Related Peak Power Commands
AVPK Select number of averages, n, for Peak power measurements. Higher numbers will
reduce noise effects and provide more stability at low power levels.
(n = number from 1 to 999 - higher than 4 is recommended).
TRGAsnn.nn Internal trigger level, channel A
TRGBsnn.nn Internal trigger level, channel B
(s = polarity; n = dBm)
Min Value: -10.00 dBm
Max Value: +16.00 dBm
TRGE External triggering
☛ NOTE:
It is important to remember that no data can be taken in the Peak Mode unless a
trigger is occurring. This is indicated by the flashing of the New Data light on the front
panel. See External Triggering in Section 3.2.5.
RDLAnnnnnn.nn Set channel A reference delay. (Arbitrary timing point to which other timing
measurements are related.) (n = microseconds)
RDLBnnnnnn.nn Set channel B reference delay. (Arbitrary timing point to which other timing
measurements are related.) (n = microseconds)
Min Value: 0 µs
Max Value: 213999.97 µs
CDLAsnnnnnn.nn Set channel A cursor delay. Sets timing position of the Cursor on the graphic
display. The Cursor is the vertical line located where the power reading (CSR PWR)
is being taken. [Timing is related to the Reference Delay (REF DLY)].
(n = microseconds; s = polarity)
CDLBsnnnnnn.nn Set cursor delay for channel B. Sets timing position of the Cursor on the graphic
display. The Cursor is the vertical line located where the power reading (CSR PWR)
is being taken. [Timing is relative to the Reference Delay (REF DLY)].
(n = microseconds; s = polarity)
Min Value: 0 - Reference Delay
Max Value: 213999.97 µs - Reference Delay
