For example, frequency converter com- ponents with an embedded local oscillator (LO), such as a CATV tuner, low noise block (LNB, down converter of satellite TV parabola antenna) of satellite communications, or similar components. Embed- ded LO signals of these devices are sometimes not accessible from outside and are difficult to lock the phase between RF and IF signals when measuring. Note: The USB power sensor control for power calibration of the ENA is not yet supported with Firmware version 9.1 or earlier firmware versions Note: Vector network analysis is not available using power sensors. Operation of Frequency Offset Mode and Its Limitation Keysight network analyzers (PNA series and ENA) have a frequency offset mode (FOM) option1 that allows users to set source or receiver port frequency independently. When using FOM, frequency converter devices can be measured precisely and accurately2. The operation requ
