Initial S/W Revision
Selecting a CISPR Preset will set the start/ stop frequencies, step size (according to sweep point), and
RBW of the selected range according to the table values shown below. Point/RBW will be set to 2 for
Discrete and Smooth scan type.
CISPR Band

9 kHz
Start Frequency
150 kHz
Stop Frequency
200 Hz
RBW

Sweep Point
100 Hz
Step Size
The sweep point is based on two points for each RBW width. It is the smallest odd number ≥ 2 × (Stop
Frequency—Start Frequency)/RBW. However, in this measurement, we are using step size instead of

This key is grayed out during multi range scanning. If the grayed out key is pressed, an advisory
message is generated. If the equivalent SCPI command is sent, this same message is generated as
part of a "–221, Settings conflict; Function not available while running multirange scan" warning.
This key is grayed out during final measurement. If the grayed out key is pressed, an advisory
message is generated. If the equivalent SCPI command is sent, this same message is generated as
part of a "–221, Settings conflict" warning.
Selecting CISPR Range Preset sets the EMI Standard in Mode Setup to CISPR. Selecting MIL
Standard Preset sets the EMI Standard to MIL. It will also set the Y Axis Unit to dBµV (unless dBµV is
grayed out, in which case it will leave the Y Axis Unit unaffected).
