Basic operations
Start a measurement:
1. Set the frequency range (STIMULUS→START/STOP or CENTER/SPAN)
2. Calibration (According to actual needs, refer to the next chapter)
3. Select display format and channel (DISPLAY→FORMAT/CHANNEL)
4. Save the parameters for the next measurement. (SAVE→0/1/2/3/4)
You can change the display format and channel selection at any time. In the normal test mode, tap the right
area of the screen or press the multifunctional switch to call up the menu. Tap the screen or turn the
multifunctional switch to select a menu item.
Select the display trace and display format/channel:
The menu DISPLAY → TRACE item can choose to open (activate) or close the corresponding display curve.
When the background color of the curve name is consistent with the curve color, it indicates that the curve is
active. The items FORMAT, SCALE, and CHANNEL are only valid for this curve.
DISPLAY→SCALE can adjust the scale, DISPLAY→CHANNEL can select the measured port.
Setting the frequency range:
The frequency range of a channel can be expressed by three groups of parameters:
Start Frequency, Center Frequency and Stop Frequency. If any of the parameters change, the others will be
adjusted automatically in order to ensure the coupling relationship among them.
fcenter =(fstart +fstop )/2
fspan= fstop- fstart
Where fspan is the SPAN.
Usage 1:
Set the center frequency point of the current screen through the STIMULUS→CENTER of the menu, and
display the values of the center frequency and sweep span, respectively, to the left and right of the bottom of
the grid.
In the lower-right corner of the pop-up Settings value screen, click to eject the soft keyboard and enter the
frequency value via the soft keyboard.
Please pay attention to the following points:
The start and stop frequencies will vary with changes to the center frequency when the span is constant.
In Zero Span, the start frequency, stop frequency and center frequency are always set to the same value.
Now, you can use PORT1 as a signal source for a fixed output amplitude, but it is important to note that this
machine uses the clock signal generator Si5351 as the signal source, the output signal is square wave, contains
a larger odd harmonic.
