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 −10 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" field on page 178 for more information.
