Using the Tracking Feature

Peaking

Peaking is the function that aligns the output filter (YTM) so that its passband is centered on the RF output, in CW or manual-sweep mode. Use peaking to obtain the maximum available power and spectral purity, and best pulse envelopes, at any given frequency above 2.35 GHz (or 2 GHz, when 2 GHz is the minimum frequency specified). The YTM is inactive for the low band frequencies

(10 MHz to 2.35 GHz).

To peak at the present CW frequency:

Press ( U S E R ) .

Select Tracking Menu Peak RF Once.

This causes an instantaneous execution of the peaking function. This is a one-time implementation of the peaking, where the function is turned on and then turned off.

To peak at the present CW frequency, and continue to peak at new frequencies as they are entered:

Press ( U S E R ) .

Select Tracking Menu Peak RF Always.

If “peak always” is on (denoted by an asterisk next to the key label) for an extended period of time, the peaking function will automatically repeak every seven minutes.

	Tracking
	Auto track is a more extensive version of peaking. It causes all of
	the YTM tracking calibration constants to be aligned and requires
	approximately 40 to 90 seconds to complete. Tracking is performed
	from 2.35 GHz (or 2.0 GHz) to the end of the specified frequency
	range.
Note
	If the synthesizer does not have a step attenuator, terminate the
	RF OUTPUT with a good 500 impedance match such as a 10 dB
	attenuator or a power sensor to prevent mistracking.
	To enhance the power output and spectral purity of swept
	modes, and to improve tracking performance (especially in harsh
	environments having wide temperature variations):
	Press (USERCAL).
	Select Tracking Menu Auto Track I
