24 :MEASure Commands

:MEASure:DELay

(see page 1610)

Command Syntax

:MEASure:DELay [<edge_select_mode>][,][<source1>][,<source2>]

<edge_select_mode> ::= {MANual | AUTO}

<source1>, <source2> ::= {CHANnel<n> | FUNCtion<m> | MATH<m>

| WMEMory<r> | <digital channels>}

<n> ::= 1 to (# analog channels) in NR1 format

<m> ::= 1 to (# math functions) in NR1 format

<r> ::= 1 to (# ref waveforms) in NR1 format

<digital channels> ::= DIGital<d> for the MSO models

<d> ::= 0 to (# digital channels - 1) in NR1 format

The :MEASure:DELay command places the instrument in the continuous

measurement mode and starts a delay measurement.

The measurement is taken as:

delay = t(<edge_spec_2>) - t(<edge_spec_1>)

where the <edge_spec> definitions are determined by the <edge_select_mode>

and the :MEASure:DELay:DEFine command.

When the <edge_select_mode> is:

• AUTO — edges are automatically selected: the source1 edge closest to the

timebase reference point is used, and the source2 edge closest to the source1

edge is used.

• MANual — edge numbers are determined by the :MEASure:DELay:DEFine

settings.

Edge numbers greater than zero (0) are counted from the left side of the display

for both sources.

Edge slopes are always determined by the :MEASure:DELay:DEFine settings.

If the <edge_select_mode> is not included with the command, AUTO is the default.

Query Syntax

:MEASure:DELay? [<edge_select_mode>][,][<source1>][,<source2>]

The :MEASure:DELay? query measures and returns the delay between source1 and

source2. Delay measurement slope and edge count parameters are determined by

the <edge_select_mode> and the :MEASure:DELay:DEFine command.

The <edge_select_mode> definitions are the same as with the command syntax.

However, if the <edge_select_mode> is not included with the query, MANual is the

default.
