Change

This field defines the type of power control bits that will be sent to the mobile station when Execute is selected. The range over which the mobile station will be commanded to change its power level is determined in the Steps field.

•n Up sends a series of “0” power-control bits, causing the MSUT to increase its power, then returns to the "normal" sequence.

•sends a series of “1" power-control bits, causing the MSUT to decrease its power, then returns to the "normal" sequence.

•Ramp sends a series of "n up" followed by a series of "n down" bits.

GPIB Example

“DISP CTXR;CDMA:PCONtrol:CHANge ‘n up’”

selects “n up” power control steps.
