Network Analyzer
? ??????????????????????????
A UTO SCALE Brings the trace data (dened by the
? ???????????????????????
SCALE FOR key) in view on the display with
one keystroke . Sweep values are not aected, only scale and reference values . The
analyzer determines the smallest possible scale factor that will put all displayed data
onto the vertical graticule .
?????????????????????
SCALE/DIV Changes the response value scale per division of the displayed trace . In Smith, polar ,
and admittance chart formats , this refers to the full scale value at the outer
circumference and is identical to the reference value .
????????????????????????????????????????????
REFERENCE POSITION Sets the position of the reference line on the graticule of a Cartesian display (with 0 at
the bottom line of the graticule and 10 at the top line). It has no eect on a Smith,
polar or admittancechart format. The reference position is indicated with a small
triangle just outside the graticule , on the left.
???????????????????????????????????????
REFERENCE V ALUE Changes the value of the reference line , moving the measurement trace
correspondingly . In Smith, polar and admittance chart formats , the reference value is
the same as the scale and is the value of the outer circle .
????????????????????????????????????
MKR!REFERENCE Makes the reference value equal to the marker's absolute value(regardless of the delta
marker value). The marker is eectively moved to the reference line position. In
Smith, polar and admittance chart formats this function makes the full scale value at
the outer circle equal to the marker response value .
???????????????????????????????????????
SCALE FOR [D A T A] Selects one of the \D A T A" and \MEMORY" traces to be scaled by prior functions in this
menu.
? ?????????????????????????????????????????????
D&M SCALE [COUPLE] Couples or uncouples the \D A T A" and \MEMORY" traces to be scaled by prior functions
in this menu. This is valid only for those traces obtained by the display menu accessed
from the 4
Display
5 key .
????????????????????????????????????????
A TTENU A TOR MENU Displays the menu to control the attenuation at the following ports .
? ??????????????????
A TTEN R Controls the attenuation at port R.
????????????????????
A TTEN A Controls the attenuation at port A.
? ??????????????????
A TTEN B Controls the attenuation at port B .
??????????????????????????????????????????????
TEST SET A TTEN PT1 Controls the attenuation at port 1 of an S-parameter test set that is connected to the
analyzer .
?
?????????????????????????????????????????????
TEST SET A TTEN PT1 Controls the attenuation at port 2 of an S-parameter test set that is connected to the
analyzer .
