Sample Rate Source
Selects whether the sample rate is estimated based on the digital input signal or is a
manually entered value (see also Chapter 3.3.4, "Important Signal Parameters and
Interface's Characteristics", on page 133).
"User Defined"
The sample rate is as defined the entry field value.
Note: An I/Q data clock is not necessary but the external signal
source (typically a second Rohde & Schwarz Instrument) and the
receiving Rohde & Schwarz Instrument have to be synchronized, i.e
they have to use common external reference signal.
"Digital I/Q In"
(for CODER connectors)
Estimates the sample rate based on the applied I/Q data clock and
displays the resulting value in the value field. The I/Q data clock sig-
nal is fed via the digital I/Q input.
Note: Estimation works best if the sample rate is close to the user
defined value.

Sample Rate Value
Sets the sample rate of the external digital baseband input signal. The max. sample
rate depends on the connected transmitting device.
