EQ Adjustment
The 5140 has two controls for cable equalization. The Coarse Eq control selects the
approximate length of the cable to be equalized, while the Fine Eq control is used to
precisely adjust the exact amount of equalization. The total equalization will be the sum
of the Coarse and Fine Eq settings.
The Coarse Eq setting is made through Avenue PC or the TouchScreen when the module
is in Remote. When the module is in Local, the Coarse setting is made with a rotary
switch located in the center of the module. It will most likely be necessary to remove the
module from the frame in order to adjust this switch. The Coarse ranges are:
0 - 200 feet 0 - 60 meters
200-400 feet 60 - 120 meters
400-600 feet 120 - 180 meters
600-800 feet 180 - 240 meters
800-1000 feet 240 - 300 meters
Once the Coarse Eq setting is made, the Fine Eq control is used to bring the total equal-
ization up to the proper amount. The Fine Eq control has an adjustment range of 0 to
250 feet (0 - 75 meters).
The final results should be verified by passing a known, reference signal through the
path. If using color bars, the Fine Eq would then be used to fine-tune the chroma
amplitude setting. A Sweep or Multiburst signal can also be used to verify (and adjust if
needed) for flat frequency response.
For setting the parameters remotely using the Avenue PC option, refer to the Avenue PC
Remote Configuration section of this document.
For setting the parameters remotely using the Avenue Touch Screen option, refer to the
Avenue Touch Screen Remote Configuration section of this data pack following
Avenue PC.
