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

the start frequency of a frequency range.
When the

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).
After each standard is deflned, including offsets, press

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

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.

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.
