Figure 9.3.2.1: The spectrum with the receiving frequencies.

 A couple of steps later, there was a functionality problem with the exercise’s software

that worth mentioning.

The latest version of RFXpert was installed to the computer (version: 2.6.1). Although, at

the part of the exercise that we had to record a transport stream, it couldn’t. After some

searching on the internet with no results, I decided to contact the program’s company,

DekTec. After a lot of e-mails with the support service of the company, we found out

that there was a bug with the software and it was not able to record. The result was to

provide me with a beta version that was not released yet (version 2.6.2). Luckily the new

version was fully functioning and the rest of the exercise went smoothly.

9.3.3 DTA-115 exercise:

 In the beginning of this exercise the device connecting information before and after the

image were confusing and they were changed with a simpler explanation.

The original sentences were:

After that, insert the attenuator between the antenna and the TV EXPLORER.

Then connect the main output of the DTA to the TV EXPLORER.

They were replaced by:

Connect the attenuator to the TVexplorer and then connect the main output of the DTA-115 to

the attenuator.
