Planar IT-100 Operating Manual page 39

To set up the page, specify the following parameters:
1) Page name. Can be edited with pressing «F2 / Rename» key;
2) Channel plan. Channel plan with channels set for measurement. Can be selected
one of the channel plans of internal disk or external USB flash drive. Selected
channel plan data is copied to CDL page, so, editing or deleting selected channel
plan will not affect the page;
3) Limit plan. Limit plan with measurement results checking limits defined. Can be
selected one of the limit plans of internal disk or external USB flash drive.
Selected limit plan data is copied to CDL page, so, editing or deleting selected
limit plan will not affect the page;
4) AMP powering. Switching off/on supplying external devices via RF input (for
example antenna amplifier);
5) AMP voltage. External devices supplying voltage: 5, 12, 24 V;
6) Test point compensation. Turning off/on compensation of signal attenuation at
test point;
7) Test point attenuation. Test point attenuation value in dB: 0...40 dB;
8) Measure. Selecting parameters for measuring (affects measurement duration):
All parameters – measure all the parameters, Level only – measure only
channels level, Level + CN/MER – measure Level and channel C/N or MER;
9) Precision/Speed. Select the balance between measurement results precision
and measurement duration: Fast – fast measurement without averaging
– acceptable measurement duration with some averaging, Precise – high
measurement duration with strong averaging.
All the parameters except for Channel plan and Limit plan can be modified before
measurement.
