delay, and the last value is sampled at +41.48 mm opti-
cal path delay. When
FAST
measurement update is
selected, the first data value is sampled at +20.74 mm
optical path delay, and the last value is sampled at
–20.74 mm optical path delay. The data value that cor-
responds to zero optical path delay is approximately,
but not exactly, located in the center of the time domain
data.
If your program is aborted or interrupted after sending
this query, the Agilent 86121A continues to process the
data but does not place it in the output buffer. Because
of the amount of data processed, the instrument
will
not respond
to any new commands in its input buffer
for 30 or 40 seconds
.

Notice that only values are returned to the computer.
There is no first value that indicates the number of val-
ues contained in the string as there is, for example, with
the FETCh, READ, and MEASure commands.
