Power
Transmitter (TX)Power
TX Power is only measured and displayed here when the Input Port
on the RF ANALYZER screen is set to RF In. If Ant (antenna) is
selected, the measurement is replaced by four dashes (- - - -).
You can measure low power levels on the ANT IN port using the
spectrum analyzer.
Refer to “TX Power Measurement” on page 183 and “TX Pwr Zero” on
page 221 for more information on measuring transmitter power.
CAUTION
Connecting a signal of >60 mW to the ANT IN (antenna) 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, remove power from the ANT IN port and turn the
Test Set off and on to reset it.
