Bit
Modulation
The Bit Modulation hotkey selects a bit sequence to be modulated onto the
generator signal.

Trans-
mission
The Transmission hotkey determines the shape of the generator signal (burst
signal or continuous wave with constant level). An 8PSK-modulated signal is
always bursted.

Marker
Display
The Marker/Display softkey positions up to 3 markers and a D-line in the test
diagram and displays their values.
If pressed once again, the selected Marker/Display softkey changes to the
Display/Marker softkey, see below.
Markers are graphical tools for marking points on the measurement curve and
for numerical output of measured values. The measurement menu
Power provides a reference marker and two further markers which
permit to measure differences (delta marker 1 and 2).
The coordinates of the three markers are indicated in the format
Ordinate value (level)/abscissa value (time) in a parameter line above
the test diagram. The position of the reference marker is expressed in
absolute units (level in dBm and time in symbol periods), the delta
marker by absolute or relative values (relative level in dB or time
differences from the reference marker).
D-line The D-line (display line) is a horizontal line that can be positioned on
the test diagram at will to mark and read out level values.
Ref
The hotkey Ref. R switches the reference marker on or off (use the ON/OFF key).
The reference marker is represented by the symbol in the test diagram. The
marker position (abscissa) is defined in the input field
Ref. Marker R . The marker
can be positioned to arbitrary time values. It is switched off in the default setting
(Off). The marker level is given by the measurement curve at the marker position.
The position of all markers can be varied using the rollkey.
Remote control
No command, screen configuration only.
Rel
The Rel. 1 hotkey switches the delta marker 1 on or off (use the ON/OFF key).
The delta marker 1 is represented by the symbol in the test diagram. The
marker position (abscissa) is defined in the input field
Rel. Marker 1 . The marker
can be positioned to arbitrary time values. If its position is outside the diagram area
it will be invisible and its coordinates will be “<abscissa_value> / - - -“. The marker
is switched off in the default setting
(Off). The marker level is given by the
measurement curve at the marker position.
The toggle switch Rel 1 Config pops up when the hotkey is pressed for the second
time. It defines whether the position of delta marker 1 is measured and indicated in
absolute units (dBm) or relative to the reference marker.
