7.2.2.2 Select Band
Set up the analyzer for CISPR measurements quickly and easily. It contains controls to set the following
presets:
● CISPR Band A: 9kHz – 150kHz
● CISPR Band B: 150kHz – 30MHz
● CISPR Band C: 30MHz – 300MHz
● CISPR Band B&C: 150kHz – 300MHz
● CISPR Band D: 300MHz – 1GHz
This is same as the Meas -> Scan Config -> CISPR Band.
7.2.2.3 X-Scale
Set the scale type of X-axis to Linear (Lin) or Logarithmic (Log) scale.
In Log scale type, the frequency scale of X-axis is displayed in the logarithmic form.
7.2.3 Amplitude
Set the amplitude parameters of the analyzer. Through modifying these parameters, signals under
measurement can be displayed in a proper mode for easier observation and minimum error. Any change
of Ref Level, Attenuator Value, Preamp mode and Ref Offset will stop the running sequence.
7.2.3.1 Ref Level
Set the maximum power or voltage that can be currently displayed in the trace window. The value is
displayed at the upper left corner of the screen grid.
The maximum reference (Ref) level available is affected by the maximum mixing level; input attenuation
is adjusted under a constant maximum mixing level in order to fulfill the following condition:
Ref <= ATT - PA - 20dBm, where ATT = Attenuation value, PA = Preamplifier value
