OFFSET, <numeric_value> [HZ | S | DEG]
or
OFFSET, <arbitrary block>
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.
*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.
