[:SENSe]:DDEMod:LENGth(?)

Sets or queries the range for the digital modulation analysis (see Figure 2--20).

NOTE

. The [:SENSe]:DDEMod:LENGth? query may return a value smaller than

the default (1536) since the value is limited by the number of data points in the
block.

[:SENSe]:DDEMod:LENGth <value>

[:SENSe]:DDEMod:LENGth?

specifies the analysis range by the number of data points.

Range: 1 to [1024

(block size)] or [8192--512=7680] whichever smaller.

To set the block size, use the [:SENSe]:BSIZe command.

DEMDDEM

:SENSe:DDEMod:LENGth 1000

sets the measurement range to 1000 points.

[:SENSe]:BSIZe
