which they occur. The carrier signal is generated at a frequency set
by the Base Frequency control (maximum 110 MHz for a ArbStudio
1102/1104 instrument), while samples of the modulating signal may
assume values between 0 and 360 degrees.
Modulating Table
Each row of the Modulating Table represents a time interval in which the
modulating signal may assume Constant values or Variable values

Constant Values - The modulating signal is kept at a constant value
for the entire interval duration. The corresponding row in the
Modulation Table is called an Entry.

Variable Values - The modulating signal varies within the time
interval, following a predefined behavior. The corresponding row in
the Modulation Table is called a Segment.
The first column contains the modulation coefficients or the Segment
names, while the second column contains the corresponding duration. The
time sequence of each table item can be modified by dragging an entry in
the desired position.
PLEASE NOTE THE FOLLOWING:

The Duration and Amplitude values inserted in the table are
automatically rounded depending on the sampling rate and on the
instrument resolution.

The Memory Usage indicator visualizes in real time the occupation
of the hardware resources.
Command Bar
The Command contains the following 6 buttons for editing the Modulation
Table.

Clear the Modulation Law

Delete the selected Entry or Segment on the Modulation Table
