Frequency Error, Frequency

RF Frequency Error and RF Frequency are displayed on the RF

ANALYZER, RF GENERATOR, and AF ANALYZER screens.

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.
	Connecting a signal of >60 mW to the ANT IN (antenna) port can cause
CAUTION
	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.
