Select number of averages, n, for <strong>Peak</strong> power measurements. Higher numbers will<br />
reduce noise effects and provide more stability at low power levels.<br />
(n = number from 1 to 999 - higher than 4 is recommended).<br />

☛ NOTE: It is important to remember that no data can be taken in the <strong>Peak</strong> Mode unless a<br />
trigger is occurring. This is indicated by the flashing of the New Data light on the front<br />
panel. See External Triggering in Section 3.2.5.<br />

Sample Program:<br />
Set channel A reference delay. (Arbitrary timing point to which other timing<br />
measurements are related.) (n = microseconds)<br />
Set channel B reference delay. (Arbitrary timing point to which other timing<br />
measurements are related.) (n = microseconds)<br />
Min Value: 0 µs<br />
Max Value: 213999.97 µs<br />
Set channel A cursor delay. Sets timing position of the Cursor on the graphic<br />
display. The Cursor is the vertical line located where the power reading (CSR PWR)<br />
is being taken. [Timing is related to the Reference Delay (REF DLY)].<br />
(n = microseconds; s = polarity)<br />
Set cursor delay for channel B. Sets timing position of the Cursor on the graphic<br />
display. The Cursor is the vertical line located where the power reading (CSR PWR)<br />
is being taken. [Timing is relative to the Reference Delay (REF DLY)].<br />
(n = microseconds; s = polarity)<br />
