Simple data patterns such as binary 0 strings or 1 strings can also be used as internal
modulation data. The "Data Source" selection from the menus is "ALL 0", "ALL1". A
variable bit string with a maximum length of 64 bits can be entered in an input field by
selecting "Pattern."
5.9.2.2
Internal Modulation Data from Lists
Internal modulation data can be generated and stored in the form of binary lists. A sep-
arate file is created for each list and held on the instrument's internal flash card.
The file name can be defined by the user.
The "Data Source" selection from the menus is "Data List". When this menu item is
chosen the "Select Data List" button appears; this opens the file-selection window for
data lists. A list can be created and edited in the "Data List Editor", which is accessed
from the menu via the "List Management" or "Data List Management" button.
The maximum length of a data list is determined by the size of the data list memory
(see data sheet). There is no restriction on the number of lists that can be stored.
5.9.2.3
Clock Signals
The clock reference used for generating the timing pulse can be either internal or
external ("Clock Source" selection from the menu: "Internal / External").
To enable a very precise simultaneous signal generation of two or more R&S SMBVs,
two additional clock signals, "Sync. Master" and "Sync. Slave", are available. These
both clock signals are enabled only in the special synchronistion mode. See
ter 5.9.2.4, "Synchronous Signal Generation"
on page 329 for information how to con-
figure two or more instruments to work in a synchronization mode.
Internal clock reference
The table below gives an overview of the generated clock signals and the connectors
they are output at for the case a internal clock reference is selected.
