Re marks: Sets the low level av er ag ing win dow for the sen sor. At reso lu tion set -
tings of 0.01 and 0.001dB, digi tal read outs may flicker due to the high
read ing rate of the ML2400A Se ries. Low level av er ag ing ap plies a low
pass fil ter to post- average data read ings to achieve a more sta ble front
panel dis play with out slow ing down the re sponse of the me ter to larger
changes in level. The three win dows for LOW, ME DIUM and HIGH low
level av er ag ing are
± 0.01, 0.02, and 0.05 dB.
For ex am ple: When a LOW set ting of low level av er ag ing is ap plied while
step ping from 0 dBm to –1 dBm, the me ter dis plays the fi nal read ing
within 0.01dB with no de lay. The fi nal set tling of 0.01dB will set tle over
a short sub se quent pe riod of time, lead ing to a sta ble high reso lu tion
read out.
With a HIGH set ting of low level av er ag ing, the set tling win dow is in -
creased (up to ap proxi mately 0.05 dB) and the set tling time is longer.
With low level av er ag ing OFF, the me ter dis plays the fi nal read ing in -
stantly with no fur ther set tling ob served. Any jit ter due to noise is re -
flected in the dis played read ing, which may be in con ven ient for high
reso lu tion read ings.
