deflnes the standard type as a short used for calibrating
reflection measurements Shorts are assigned a terminal
impedance of 0 ohms, but delay and loss offsets may still be
added.
is used to specify the in frequency steps instead
of number of points. Changing the start frequency, stop
frequency, span, or number of points may change the step size.
Changing the step size may change the number of points and
stop frequency in start/stop/step mode; or the frequency span
in center/span/step mode. In each case, the frequency span
becomes a multiple of the step size.
sets the starting stimulus value of a segment, using entry block
controls. The ending stimulus value of the segment is defmed
by the start of the next line segment. No more than one
segment can be over the same stimulus range.
adds or subtracts an offset in stimulus value. This allows limits
already
to be used for testing in a different stimulus
range. Use the entry block controls to specify the offset
required.
is used to the stop 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.
sets the stop frequency of a subsweep.
presents the store sequence to disk menu with a list of
sequences that can be stored.
is used to set the frequency of the source to sweep.
toggles between automatic and manual sweep time.
presents the sweep type menu, where one of the available
types of stimulus sweep can be selected.
reformats a reflection measurement into its equivalent SWR
(standing wave ratio) value. SWR is equivalent to (1
where is the reflection coefficient. Note that the results are
valid only for reflection measurements If the SWR format is
used for measurements of
