ACP Measurement Results<br />

Description units<br />

1CPERR A variable that indicates if setup errors occurred for the ACP measurement. None<br />

If ACPERR is 0, no errors occurred. If ACPERR is greater than 0, an error<br />

occurred. An ACPERR value of 1 to 7 indicates that the frequency span,<br />

channel spacing, or the channel b<strong>and</strong>width are not set correctly. An<br />

ACPERR value of 1 to 7 indicates the following:<br />

KPPWRTX<br />

KPMAX<br />

KPLOWER<br />

LCPUPPER<br />

‘RA<br />

1 Frequency span < (2 x channel spacing + channel b<strong>and</strong>width).<br />

2 Channel b<strong>and</strong>width > 2 x channel spacing.<br />

3 Frequency span < (2 x channel spacing + channel b<strong>and</strong>width) <strong>and</strong><br />

channel b<strong>and</strong>width > 2 x channel spacing.<br />

4 Channel b<strong>and</strong>width < frequency span/loo.<br />

5 Frequency span < (2 x channel spacing + channel b<strong>and</strong>width) <strong>and</strong><br />

channel b<strong>and</strong>width < frequency span/loo.<br />

6 Channel b<strong>and</strong>width > 2 x channel spacing <strong>and</strong> channel b<strong>and</strong>width<br />

< frequency span/loo.<br />

7 Frequency span < (2 x channel spacing + channel b<strong>and</strong>width), channel<br />

b<strong>and</strong>width > 2 x channel spacing, <strong>and</strong> channel b<strong>and</strong>width < frequency<br />

span/loo.<br />

A variable that contains the total transmit b<strong>and</strong> carrier power. ACPPWRTX Determined by<br />

is calculated by the following: AUNITS comm<strong>and</strong><br />

Default unit is dBm.<br />

10 x b(Powe~carTier)<br />

A variable that contains the relative power level of the adjacent channel<br />

with the highest measured power level.<br />

A variable that contains the relative power level found in the lower<br />

adjacent channel. ACPLOWER is calculated by the following:<br />

P’-‘~e%wer channel<br />

10 x log( 1<br />

PoweTcarrier<br />

A variable that contains the relative power level found in the upper<br />

adjacent channel. ACPUPPER is calculated by the following:<br />

Restrictions<br />

Executing ACP exits the following functions: windows display mode (WINON), N dB point<br />

measurement (NDBPNT), the FFT menu measurements (FFTAUTO, FFTCONTS, FFTSNGLS),<br />

gate utility functions (GDRVUTIL), TO1 measurement (TOI), marker table (MKTBL), peak table<br />

(PKTBL), percent AM (PCTAM), or peak zoom (PKZOOM).<br />

AUNITS of W or V, will give incorrect results for ACPMAX, ACPLOWER, <strong>and</strong> ACPUPPER.<br />
