ANT IN
The antenna input is used for analyzing low-power RF signals (≤200 mWatts),
and is typically used for off-the-air measurements. This port can be selected in the
TX TEST, DUPLEX TEST, RF ANALYZER, or SPECTRUM ANALYZER
screens.
CAUTION: Connecting a signal of >200 mW to the ANT IN port can cause instrument damage
(although internal protection circuits can typically withstand a short-duration signal
of 1 or 2 Watts).
If the overpower circuit is triggered (signified by a warning message at the top of
the screen), remove the signal from the ANT IN port, and press [MEAS RESET]
or turn the Test Set off and on to reset it.
Operating Considerations
Input impedance = 50Ω
TX Power cannot be measured using this port; use the RF IN/OUT port. However,
low power levels can be measured using this port with the Spectrum Analyzer.
Additional sensitivity for this port is available using the
Sensitivity field in
the RF ANALYZER and SPECTRUM ANALYZER screens.
