34 :WAVeform Commands

:WAVeform:PREamble

(see page 1276)

Query Syntax

:WAVeform:PREamble?

The :WAVeform:PREamble query requests the preamble information for the

selected waveform source. The preamble data contains information concerning

the vertical and horizontal scaling of the data of the corresponding channel.

Return Format

<preamble_block><NL>

<preamble_block> ::= <format 16-bit NR1>,

<type 16-bit NR1>,

<points 32-bit NR1>,

<count 32-bit NR1>,

<xincrement 64-bit floating point NR3>,

<xorigin 64-bit floating point NR3>,

<xreference 32-bit NR1>,

<yincrement 32-bit floating point NR3>,

<yorigin 32-bit floating point NR3>,

<format> ::= 0 for BYTE format, 1 for WORD format, 4 for ASCii format;

an integer in NR1 format (format set by :WAVeform:FORMat).

<type> ::= 3 for HRESolution type, 2 for AVERage type, 0 for NORMal

type, 1 for PEAK detect type; an integer in NR1 format

(type set by :ACQuire:TYPE).

<count> ::= Average count or 1 if PEAK or NORMal; an integer in NR1

format (count set by :ACQuire:COUNt).

Y origin (V)

Y increment =

voltage of 1 Vstep

Y reference = #Vsteps / 2

X origin (t)

X increment (t) = time between successive points

X reference = 0

Delay = (#points / 2) * Xincrement + Xorig

Offset

#Vsteps =

65536 (if format = WORD)

256 (if format = BYTE)
