:MEASure:DELay

(see page 798)

Command Syntax

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

<source1>, <source2> ::= {CHANnel<n> | FUNCtion | MATH | WMEMory<r>}

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

<r> ::= 1-2 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 set by the :MEASure:DEFine command

Query Syntax

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

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

source2. The delay measurement is made from the user-defined slope and edge

count of the signal connected to source1, to the defined slope and edge count of

the signal connected to source2. Delay measurement slope and edge parameters

are selected using the :MEASure:DEFine command.

Also in the :MEASure:DEFine command, you can set upper, middle, and lower

threshold values. It is the middle threshold value that is used when performing the

delay query. The standard upper, middle, and lower measurement thresholds are

NOTE

The :MEASure:DELay command and the front-panel delay measurement differ from the

:MEASure:DELay? query.

The delay command or front-panel measurement run the delay measurement in auto-edge

select mode. In this mode, you can select the edge polarity, but the instrument will select the

edges that will make the best possible delay measurement. The source1 edge chosen will be

the edge that meets the polarity specified and is closest to the trigger reference point. The

source2 edge selected will be that edge of the specified polarity that gives the first of the

following criteria:

•

The smallest positive delay value that is less than source1 period.

• The smallest negative delay that is less than source1 period.

• The smallest absolute value of delay.

The :MEASure:DELay? query will make the measurement using the edges specified by the

:MEASure:DEFine command.
