4. Bond Wire Attachment
1. Devices labeled “For indoor use only” are not required to be equipped with bonding wire attachment points. Devices rated for exterior use must be equipped with bonding wire attachment points.
2. Integral bonding wire point must conform to the requirements of ANSI/SCTE 129 2007.
5. Labeling
1. Each port of the device must be labeled. Designations must be in accordance with the following:
• The forward input port label shall contain the word “IN” or “Input”.
• Output port label(s) shall contain the word “OUT” or “Output” and may include a port
number at the manufacturer’s option.
• Power port label(s) shall contain the word “Power” or “PWR.”
• The voltage and amperage requirements of the device shall be indicated on the label.
2. A label must he prominently displayed that will include information on the Return and Forward bandwidths.
A label must also display the nominal Forward gain from input to any output. Additionally, if Return amplification is incorporated, the nominal return gain shall also he included on the label.
3. Components which do not meet the environmental requirements of Section 9 shall be prominently and permanently labeled “For indoor use only.”
4. Labels shall include such other information as necessary to meet the requirements of other agencies. such as the FCC or recognized testing laboratories (UL, CSA etc.). Devices designed to be connected to commercial power shall include line voltage and power consumption information.
5. So long as the function of each port is clear and the gain from the input to each output port is clear, manufacturers may use any labeling layout they choose. See Figure 2 for an example of conforming labeling.
6.3. Gain
The forward and return gain of the device, measured from the input port to any output port for forward gain and from any output port to the input port for return gain, with all other ports terminated, shall match the labeled value with a tolerance of +2 dB/- I dB across the full specified forward and return bandwidths respectively. If the slope plus Ilatness of the device exceeds this tolerance, the slope shall be separately specified and shall be indicated on the label. All measurements shall be made using the methods specified in ANSI/SCTE 144 2012.
The return signal loss for devices without return amplification shall not exceed 2 dB for devices without internal signal splitting. For devices with internal splitting, additional loss is allowed in an amount not to exceed that specified in ANSI/SCTE 153 2008 for passive splitters with the same number of output ports.
6.4. Return Loss
The return loss, as measured at any RF port with all other ports terminated, shall he a minimum of 18 dB over the full specified forward and return bandwidths. All measurements shall he made in accordance with the procedures outlined in ANSI/SCTE 144 2012.
6.5. Port-to-Port Isolation
The port-to-port isolation as measured between any two output ports of a multiple output amplifier with all other ports terminated shall be a minimum of 20 dB for all devices over the full specified forward and return bandwidths. All measurements shall be made in accordance with the procedures outlined in ANS1JSCTE 144 2012.ANSI SCTE 161 pdf download.
