Table 5: Sample
clock generator
Characteristics Description
Sample rate The sample clock frequency is a global parameter that applies to all channels. DDR can be
enabled on a per channel basis allowing the sample rate to be doubled on selected channels.
The sample cl
ock frequency is always between 2.5 GHz and 5 GHz. To achieve sample rates
lower than 2.5 GS/s, the system replicates points. The number of replicated points increases
by powers of 2, therefore the clock frequency is SR×2
n
,. where n is an integer that results in
a frequency
between 2.5 GHz and 5 GHz.
When using complex waveforms digital up conversion, the sample rate is limited to 2.5 GS/s to
5 GS/s. To achieve lower sample rates, use w aveform interpolation.
DDR enabled:
Real waveforms: 596 S/s to 10 GS/s
Complex (I
Q)waveforms:5GS/sto10GS/s
DDR disabled
Real wave
forms: 298 S/s to 5 GS/s
Complex (IQ) waveforms: 2.5 GS/s to 5 GS/s
Sample rate resolution
Jitter Reduction Mode (PLL
integer mode)
3 digits with jitter reduction (50 M Hz sample clock frequency s teps from 2.5 GHz to 5 GHz).
With DDR enabled, the resolution is 100 MHz Sample rates below the clock range are a power
of 2 div
ision of the clock frequency so Low Jitter s ample rates are a power of 2 divisions of
the 50 MHz stepped frequencies.
Without Jitter Reduction (PLL
FracN mode)
8digit

Table 6: Analog output skew
Characteristics Description
Skew between (+) and (–) outputs
±15 ps
Skew between channels
±25 ps
Skew is calibrated using the (+) outputs of the DC High BW output path for each channel.
Channel delay will change when a different path is selected or when various DAC features are
enabled.
Delay change from DC High BW
output path to other output paths
DC High Volt
(Option HV)
1.2 ns
AC Direct
340 ps
AC Amplified
(Option AC)
740 ps
Skew adjustment range
±2 ns
Used to adjust skew between channels in a single instrument.
