What is the power level of different measurement channels of the PNA network analyzers at preset?
Each channel is initiated with the nominal power level, even if a User Preset is saved with a different power level for the starting channel. Therefore, if you save channel 1 with a nominal power level of 60 dBm as a User Preset, then start channel 2, channel 2 will start with the nominal power level (17 dBm for an option loaded E8364B). Be careful if you set up a new channel. You could damage the components, if you did not anticipate the high power levels. If you had RF power Off at the User Preset level for channel 1 and then you started a channel 2, then RF power would be off on channel 2 also. RF Power is a global parameter, versus the power level setting, which is a channel parameter.
