Specific Commands

In ASCii format, the numeric data is transferred

to ASCii bytes in <NR1 NUMERIC RESPONSE

DATA>, <NR2 NUMERIC RESPONSE DATA> or

<NR3 NUMERIC RESPONSE DATA>

representation, as appropriate.

In PACKed format, data is transferred to a

<DEFINITE BLOCK RESPONSE DATA>, in a

manner specified in the device documentation.

 Length:

The program data syntax for <Length> is

defined as a <DECIMAL NUMERIC PROGRAM

DATA> element.

When ASCii data format is selected, the optional

<Length> parameter specifies the number of

significant digits to be returned. A <Length>

value of zero indicates that the device selects the

number of significant digits to be returned. When

a <Length> of zero has been specified, the

FORMat[:DATA]? query returns zero as its second

parameter.

When the PACKed data format is selected, the

optional parameter <Length> it not used.
