Adjacent Channel Power—Dynamic Range

 

Language Reference

 

SENSe Subsystem

Remarks:

With measurement type set at (TPR) total power

 

reference, 1.40 MHz is sometimes used. Using

 

1.23 MHz will give a power that is very nearly identical

 

to the 1.40 MHz value, and using 1.23 MHz will also

 

yield the correct power spectral density with

 

measurement type set at (PSD) reference. However, a

 

setting of 1.40 MHz will not give the correct results

 

with measurement type set at PSD reference.

 

You must be in Basic, cdmaOne, cdma2000, W-CDMA

 

(3GPP), W-CDMA (Trial & Arib), iDEN mode to use

 

this command. Use INSTrument:SELect to set the

 

mode.

[:SENSe]:ACP:DYNamic[n]:RANGe[m]?

Select a dynamic range optimization.

High - chooses settings that provide better dynamic range (better signal to noise ratio) at the expense of longer measurement times. This is a better choice for CDMA signals with multiple carriers turned on at the same time.

Normal - lets the measurement automatically choose settings that trade off dynamic range for faster measurement speed. This is a good choice for making CDMA measurements on a signal with only one carrier turned on at a time.

Modified- is not a customer settable option. This choice is automatically selected depending on your selection of other related settings in the advanced measurement setup, like the number of FFT segments.
