Using the
REF= FIXED MKR
1. To set the frequency value of a fixed marker that appears on the analyzer display, press:
∆
MODE MENU
Marker
FIXED MKR POSITION
enter a value from the front panel keypad.
The marker is shown on the display as a small delta (∆), smaller than∆ the inactive
marker triangles.
2. To set the response value (dB) of a fixed marker, press:
FIXED MKR VALUE
panel keypad.
In a Cartesian format, the setting is the y-axis value. In polar or Smith chart format,
with a magnitude/phase marker, a real/imaginary marker, an R+jX marker, or a G+jB
marker, the setting applies to the first part of the complex data pair. (Fixed marker
response values are always uncoupled in the two channels.)
3. To set the auxiliary response value of a fixed marker when you are viewing a polar or
Smith format, press:
FIXED MKR AUX VALUE
front panel keypad.
This value is the second part of complex data pair, and applies to a magnitude/phase
marker, a real/imaginary marker, an R+jX marker, or a G+jB marker. (Fixed marker
auxiliary response values are always uncoupled in the two channels.)
