Measured values, identical to spectrum data:
<x value>, <y1>, <y2>; <y2> being available only with detector
AUTOPEAK and containing in this case the smallest of the two
measured values for a measurement point.

7.14 Optimizing Measurements
7.14.1 Minimizing the Measurement Duration
If you want to minimize the measurement duration, try the following methods to opti-
mize the measurement:
●
Reduce the span of the measurement to the relevant parts of the signal only.
