DETECTOR
MAX PEAK
The
DETECTOR MAX PEAK
softkey activates the max peak detector. It is recom-
mended for measurement of impulsive signals.
Remote command:
DET POS
DETECTOR
MIN PEAK
The
DETECTOR MIN PEAK
softkey activates the min peak detector. Weak sine-
wave signals become clearly visible in noise using this detector. In case of a com-
posite signal made up of sinewave and impulsive signals, the impulsive signals are
suppressed.
Remote command:
DET NEG
DETECTOR
SAMPLE
The
DETECTOR SAMPLE
softkey activates the sample detector.
It is used for measuring uncorrelated signals such as noise. The power can be
determined with the aid of fixed correction factors for evaluation and the logarithmic
function.
Remote command:
DET SAMP
DETECTOR
RMS
The
DETECTOR RMS
softkey activates the rms detector.
The rms detector supplies the power of the signal independent of the waveform. For
this effect the root mean square of all sampled level values is formed during the
sweep of a pixel. The sweep time thus determines the number of averaged values
and with increasing sweep time better averaging is obtained. The rms detector is
thus an alternative for averaging over several sweeps (see TRACE AVERAGE).
Since the video bandwidth must be at least 10 times the resolution bandwidth
(RBW) to ensure that video filtering does not invalidate the rms values of the signal,
this ratio is set automatically upon activating the detector.
Remote command:
DET RMS
DETECTOR
AVERAGE
The
DETECTOR AVERAGE
softkey activates the average detector.
In contrast to the rms detector, the average detector supplies the linear average of
all sampled level values during the sweep of a pixel.
The same relations as for the rms detector apply (see above).
Remote command:
DET AVER
DETECTOR
QPK
The
DETECTOR QPK
softkey activates the quasipeak detector.
This detector evaluates the sampled level values during the sweep of a pixel like an
analog voltmeter.
On switching the quasipeak detector on the video bandwidth is automatically set to
10*RBW so as to exclude the influence of the video filter on the signal evaluation.
Remote command:
DET QPE
With an active quasipeak detector only the resolution bandwidths 200 Hz, 9 kHz
and 120 kHz are available..
