IF test using RP-050 |
The IF TEST function allows to check buildings cabling system before the antennas and head-end systems are operative. For this application PROMAX has specially designed RP-050, RP-080 and also RP-250 signal generators.
The main difference is the RP-050 covers satellite IF while the RP-080 covers also the terrestrial band. The RP-250 is an agile signal generator with selectable frequency and level across the 5-2500 MHz band.
The procedure allows to evaluate the frequency response across the whole TV signals distribution network by means of two steps. |
 Step 1: Calibrating with TV Explorer |
|
Connect the generator directly to the TV EXPLORER and calibrate. The instrument compensates all the cable and connector drops and sets signals at the detected frequencies as the reference. |
| Step 2: Measure pilots throughout the network |
|
Once calibrated, start to make level measurements in each outlet. On the screen will appear the attenuation values for the pilot frequencies measured in the different testing points.
