External attenuation: Scale, Attenuation
Consider a voltage divider that is part of the DUT before the measuring point. The
external attenuation is included in the measurement, and the instrument shows the
results that would be measured before the divider. External attenuation can be used
with all probes.
"Scale"
Select linear or logarithmic attenuation scale.
"Attenuation"
Enter the attenuation of the voltage divider according to the selected
scale. The conversion from linear to logarithmic values depends on
the "Vertical unit" of the probe:
For voltage-based unit (V and A):
attenuation (dB) = 20 * log
10
(attenuation factor)
For power-based unit (W):
attenuation (dB) = 10 * log
10
(attenuation factor)

Impedance
Sets the impedance of the channel for power calculations and measurements.

Coupled to C1 / C2 / C3 / C4
Channel coupling sets the vertical settings of the coupled channels to the values of the
active channel. If you want to have the same vertical settings for two or more channels,
you can set them at once by coupling these channels.
Channel coupling affects all vertical settings that are adjusted in the "Settings" tab: ver-
tical scale, position, offset, coupling, and ground.

5.5.5 Digital filter setup
Access: "Vertical" menu > "Digital Filter"
After processing by the A/D converter, the channel and trigger signals are digitized sig-
nals. These digitized signals can be filtered to reject high frequency - also known as
Digital Signal Processing (DSP). You can filter the acquisition channels.
One filter is applied to a channel.
If High Definition mode (option R&S RTP-K17) is installed, digital filter settings are
enabled automatically. You can change the high definition bandwidth in the "Digital Fil-
ter Setup", which is applied to the channels.
