Internationalstandards (MKK method)
are written around this so the fastest
mode has minimal errors due to
acceleration.

MEAS/USER
ACCELRAT FASTER Speeds up the ACP measurement with a minimal
affect on the accuracy or repeatability. Sweep speeds or
measurement techniques are changed to allow faster
measurements than those described by the standards.
The techniques used to speed up the measurement
depend on the method being used. These techniques
may allow a small difference in the measured ACP ratio
(1 dB error in amplitude).
Front-panel key access:
MEAS/USER
ACCELRAT FASTEST Speeds up the ACP measurement significantly at
the expense of up to 2 dB of difference from using the
normal speed. The techniques used to speed up the
measurement depend on the measurement method
selected.
Front-panel key access:
MEAS/USER
ACCELRAT NORMAL Selects the normal measurement speed. The
measurement speed is limited by the requirements of
the standard. The technique for making the
measurement is in accordance with the applicable
standards committee documents for the chosen method.
No speed-up techniques are used, therefore, there is no
additional measurement error due to the use of
speed-up techniques.

MEAS/USER
ACP AUTOMEASURE Measures the power that "leaks" from the
transmitter output into the channels that are adjacent
to the carrier. ACP AUTO MEASURE performs an
automatic measurement which calculates the ratio of
the "leakage" power in the adjacent channel to the total
power transmitted by a transmitter. ACP AUTO
MEASURE uses the measurement method that you
have selected and changes the instrument state to
ensure that a valid measurement is made. The
instrument state parameters that can be affected are
frequency span, resolution bandwidth, video
bandwidth, and detection mode. Center frequency and
reference level, are not affected.
