RF:MEASUre:ACPR:ADJACENTPAIRs
When the RF measurement type has been set to ACPR, the frequency domain
displays a Main channel in the center (Ch:Main), and a side channel group on
either side of the Main Channel. There can be either 1, 2 or 3 channels within
each side group; this command specifies that number. (Lower Area 1, 2 and 3
would be on the left side of the Main channel; Upper Area 1, 2 and 3 would be
on the right side).
To set the measurement type to ACPR, use the command
RFMEASUre:TYPe
ACPR
.
The Adjacent Channel Power Ratio (ACPR) is the ratio of channel power between
two user-selected channels (a side channel and a main channel).
NOTE. The oscilloscope will maintain the span to fit all the channels on-screen,
plus a margin of 10% (5% on either side.)
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.
