"Multiple Sym-
bol"
A multiple of the symbol clock is supplied via the CLOCK connector, the
symbol clock is derived internally from this.
The "Multiplier" window provided allows the multiplication factor to be
entered.
Note: This setting is not possible if the serial or parallel external data
source is selected.
"Bit"
A bit clock is supplied via the CLOCK connector; the symbol clock is
derived internally from this.
Note: This setting is not possible if the serial or parallel external data
source is selected.
SCPI command:
[:SOURce<hw>]:BB:DM:CLOCk:MODE on page 625
Symbol Clock Multiplier - Digital Modulation
Enters the multiplication factor for clock type "Multiple".
SCPI command:
[:SOURce<hw>]:BB:DM:CLOCk:MULTiplier on page 625
Measured External Clock - Digital Modulation
Displays the measured frequency of the external clock signal. This enables the user to
permanently monitor the frequency of the externally introduced clock.
This information is displayed only if the external clock source has been selected.
SCPI command:
:CLOCk:INPut:FREQuency on page 526
Global Trigger/Clock/Input Settings - Digital Modulation
Calls the "Global Trigger/Clock/Input Settings" menu. This menu is used among other
things for setting the trigger threshold, the input impedance and the polarity of the clock
and trigger inputs.
In the case of two-path instruments, these settings are valid for both paths.
The parameters in this menu affect all digital modulations and standards, and are descri-
bed in the chapter 5.2.3.10, "Global Trigger/Clock/External Input Settings",
on page 137.

5.8.4 Arbitrary Waveform Generator ARB
The Arbitrary Waveform Generator (ARB) is an I/Q modulation source forming an integral
part of the R&S Signal Generator. It can be used to output any externally calculated
modulation signals or internally generated multi carrier signals or waveform files.
The Arbitrary Waveform Generator is incorporated in the Baseband Generator (R&S
SMU-B9/B10/B11) option. The Baseband Main Module (R&S SMU-B13) option is also
required.
