Transmission Measurements
The S820E can measure insertion loss of cables (or other 2-port devices) using
three different methods. If you have access to connect only one end of the
cable to the instrument, then you must perform either One Port Testing using
Cable Loss - One Port mode, or two port Transmission measurements using
an external USB sensor.
For One Port Testing, the other end of the cable must be terminated in a
short or open to provide a full reflection of the signal. This method provides
accurate results when the cable loss is less than 10 dB.
When the cable loss values are higher than 10 dB, then the two-port method
must be used to obtain accurate results. If you are able to connect both ends
of the cable to Port 1 and Port 2 of the Site Master (either directly or through
a port extension cable), then you can use the 2-port Transmission method. If
you are able to connect only one end of the cable to the Site Master, then you
can use the Transmission measurement with External Sensor.
