·[Auto] : The mode will be standard automatically by default after the detection menu is
entered.
·[Normal] : In this mode, the measuring results of positive peak and negative peak will
be displayed to realize the display effect similar to the analog instrument when noise is
detected, and only positive peak will be displayed when a signal is detected. This is the
most commonly used detection mode, in which the signal and noise floor can be seen
simultaneously without loss of any signal.
·[Peak] : It is used to select the positive peak detection mode. The enabling of this
mode can ensure that no peak signal is missed, which helps to measure the signal very
close to the noise floor. The positive peak detector is selected in case of [Max Hold].
·[Neg Peak] : It is used to select the negative peak detection mode. The enabling of this
mode allows the trace to display the negative peak level. This mode is used in the self
test of broadband millimeter-wave spectrum analyzer in most cases, while seldom in
measurement. It can reproduce the modulation envelope of AM signal well. The
negative peak detector is selected in case of [Min Hold].
·[Sample] : It is used to set the detector as the sampling detection mode. This mode
helps to measure the noise signal, and it allows better measurement of noise compared
with the normal detection mode. It is commonly used for the video average and noise
frequency standard functions.
·[Average] : It is used to set the detector as the average detection mode, in which the
average of sampling data of traces will be displayed in each sampling interval.
·[RMS] : It is used to set the detector as the root mean square detection mode, in which
the root mean square of sampling data of traces will be displayed in each sampling
interval.
·[Back] : It is used to return to the previous menu.
