Agilent Technologies 8935 series e6380a manual RF In/Out, RF Level Offset

Configuration - Screens and Control Fields

Control Fields on the Configuration Screens

RF In/Out

This field is used to indicate losses or gains between the RF IN/OUT port and the device-under-test.

•Enter a positive value to indicate a gain (such as an amplifier gain). When the RF IN/OUT port is used as an output, the RF generator’s (or tracking generator’s) level is automatically set the specified amount below what is indicated in the RF generator’s Amplitude

field. Example; if this value is 10 dB, and the Amplitude field shows 0 dBm, the actual level out of this port is −1 0 dBm.

When this port is used as an input, the TX Power measurement and spectrum analyzer’s marker level (Lvl) are automatically reduced by that amount.

•Enter a negative value to indicate a loss (such as cable loss). The RF generator’s (or tracking generator’s) level out this port is automatically set that amount above what is indicated in the RF generator’s Amplitude field.

When used as an input, the TX Power and the spectrum analyzer’s marker level (Lvl) measurements are increased by that amount.

This field is only used when the RF Level Offset field is set to On.

See the “RF Level Offset” on page 246 for more information.

RF Level Offset

This field enables/disables the RF level offsets entered in the RF In/Out, Duplex Out, and Antenna In fields below it.

•When set to On, the RF generator’s amplitude and RF analyzer’s power measurement are offset by the values entered in these fields.

•When set to Off, the values in these fields are ignored.
