VBW varies with RBW when it is set to Auto. While in Manual mode, VBW is
not affected by RBW.
You can modify this parameter using the numeric keys, knob or direction keys.
For more details, please refer to "Parameter Setting".
V/R Ratio
Set the ratio of VBW to RBW.
Key Points:
This value is different while measuring different kinds of signals:
Sine signal: use 1 to 3 (for faster sweeps)
Pulse signal: use 10 (to reduce the influence on the amplitude of transient
signals)
Noise signal: generally use 0.1 (to obtain the average of noises)
You can modify this parameter using the numeric keys, knob or direction keys.
For more details, please refer to "Parameter Setting".
Detector Type
The analyzer displays the sweeped signal on the screen in the form of trace.
For each trace point, the analyzer always captures all the data within a specific
time interval and processes (Peak, Average,etc.) the captuered data using the
detector currently selected, then display the processed data (one point) on the
screen .
Key Points:
Select an appropriate detector type according to the actual application in
order to ensure the accuracy of the measurement.
The available types are Pos Peak, Neg Peak, Sample, Normal, RMS Avg,
Voltage Avg and Quasi-Peak. The default is Pos Peak.
The corresponding icon (as shown in the figure below) of the detector type
selected is displayed in the status bar at the left side of the screen.
