LTE cellular, etc.)? If yes, it is best to avoid these regions as the meter will either not see the signal of the CT-X, or sensitivity will be compromised. Generally, the further away from such signals the better. - Page 26 Chapter 2 Setting up Your CT-X All measurements taken will have an unknown amount of loss between the transmitters (plant and CT-X) and the instrument, so all adjustments will be made to balance the two signal sources relative to each other.

Page 27: Setting Up Your Ct-X
Chapter 2 Setting up Your CT-X Setting up your CT-X In this section, we’ll configure the CT-X to transmit the signals at their appropriate frequencies and at recommended levels. You can use a spectrum analyzer to iteratively set the levels of each signal at their appropriate levels. -

Chapter 2 Setting up Your CT-X 6 – Sets the spacing to 937.5 Hz 7 – Sets the spacing to 1093.75 Hz 8 – Sets the spacing to 1250 Hz 7. Navigate to the UNITS menu and select the units (dBmV or dBµV). -
Page 29: Example Tag Setup
Chapter 2 Setting up Your CT-X Example tag setup Choosing signal locations There is a large quantity of Seeker D units deployed already, so we will put a dual CW tag at 138 MHz to support that group. There is also an OFDM channel from 810 to 906 MHz and that’s the highest frequency the plant generates, so we will put 3 Chirp tags at... -

Page 31: Injecting Signals
Injecting signals Based off the cable length, tap, and rated combiner loss, we expect there to be around 16 dB of loss between the CT-X and where we are measuring. From this, the following parameters are calculated: Desired level measured at instrument for each signal... -
Page 32: Remeasuring Adjacent Channels
To make sure we did not impair any adjacent channels, we will re-measure the adjacent channels to make sure nothing was impaired. First however, we must disable Setup mode to put the CT-X in its final transmit mode. Ethernet setup The CT-X NETWORK menu is used to adjust the Ethernet settings of the CT-X and for configuration through the web interface. -
