l) Typical Stabilization Time
The typical time interval needed to stabilize after changes in environmental conditions.
For a temperature change of 5°C then 30 minutes are required.
For a static pressure change of 5 kPa then 15 seconds are required.
For a humidity change of 30% (non-condensing) then 30 minutes are required.
m) Field Strength > 10 V/m
The Larson Davis model LxT2 was not measured for field strengths greater than 10 V/m.
n) Radio Frequency Emission
The mode of operation of the LxT2 that produced the greatest measurement radio frequency emission
levels was with the LxT2 set to run and with an LxT-EXC010 (10' microphone extension cable) used
to connect the PRMLxT2 to the LxT2. Adding the USB cable did not emit more radio frequencies
levels.
o) AC Power and Radio Frequency Susceptibility
The mode of operation of the LxT2 that produced the greatest measurement susceptibility to A.C.
power frequency and radio frequency fields was with the LxT2 set to run, USB cable attached and
with an LxT-EXC010 (10' microphone extension cable) between the PRMLxT2 and the LxT2.
