selects whether spur avoidance is ON or OFF. Selecting spur avoidance OFF, along with selecting raw offsets OFF, saves substantial time at recalls and during frequency changes Spur avoidance is always coupled between channels.

is used to deiine the start frequency of a frequency range. When the Istart_) key is pressed it becomes the active function. The value is displayed in the active entry area, and can be changed with the knob, step keys, or numeric keypad.

calculates and displays the mean, standard deviation, and peak-to-peak values of the section of the displayed trace between the active marker and the delta reference marker. If there is no delta reference, the statistics are calculated for the entire trace. A convenient use of this feature is to find the peak-to-peak value of passband ripple without searching separately for the maximum and minimum values.

The statistics are absolute values: the delta marker here serves to detlne the span. For polar and Smith chart formats the statistics are calculated using the first value of the complex pair (magnitude, real part, resistance, or conductance).

defines the standard type to be a load, but with an arbitrary impedance (different from system ZO).

deties the standard type as a transmission line of specified length, for calibrating transmission measurements.

defines the standard type as a load (termination). Loads are assigned a terminal impedance equal to the system characteristic impedance ZO, but delay and loss offsets may still be added. If the load impedance is not ZO, use the arbitrary impedance standard definition.

dehnes the standard type as an open used for calibrating reflection measurements Opens are assigned a terminal impedance of infinite ohms, but delay and loss offsets may still be added. Pressing this key also brings up a menu for defining the open, including its capacitance.
