TX Power Measurement

Transmitter power measures RF power at the RF IN/OUT port.

	Operating Considerations
	Only the RF IN/OUT port can be used for measuring TX power. When
	the Input Port is set to Ant, four dashes (- - - -) appear in place of digits
	for this measurement.
	Use the spectrum analyzer to measure low-level RF power (≤ 60 mW) at
	the ANT IN port.
	See “Input Port” on page 201 or “TX Pwr Zero” on page 221 for more
	information.
	Connecting a signal of >60 mW to the ANT IN port can cause
CAUTION	Connecting a signal of >60 mW to the ANT IN port can cause
	instrument damage (although internal protection circuits can typically
	withstand a short-duration signal of several 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 reset using Meas
	Reset (press and release the Shift key, then the Hold key) or turn the
	Test Set off and on to reset it.

	FM Deviation Measurement
	This is the default setting for this measurement field. The FM deviation
	measurement is the frequency deviation of the carrier. This
	measurement field is only displayed when the AF Anl Infield (on the
	AF ANALYZER screen) is set to FM Demod or FM Mod.
	See “Displaying AF Measurements” on page 57 for more information.
	See also “AF Anl In” on page 185.
