Using cable folder
In DTF measurement, you are required to input the
velocity factor and the average cable loss (dB/m). In
case that you do not remember the velocity factor and
the average cable loss of the cable-under-test, use the
cable folder to find the cable type.
When you are making a DTF measurement, pressing
{Cable}
brings up a dialog box for frequency band
selection first. You should select any of the following
categories:
• Standard (measure in 1000 MHz)
• Standard (measure in 2000 MHz)
• Standard (measure in 2500 MHz)
• Customized cables
Press [ENTER] to confirm the selection. Then the tester
displays a cable list in the frequency band. Each
category of cables is listed with cable type velocity
factor and average cable loss.
If you wish to create customized cable library, you need
to use N9330B Post Analysis Tool to send the
customized cable list to the tester.
