turns the adjacent channel power graph ON or OFF. With ACPGRAPH ON, the ACP ratio graph is calculated and displayed and the numeric results are not displayed.
The value of the ACP ratio is displayed at the selected marker frequency offset from the center frequency. This graph function is used after doing an adjacent channel power measurement with the ADJ CHAN POWER or
AD3 CHAN PWR extd softkeys.
measures the power leakage into the adjacent channels and calculates the adjacent channel power ratio of both the upper and lower channels, with respect to the total power. The total power of the carrier is displayed. The adjacent channel power ratios of both channels are also displayed and the larger number is marked with a A. (Vertical lines on the display indicate the bandwidth edges of the three different channels being measured.)
The measurement can be made on a single sweep or continuously updated at the end of each sweep. (See
SINGLE MEAS and CONT MEAS .) The measurement stops and the analyzer is returned to its prior state when other measurement functions are activated.
