10 MHz offset (baseband gain: 6 dB) 73 dB (typ.)
Digital I/Q inputs
standard in line with Rohde & Schwarz TVR290,
I/Q data and control signals, data and
interface clock

Interface
data rate 66 MHz to 100 MHz
source user-defined, digital I/Q in
sample rate 400 Hz to 100 MHz
resolution (user-defined) 0.001 Hz
I/Q sample rate
(max. sample rate depends on interface
data rate)
With source ‘user-defined’, the sample
rate must be entered via the parameter
‘sample rate’, no I/Q data clock being
necessary. With source ‘digital I/Q in’, the
sample rate will be estimated on the basis
of the applied I/Q data clock.
frequency uncertainty (user-defined) < 5 × 10
− 14
resolution 18 bit
logic format two’s complement
bandwidth
sample rate = 100 MHz
(no interpolation, user-defined) 40 MHz
I/Q data
sample rate < 100 MHz (interpolation) 0.31 × sample rate
markers 4 Control signals
data valid valid samples marked in data stream
