ACPSP<br />

Channel Spacing<br />

Allows you to specify the frequency spacing between channels.<br />

Syntax<br />

- channel spacing 7 -<br />

HZ<br />

ACPSP Channel Spacing<br />

Item Description/Default Range<br />

Number Any real or integer number. Default unit is Hz. 1 kHz to 999.9 MHz.<br />

Equivalent Softkey: CHANNEL SPACING,<br />

Initial Value: 25 kHz.<br />

Preset Value: last value entered.<br />

Related Comm<strong>and</strong>s: ACP, ACPE.<br />

Example<br />

OUTPUT 718;"MOV ACPSP,lOOKHZ;" Spec@.es 100 kHz frequency spacing between channels.<br />

OUTPUT 718;"ACP;" Performs the adjacent channel power wxmsurenz-ent.<br />

Description<br />

The value of ACPSP is used when calculating the results of the adjacent channel (ACP) or<br />

adjacent channel extended (ACPE) measurement. The value of ACPSP is also used when<br />

ACPPAR is set for automatic coupling of the spectrum analyzer settings for the ACP, ACPE,<br />

C<strong>HP</strong>, or OBW measurement.<br />

Once you enter a value into ACPSP, that value is retained until you change it, or execute<br />

DISPOSE ALL. Pressing (JZF] or turning the spectrum analyzer off does not change the<br />

value of ACPSP<br />

You can execute the ACPSP comm<strong>and</strong> two different ways. You can either execute the ACPSP<br />

comm<strong>and</strong> directly (for example, "ACPSP 1OOKHZ ; I’) or use the MOV comm<strong>and</strong> to move the<br />

frequency value into the ACPSP comm<strong>and</strong> (for example, ~~MOVACPSP,lOOKHZ;"). If you use the<br />

MOV comm<strong>and</strong>, no text is displayed in the active function area during comm<strong>and</strong> execution.<br />
