Detector
】
While displaying a wider span, each pixel contains spectrum
information associated with a larger subrange. That is, several
samples may fall on one pixel. Which of the samples will be
represented by the pixel depends on the selected detector type.
Press this key to pop out the relevant menu includes
[Auto],[Normal],[Pos Peak],[Neg Peak],[Sample].
Key points:
 Selects an appropriate type according to the application in order
to ensure the accuracy of the measurement for your application.
 The available types are: Pos Peak, Neg Peak, Sample.

Every selected type is shown with a parameter icon on the left
status bar of screen.

Type
Measurement
Auto
Normal wave detect is the most common way
to detect waveform. It can observe the signal
and base noise at the same time without
loosing any signal.
Normal
Display pos peak and neg peak alternately
when noise is detected, or it only display pos
peak.
Pos Peak
Positive peak detection ensures that no peak
signal is missed, which is useful for measuring
signals that are very close to the base noise.
Neg Peak
Negative peak detection is used in most cases
with the self-test of the spectrum analyzer and
is rarely used in the measurement. It is able to
restore the modulation envelope of the AM
signal well.
