Analog Measurements - Screens and Control Fields

Control Fields for Analog Measurements

	Input Port
	This field selects the RF IN/OUT or ANT IN port for making RF
	measurements. The RF IN/OUT port must be used for making TX
	power measurements.
	Operating Considerations
	If the RF power at the RF IN/OUT port exceeds allowable limits, a loud
	warning signal sounds and a message appears at the top of the screen.
	If this occurs, disconnect the RF power, reset using Meas Reset (press
	and release the Shift key, then the Hold key), and allow the Test Set to
	cool off for approximately two minutes before making any other
	measurements on this port.
	The ANT 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 on the RF ANALYZER screen using
	the ANT IN port.
	Connecting a signal of >60 mW to the ANT IN port can cause
CAUTION
	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.
	Maximum signal levels at the RF IN/OUT, DUPLEX OUT, and ANT IN
	ports are printed on the connector panel. Exceeding these levels can
	cause permanent instrument damage.

	Internal
	This field selects the trigger source.
	• Internal uses the signal being displayed for triggering.
	• Ext (TTL) uses the EXT SCOPE TRIGGER INPUT for triggering.
	This is a TTL level trigger (approximately 2.5 V).
