Fields
Input Port
This field selects the RF IN or ANTENNA IN port for making RF measurements.
Operating Considerations
Maximum power levels for each port are printed on the Test Set’s front panel. If
the RF power at the RF IN/OUT port exceeds allowable limits, a warning signal
sounds and a message appears at the top of the screen. If this occurs, disconnect
the RF power, press the Meas reset key, and allow the Test Set to cool off for
approximately two minutes before making any other measurements on this port.
The ANTENNA IN (antenna input) connector provides a highly-sensitive input
for very low level signals (such as “off the air” measurements). You cannot
measure TX (RF) Power, Average Power, Channel Power, or ACP Level on this
screen using the ANTENNA IN port.
CAUTION: Connecting a signal of >200 mW to the ANTENNA 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 ANTENNA IN port, and press the Meas reset key or turn the Test
Set off and on to reset it.
