Common Measurement Functions
FREQ Channel
FREQ Channel
Accesses a menu of keys that allow you to control the Frequency and Channel parameters of the
instrument.
Some features in the Frequency menu are the same for all measurements – they do not change as you
change measurements. Settings like these are called “Meas Global” and are unaffected by Meas Preset.
For example, the Center Freq setting is the same for all measurements - it does not change as you change
measurements.
Auto Tune/Zoom Center/Zone Center
The first key in the Frequency menu can be occupied by three different keys, depending on what View
you are in.

Auto Tune
Auto Tune appears as the top key in the Frequency menu in the Normal and Spectrogram views of the
Spectrum Analyzer Mode.
Auto Tune is an immediate action key. When it is pressed, it causes the analyzer to change Center
Frequency to the strongest signal in the tunable span of the analyzer, excluding the LO. It is designed to
quickly get you to the most likely signal(s) of interest, with no signal analysis knowledge required. As
such, there are no configurable parameters for this feature. There are only pre-selected values that work
in most real world situations.
Auto Tune performs a Preset as part of its function, so it always returns you to the Normal View and a
preset state, although it does leave the AC/DC coupling and Single/Cont state unaffected.
NOTE You may see a slight pause before the signal of interest is presented at midscreen.
