Remarks:
The attenuator consists of fixed attenuator and variable attenuator. The
attenuation of the fixed attenuator is 20 dB, and the attenuation range of the
variable attenuator is from 0 dB to 30 dB. Therefore, the input attenuation
ranges f rom 0 dB to 50 dB.

Detector Type
Sets the detector for the current measurement. The selected detector can be applied
to the selected trace. The available trace detectors include Pos P eak, Neg Peak,
Normal, Sam pl e , Average (RMS), and Average (Vol).
1. Pos Peak
For each tr a ce point , P ositi ve P eak detecto r dis plays t he maximum v alue o f data
sampled within the corresponding time interval.
2. Neg Peak
For each trace point, Negative Peak detector displays the minimum value of data
sampled within the corresponding time interval.
3. Normal
Normal detector (also called Rosenfell detector) displays the maximum value
and the minimum value of the sample data segment in alternating sequence.
That is, for an odd-numbered data point, the minimu m val ue of the sample data
is displayed; for an even-numbered data point, the maximum value of the
sample data is displayed. I n this way, the amplitude variation range of the signa l
is clearly shown.
4. Sample
For each trace point, sample detector displays the transient level c or resp on ding

7. Quasi Peak (Option)
Quasi-peak detection is a weighted form of peak detection. For each dat a poi nt,
the detector detects the peak in the corresponding time interval, and uses
quasi-peak detector circuit (containing specific charge and discharge structure)
and the time constants specified in CISPR Publication 16 to make weighted
calculation to display the weighted results. The quasi-peak detection is used for
EMC test.
Note: The charge tim e fo r the quasi-detector is much shorter than the
discharge time, which can not only reflects the amplitude of the signal, but also
the time distribution of the signal.

Math Function
Trace math functions perform mathematical operations between traces
and, in some cases, use r -defined offsets.
1. Op1-Op2
Calculates the power diff eren ce betw een O per and 1 (O p1) a nd Ope ran d 2 (Op2 ),
and saves it to the destination trace. D urin g t he sw eep, the following formula is
executed for each point:
(2-10)
In the above formula, the parameter unit is dB. If a point in Op1 is a maximum
trace value, the difference (the result of the subtraction) is also a maximum
trace value; if the difference is less than or equal to 0, the resultant point is the
minimum trace value.
2. Op1+Op2
Calculates the power sum between Operand 1 (O p1) a nd O perand 2 (Op2), an d
saves it to the destination trace. During the sweep, the following formula is
executed for each point:
(2-11)
In the above for mula, the parameter unit is dB. If a point in Op1 or Op2 is a
maximum trace value, the sum (the result of addition) is also a maximum trace
value.
3. Op1+Offset
Calculates the sum betwe en Opera nd 1 (Op1) a nd the offset, an d saves it to the
destination trace. During the sweep, the following formula is executed for each
point:
(2-12)
In the above formula, the parameter unit is dB.
4. Op1-Offset
Calculates the difference betwee n Operand 1 (O p1) and the offset (Offset), and
saves it to the destination trace. During the sweep, the following formula is
executed for each point:

2. Avg Mode
The average modes include "Log", "RMS", and "Scalar".
Log: In this mode, all filtering and averaging processes select the log unit
(dB). This average type is the most effective one for finding the low-level
signal that is close to the noise amplitude. The formula is shown as follow:
(2-15)
In the above formula, the parameter unit is dB.
RMS: In this mode, all filtering and averaging proce sses work on the power
(the square of the amplitud e) of the signal. This average type is best for
measuring the true time average power of complex signals. The formula is
shown as follows:
(2-16)
In the above formula, the parameter unit is dB.
Scalar: In this mode, all filtering and averaging processes work on the
voltage envelope of the signal. This average type is the most appropriate
one for observing the great enve lope fluctuations of AM or pulse-modulated
signals such as radar and TDMA transm itters. The formula is shown as
