:DATA?

Command syntax:

:CALCulate2:TRACe:DATA?

Return String Format:

If no readings are in buffer: Empty

If 5 readings are in buffer:

Note: Using GPIB interface, the Return String Format will be different than above in that

<LF> character will not follow after every reading. For example, for 2 readings, the

format will be:

<reading><sp><unit>:<reading><sp><unit>:

Where:

<reading> - This is the stored reading and consists of 8 characters, which includes decimal.

If the reading does not take up 8 characters, the unused characters become spaces.

For example: If the stored reading is 11.0016, the return string is: _ 11.0016

If the stored reading is 0.326, the return string is: _ _ _0.326

(where _ is a space)

<sp> - This is a space character.

<unit> - This is the unit notation that corresponds to the <reading>.

It can be m (10

-3

), u(10

-6

), or n(10

-9

If the <reading> does not require a unit notation, this becomes a <sp>.

For example: 1.234 VDC does not require a unit notation.

<LF> - Linefeed character (0x0A, \n)

Description:

When this command is sent, all the readings stored in the buffer are sent to the computer. If there

are no readings in the buffer, it will return with the string “Empty”.
