Calibration interface

The user need to calibrate before the measurement. This instrument use open short load (OSL) calibration. Users need to follow the instruction and connect open / short/50 Ohm load respectively to the RF port and do calibration.
Figure 21.: Calibration interface
The calibration interface is similar to measurement interface. On the left-top of screen including frequency information, On the left-bottom of screen including calibration information.
The user can save current calibration data to the local or external disk, or Import history calibration data to AC-726.
Before calibration, the user need to set the correct parameters, Mainly refer to the frequency and measurement points. The completion calibration, the corresponding curve will display on the screen. If calibration is valid, the status on the left-bottom will become “cal On”. If calibration is invalid or unfinished, the status will be “cal off”.
After the calibration, the user can return directly to the measurement interface for measurement.
System support different calibration kit only if user know the exact electrical length of open/short load. Users can input this parameters in the e parameter menu.

4 COMMON OPERATING INSTRUCTIONS

4.1

Set frequency parameter

The user needs to properly set the frequency parameter before testing. In the following ways users can enter the frequency setting interface.

In the "frequency return loss" or "frequency VSWR" or "cable loss
"measurement interface, click on the "parameter"
button
The user can also input frequency parameters in "DTF parameter setting"
interface
After entering frequency setting interface, the user can set start frequency and stop frequency through the following ways
Select pre-defined Signal standard
Manual input frequency parameter
Users can click on edit box to edit the parameter of frequency, system will pop up the soft keyboard. The user also can directly press the digital keys of hard keyboard.
The users need to select measurement points. System supports 4 options: 137, 275, 551, 1103.
If the measurement point is set to 1103, compared with the set to 551, it will take about 2 times longer measurement time. And so on.
NOTE: The minimum frequency interval is 1 MHz.
The start frequency range is 25~3999 MHz; The stop frequency range is 26~4000 MHz. The user can modify the pre-defined signal standard through PC software.
4.2

Set DTF parameter

The user needs to properly set the DTF parameter before DTF testing. In the following ways users can enter the DTF setting interface.
Enter the "DTF-return loss" or "DTF-VSWR" measurement interface, select "parameter
" menu.
April 2016 36
Page 37
Figure 39 DTF setting interface
The user can complete the following functions at the DTF parameter setting interface.
Enter frequency information and measure points.
Enter the distance information.
Enter the cable parameters.
Select the window function.
Set unit (support metric and Imperial).
NOTE: The user can modify the pre-defined cable parameters through PC software.
4.2.1
Distance parameters need to satisfy the testing needs, but also associated with the following parameters

Set Distance parameter

The operating frequency range (F1, F2).
The number of measured points (N).
Cable propagation velocity (Vp).
Once the user set the operating frequency, the number of measured points, cable propagation velocity, the maximum allowed cable length (D
) has be decided.

Page 38
For the convenience of users, the system will automatically display the relevant information (the maximum allowed cable length: Dmax; resolution Δ D) in the upper right corner.
For example: N = 551; Vp = 0.85; F1 = 25 MHz, F2 = 4000 MHz. The corresponding Dmax is 17.64 meters, Δ D is 0.03 meters;
Do not change the frequency, if users want to increase the allowed cable length, can increase the number of measuring points, the corresponding test time can also be longer.
NOTE: Due to the calculation of DTF, the minimum frequency interval is (N-1)
*100 kHz. If the measurement points is 551, corresponding minimum frequency interval is 55 MHz. The minimum distance interval is 1 meters (inch) or 1 feet (inch). Start distance range is: 0~Max-1; stop distance range is 1~Dmax.
4.2.2

Set Cable parameter

Users can manually input cable parameters (velocity; cable loss) or select the type of cable known.
The propagation velocity of electromagnetic wave in the cable is less than the vacuum speed (300M meters /second). Propagation constant is 0.85, meaning that the actual propagation velocity of the electromagnetic wave in the cable is the 0.85*300M meters / second.
When the user in the fault distance analysis, often want to know the return loss or VSWR of one exact connector. At that position, the cable loss and connector return loss will be mixed together, systems need to remove cable loss impact in the calculation connector return loss. The unit of cable loss is dB/ meter.
Users can select cable from pre-defined cable list. Usually the cable loss will vary with frequency .System will automatically calculate the cable parameters According to the cable parameters and working frequency.
If the user does not know any cable information and parameters, but have a cable at hand, users can use the system tools ("cable" cal) to get these parameters.
Click on the "cable cal" button in the DTF parameter interface, system will pop up one window. Users enter the measured actual length of cable (0.5~10 m); one end of the cable is connected to the RF port, the other end connected to open load or connected to nothing. Once the calibration is completed, the cable parameters will automatically refresh in DTF parameter interface.
April 2016 38
Page 39
Figure40.
4.2.3
In the distance to the fault analysis, if the location of the two connectors are close, because of the influence of spectral leakage, two connectors will be influenced each other. If return loss of one connector is much smaller than another one, most probably it will be lost and can’t be recognized. In this case users should choose to use the window function.

Set Window Function

System support four types window function: rectangle window, Hamming window, Keyser window, Blackman window.
4.3

OSL Calibratrion

The user needs to confirm the system is in "calibration valid" state before a test.
Before one test, system need to know beforehand the 3 known load (open /short/50Ohm) test results. The user can import the previous calibration data; or do OSL calibration before test.
The user can enter the calibration interface by the following ways.
In the main interface, click on "calibration" mode icon.
In the measurement of interface, click on the button "cal mode".
The OSL calibration procedure is as follows.
Set the frequency parameter.
Set up calibration parameters (optional).
Calibrate the first load.
Connect the load to the RF ports, click on the corresponding button.
The system will pop up a small window, click on the “OK”.
System start calibration.
Once calibration is completed the screen will display the curve.
Calibrate other loads.
If all calibration of three loads completed, the green "cal on" will shown at
the lower left corner of the screen.
39 April 2016
Page 40
Users can directly calibrate at the RF port, also can calibrate with a high performance cable connected to RF port. If the former, usually, the calibration curve of 50 ohm load will be significantly lower than the other two.
If calibration is completed, the user can start measurement.
The user can also select the file menu to save the calibration data in the local or external disk.
After the system boot, the default calibration data will be recent one.
The user clicks on the "file" menu, click "import", can recall previous calibration data. If the environment is similar, the previous calibration data can be used directly.
NOTE: Need to re calibration if frequency changed or measurement points increased
Need to re calibration if temperature changes a lot Do not need re calibration if measuring points reduced. Do not need re calibration if distance, cable parameters, window function changed.
4.4

Freq-Return Loss, Freq-VSWR, Cable-Loss measurement

The measurement can be used to verify the power matching of the port or the loss of the cable .X axis coordinate is frequency, Y axis coordinate are VSWR, or the return loss, or loss of cable separately.
In the following ways users can enter the measurement interface.
In the main interface, click on the "measurement
" icon, and then click the
corresponding icon.
In the measurement interface, the user can do a variety of measuring operation.
NOTE: Need to set proper frequency parameters before test
