				Function Keys
12. INCR SET	This key is used to display or set the increment value.
	1	Press		.
	1	Press	INCR SET	.
	2	Enter an increment value using the DATA keys.
13. LO LIMIT	This key is used if you want to be alerted when a measurement is less than a
	speciﬁed value.

To Set a Low Limit

•Position the cursor at the measurement field of your choice.

•Press SHIFT

•Press ⇓ (LO LIMIT).

•Enter the value you want the lower limit to be.

• Press ENTER or a units key. A LO (or L) annunciator will appear.

If a limit is exceeded during a measurement, a beep will sound (the beeper ON/OFF control can be found in the Conﬁgure screen) and “Measurement low limit exceeded” will be displayed. The LO annunciator will also ﬂash as long as the measurement is displayed.

To Turn Off (or On) a Low limit:

When a limit is turned off, its value is retained but is not used.

•Press SHIFT

•Press ⇓ (LO LIMIT).

•Press ON/OFF

14.MEAS ARM This key is used to arm a one-time-only (Meas Trig, Single) measurement. After MEAS ARM is pressed, the instrument will wait for a valid trigger event, then make the measurement currently selected. Meas Arm only applies to Phase/Freq, Pwr Ramp, BER, Output RF Spectrum, and Pulse On/Off measurements. It can be particularly useful for measuring RACH bursts.
