1.7 Basic Measurement

In this section, we introduce how to use the analyzer to do basic me a surements. Considering a 50 MHz, 0dBm sine wave signal produced from a generator (such as RIGOL DG3101A).
CAUTION
The signal amplitude must be less than 30 dBm (equal to 1 W), when its frequency range is from 10 MHz to 3 GHz, or else it will switch the input to a high power impedance state, and consequently the signal cannot be measured by the instrument.
Procedures:
1. Power on
2. Reset to factory settings

2.1 Basic Settings

2.1.1 FREQ

Sets the frequency parameters of the analyzer. The analyzer sweeps within a specified frequency range, and the sweep is restarted every time you change this parameter.
The frequency range of a channel can be expressed by either of two groups of parameters: Start Fr equency and Stop Frequency; or Center Frequency and Span. If any such p ar ameter is c hanged, the others would be adjusted automatically in order to ensure the coupling relationship among them.
(Equation 2-1)
(Equation 2-2)
,
,
and
denotes the center f requency, the stop frequency, the
start fr equency and the span respectively.
2.1.1.1 Center Freq
Sets the center frequency of the sweep. When pressed, the frequency mo de is switched to Center Freq and Span in order to enter the desired parameter data. In this mode, parameters you specified are always shown at the lower right and left side of the display grid.
Key Points:
The start and stop frequencies vary with the center frequency when the span is
constant.
Changing the center frequency horizontally shifts the current sweep channel and
the adjustment is limited by the specified frequency range.
In Zero Span mode, the start frequency, stop frequency and center frequency are
always equal. If one is changed the others are updated to match.
You can modify this parameter using the numeric keys, knob, or direction keys.
Refer to “Parameter Input” for more details.

2.1.2 SPAN

Sets the span value of the analyzer. The changing of this parameter will affect other parameters associated with the FREQ function, and restart the sweep.
2.1.2.1 Span
Sets the frequency range of the sweep. When pressed, the frequency mode is switched to Center Freq and Span in order to enter the desired parameter data. In this mode, parameters you specified are always shown at the lower left and right sides of the display grid.
Key Points:
The start and stop frequencies are changed with the span automatically. In manual span mode, the span can be set down to 100 Hz (the only way into the
zero-span mode is to press the Zero Span menu option) and up to the full span described in “
Modifying the span in non-zero span mode may cause an automatic change in
both CF st e p and RBW if they were in Auto mode, and the change of RBW may influence VBW (in Auto VBW mode).
In non-zero span mode , variation in the span, RBW or VBW would cause a change
in sweep time.
In non-zero span mode, neither “Video” trigger nor “1/Δtime” readout function is
valid.

2.1.3.5 Scale Type
Sets the Scale Type of Y-axis to Lin or Log, the default is Log.
Key Points:
In Log scale type: the Y-axis denotes the logarithmic coordinates, the value
shown at top of the grid is the reference level and the grid size is equal to the scale value. The unit of Y-axis will be automatically switched into the default “dBm” when the scale type is changed from Lin to Log.
In Lin scal e type: the Y-axis denotes the linear coordinates, the value shown at
the top of the grid is the reference level and the bottom of the grid shows 0 V. The grid size is 10% of the Reference level and the Scale/Div is invalid. The unit of Y-axis will be automatically switched into the default “Volts” when the scale type is changed from Log to Lin.
Other than as mentioned above, the unit of Y-axis is independent of the Scale
Type.
2.1.3.6 Units
Sets the unit of the Y-axis to dBm, dBmV, dBuV, Volts or Watts. The units dBm, dBmV, and dBuV are for Log scaling; Volts and Watts are for Linear scaling. The default is dBm.

2.2.2.1 Time
Sets the time interval for t he analyzer to complete a sweep. Either Auto or Manual can be used, the default is Auto.
Key Points:
In non-zero span, the analyzer uses the shortest sweep time on the basis of the
current RBW and VBW settings if Auto is selected.
Decreasing the sweep time would sp eed the measurement. However, an error
may be caused if the specified time is less than the minimum duration in Auto coupli ng, and “UNCAL” is shown at the status bar of the screen.
You can modify this parameter using the numeric keys, knob, or direction k ey s .
For more details, please refer to “Parameter Input”.

Parameter
Explanation
Hint
Key Points:
Changing the points ma y influence the sweep time which is limited by the sa mple
rate of the ADC (Analog to Digital Converter). That is, the more points used, th e longer the sweep will be.
Changing the points would also influence other system parameters, thus the
instrument restarts the sweep and measurement cycle.
You can modify this parameter using the numeric keys, knob or dire ct i on keys.
For more details, please refer to “Parameter Input”.

The sweep points will automatically change to the maximu m (3001) and the
menu is grayed out and disabled in Video trigger type.
With the increase (more than 601) of sweep points, the frequency resolution of
marker point s increases and the sweep speed decreases.
In additi on to the sweep points, other parameters such as span, resolut i on
bandwidth, video bandwidth, average detection method, and center frequency can also influence the sweep speed.
