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 connected probe for power calculations and measurements.
The value is used, for example, for scale calculation in the spectrum diagram.
