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
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
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.)
