Atec Gigatronics-8650A Series - Manual (Page 4)

Or use our
exclusive fast
buffered
mode to
further
reduce processor overhead
and capture over 26,000
readings per second.
Incredible
speed for CW
and modulated
measurements
results from an
asynchronous
sampling rate of 2.5 to
5 MHz, that minimizes the
aliasing effects of signals to
produce faster average
power measurements.
And the 8650A features a
wide variety of statistical
power meas-
urement analy-
sis, to evaluate
communica-
tions system
efficiency.
BURST START AND
END EXCLUDE
The exclusive burst start and
end exclude capabilities of
the 8650A allow you to
exclude the beginning or end
of a burst when measuring
the average burst power.
Masking the beginning or
the end of a burst signal, in
order to exclude overshoot
or other distortions, can be
desirable or even required
for certain types of power
measurements.
CREST FACTOR
The crest factor capability of
the 8650A displays the ratio
of the maximum peak power
(peak hold) measurement to
the average power measure-
ment (in dB) from the time
the feature is enabled until it
is reset.
The crest factor capability
operates in the same manner
as the peak hold capability:
the display value holds at the
maximum until it is reset.
INCREDIBLE SPEED
AND STATISTICAL
ANALYSIS
No other meter delivers the
measurement speed available
from the 8650A.

ings per second over GPIB.
