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

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.
