ANTENNA IN
The antenna input is used to analyze low-power RF signals (≤ 200 mW), and is
typically used for off-the-air measurements. This port can be selected in the
CONFIGURE, CDMA REVERSE CHANNEL SPECTRUM, analog TX TEST,
DUPLEX TEST, RF ANALYZER, or SPECTRUM ANALYZER screens.
Operating Considerations
•BNC
• Input impedance = 50
Ω
• 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
analog RF ANALYZER and 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 over-power circuit is triggered (signified by a warning message at the top of the screen),
remove the signal from the ANT IN port, and press the
Meas reset key, or turn the Test Set off and on to reset it.
