Total List Length - Digital Modulation
Enters the length of the definition range of the control list in bits. The starting value is
always bit 0. The entire definition range is displayed, i.e. the bit scale is adapted to the
entry.
With very long control lists, the displayed area can be zoomed around the current cursor
position ("Zoom in" button).
The preset functions set the ramp in the center of the currently selected area.
If the definition range is decreased, the ramps outside the range are lost.
When used, the control list is always repeated over the length of the definition range if
the length of the data list exceeds the length of the control list.
SCPI command:
n.a.
Preset Type - Digital Modulation
Activates presetting for the ramp characteristic of the selected control signal. The pre-
setting is selected with "Preset Type" and activated by means of the "Preset" button.
You can select from:
"All Up "
The marker/control signal is continuously high.
"All Down"
The marker/control signal is continuously low.
"Ramp Up"
The marker/control signal contains a ramp from low to high. The ramp is
shifted to the center of the displayed signal area and can subsequently
be shifted as required.
"Ramp Down"
The marker/control signal contains a ramp from high to low. The ramp is
shifted to the center of the displayed signal area and can subsequently
be shifted as required.
"Ramp Up/
Down"
The marker/control signal contains a ramp from low to high and from high
to low. The ramps are symmetrically shifted around the center of the
displayed signal area and can subsequently be shifted as required.
"Ramp Down/
Up"
The marker/control signal contains a ramp from high to low and from low
to high. The ramps are symmetrically shifted around the center of the
displayed signal area and can subsequently be shifted as required.
SCPI command:
n.a.
Cursor Position - Digital Modulation
Enters the cursor position.
In the graphic display, the cursor is positioned according to the entry.
Vice versa, graphically shifting the cursor will change the displayed value.
If the entered value exceeds the selected length of the definition range, the length is
adjusted automatically.
SCPI command:
n.a.
