Introduction

:TRACe Subsystem

This subsystem provides access to the scale and offset values.

The :TRACe subsystem used in conjunction with the :CALCulate[1] subsystem, scales and offsets measurement results.

:TRACe:CATalog?

Queries list of intrinsic constants. The Counter has two constants, scale and offset.

Query Response A comma-separated list of strings: “SCALE”, “OFFSET”

:TRACe[:DATA]

OFFSET,

<numeric_value> [HZ S DEG]

 

or

 

:TRACe[:DATA]

OFFSET,

<arbitrary block>

:TRACe[:DATA]?

OFFSET

 

<numeric_value> Range

<numeric_value> Resolution

Query Response

Sets or queries the offset value.

-9.9999990000E+12 to -1.0000000000E-13, 0.0000000000, +1.0000000000E- 13 to +9.9999990000E+12.

11 digits

∙Response will be formatted according to :FORMat[:DATA] ASCii REAL setting.

∙When ASCii format is used, the numeric data is transferred as ASCII bytes in <NR3> format with eleven significant digits.

Comments ∙ *RST: 0.0000000000

∙Updating the offset causes the limit counts (:CALC2:LIM:FCO, :CALC2:LIM:PCO) to be cleared.

∙The front panel menu item is not always able to display all of the significant digits of this value. When this is the case, the displayed value is different from the actual value in that the displayed value has been rounded. However, using the front panel Enter key, while this value is in the 11-digit display, will update the actual value to the displayed (rounded) value.
