Installation Procedure

PLM860SAW

Installation

It is recommended that assistance be available to safely install equipment in equipment racks.

1. Install chassis in equipment rack (equipment rack sold separately) by supporting the bottom and rear of PLM860SAW at the desired eleva- tion in rack.

2.Line up the side holes of chassis with the tapped equipment rack holes.

3Insert the provided screws through the side holes in chassis and thread into the tapped equipment rack holes.

4.Fasten the bottom screws first, then fasten top screws (tighten securely).

5.Connect a cable from the output of the video source to the video input connector of the PLM860SAW.

6.Connect a cable from the output of the audio source to the audio input connector of the PLM860SAW.

7.Connect a cable from the output RF connector of the PLM860SAW and the input connector of combining system.

8.Connect power cord to receptacle supplying uninterrupted line power (LED on front panel will illuminate).

9.Connect a cable between the front panel output test point and a spectrum analyzer or signal level meter. Measure the video and aural carrier level.

10.Adjust the aural carrier level to 15dB below the level of the video car- rier by slowly rotating the AURAL LEVEL adjustment on the front panel of the PLM860SAW.

11.Connect a cable between the combining system test point and a spectrum analyzer or signal level meter. Measure the video and aural carrier level of the PLM860SAW and adjacent channels.

12.Adjust the Output level of the PLM860SAW to match the video and audio carrier levels of adjacent channels by adjusting the OUTPUT LEVEL adjustment on the front panel of the PLM860SAW.

Signal Combining Methods

PICO MACOM recommends connecting the headend components in the following manner: Each of the modulators, signal processors or strip ampli- fiers output are connected to a combining network. Either a PHC-12Gor a PHC-24Gheadend combiner may be used to accomplish this purpose.

The PHC-12Gor PHC-24Gpassive headend combiner consists of two rows of directional couplers combined by a hybrid splitter. Normally, the odd channels are combined on one row while even channels are combined on the other row of directional couplers for maximum isolation. The output of the combiners may be connected to the input of a launch amplifier such as a CA-30RK550or CA-30RK1000. The output of the amplifier is con- nected to the main distribution line.

The CHC16U/550 and CHC16U/860 sixteen channel active combiners provides both signal combining and post amplification of the headend signals. Up to 16 channels may be combined using the CHC16U. The combiner gain is 15 dB per channel.

A 24 channel system hook-up is shown. (The same combining result may be accomplished by using a single PHC-24G).

The two PHC-12Goutputs are combined via a two-way splitter, which is connected to a CA-30RK1000launch amplifier. The input levels to the combiner, whether from a modulator, signal processor or a strip amplifier, must be at the same amplitude.
