGULAR_YT
If the composition set is not available w ith the current acquisition and horizontal
settings, no response is returned for the CURVe?orWAVFrm? query and a n
event is set.
For example, if
COMPOSITE_ENV data is not available and a CURVe?queryis
sent with the composition set to
COMPOSITE_ENV, no data will be returned and an
error event is set:
> :DATA :COMPOSITION:AVA ILABLE?
COMPOSITE_YT
> DATA: COMPOSITION?
COMPOSITE_YT
> DATA: COMPOSITION
COMPOSITE_ENV
> *ESR? 0 > CURVE? {no data returned}
> *ESR?

> EVMSG ?
221,"Settings conflict; Envelope waveform not available;
CURVE?" >
The composition of the waveform data to be sent to the instrument for transfer
to the reference waveform memory using the CURVe command is set using the
WFMInpre:COMPosition command. The compositions which can be set are:
COMPOSITE_YT
COMPOSITE_ENV
SINGULAR_YT
Filtering of Waveform Data
with FilterVu
The FilterVu feature uses digital signal processing (DSP) techniques to apply low
pass filtering to the acquired waveform data for the analog channels. The FilterVu
feature provides fi ltering of the displayed waveform so that you can see your
signal without the effects of noise. This is the reduced re solution waveform. A
side effect of filtering the reduced resolution waveform is that t he full resolution
waveform may be subjected to filtering to achieve the desired filtering of the
