Figure 4 – 4: VSA Analysis of PUCCH Data
Controlling PXT in Record Mode
In this mode the PXT is able to capture between 12 ms and 200 ms of IQ data. It then writes this data to a
file which enables the VSA to replay the recording and make post-processing measurements.
On the PXT/VSA Communicator user interface, perform the same steps: 1-7, as stated above in live mode.
Then on the PXT perform the following steps:
8. Start recording on the PXT by selecting: Mode > SA > Agilent VSA > Record VSA > Start.
9. After the PXT has finished recording, you can save it to a file by selecting: Mode > SA > Agilent
VSA > Record VSA > Save.
The data is saved in a file on the PXT at this location:
D:\Program Files\Agilent\E6621A\CaptureData.
10. You can now use the PXT/VSA Communicator software to transfer the file from the PXT to the PC
hosting the VSA software using the following steps:
a.
Verify that the IP address of the PXT is correct.
b.
Open the connection.
c.
Retrieve the list of file names by selecting Get File List or Get File
d. Select the file you wish to copy.
e. Copy the desired file to the hard drive of the VSA host PC.
