SQ Cable Device

The SiN-1218A Smart iNode is designed to serve as an intelligent node within today’s HFC networks. It can be adjusted via Local Control Software (LCS) a computer or tablet. The device's USB port communicates directly to the Smart iNode controller. The no-touch Smart iNode delivers an innovative approach that enables significant operational savings for operators through automation. No manual configuration is necessary.

Features

l Supports 1.2 GHz downstream

Note:

1. Minimum receiver RF output level for the stated transmitter percent OMI per channel, with receiver optical input power of 0 dBm. To determine RF output levels at other optical input power levels, add (or subtract) 2 dB in RF level for each 1 dB increase (or decrease) in receiver optical input power.

2. Reference output tilt and internal tilt are both “Linear” tilt.

3. Forward internal tilt specified is primarily due to interstage equalizer and output equalizer on board.

4. The forward reference output tilt specified is the internal tilt of the launch amplifier and the tilt associated with the optical link.

5. The tilt is defined as the difference between the gain at the start frequency and the gain at the stop frequency 22dB tilt.

6. V_O=58dBmV at 1218MHz, 22dB tilt, 79 analog channels plus 111 digital channels.

7. 79 analog channels, NTSC frequency raster: 55.25MHz to 547.25MHZ, +36dBmV to 45.4dBmV tilted output level, plus 111digital channels, -6dB offset relative to the equivalent analog carrier.

8. Composite Second Order (CSO) – the CSO parameter (both sum and difference products) is defined by ANSI/SCTE6. Composite Triple Beat (selective voltmeter method), referenced to 100% modulation of the carrier being tested. Carrier to intermodulation Noise (CIN) – The CIN parameter is defined by ANSI/SCTE17.
