Dependencies 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.
Couplings 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).
Initial S/W Revision A.07.00
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 A B C D CD E
Start Frequency
9 kHz 150 kHz 30 MHz 300 MHz 30 MHz 1 GHz
Stop Frequency
150 kHz 30 MHz 300 MHz 1 GHz 1 GHz Max freq of analyzer or 18
GHz, whichever is lower
RBW
200 Hz 9 kHz 120 kHz 120 kHz 120 kHz 1 MHz
Sweep Point
1411 6635 4501 11667 16167 Refer below.
Step Size
100 Hz 4.5 kHz 60 kHz 60 kHz 60 kHz 500 kHz
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
