Jupiter - DOCSIS Design Verification System

Test Coverage

Jupiter provides the most comprehensive PHY testing for the DOCSIS 1.1., 2.0 and 3.0 protocols. It tests thousands of parameters and performs tens of thousands of single and bonded-channel measurements.

It incorporates the latest RF measurement technology and test equipment available, forming a complete platform for all of your DOCSIS testing needs in a single, mobile rack.

Jupiter Triggering

  • USB-2101
    • TDMA/SCDMA upstream trigger card
    • Works for all DOCSIS 1.x,2.0, 3.0 single-channel bursts, & 3.0 PHY 18
    • RF detector with microprocessor design
    • Can specify level (threshold), duration and RF present/absent
    • Built-in filters to smooth symbol noise
    • Detected RF and trigger test ports
  • Software “triggering”
    • Used to detect when all four channels are bursting at the same point in time
    • Used in multiple-channel (N > 1) test situations
    • Probability game
    • Default retries set to 10
    • Temporary solution until CableLabs Test MIB #123 works
Test Test Description DOCSIS 3.0 Additions to DOCSIS 2.0
PHY-01.3 CM Input Power and Frequency Range Differences in frequency range but otherwise identical to PHY-01.2
PHY-05.3 J.83 Annex B Interleaving Adds procedures for 4 bonded downstream channels and three different interleaver settings
PHY-07.3 Bit Error Rate and Codeword Error Rates One test case for total input power increased from 30 dBmV to 33 dBmV and changes for extended frequency range
PHY-10.3 Upstream Frequency Accuracy Additional test procedures for 5-85 MHz frequency range
PHY-12.3 Upstream Channel Transmit Power Adds procedures for dynamic range window challenge, no global reconfiguration time power tests, and incorporates MIB power functions of MP-01.2
PHY-15.3 Carrier Power Flatness Similar, but multiple burst structure added
PHY-16.3 CM Randomizer and Preamble Adds procedure for SCDMA Mode 2
PHY-17.3 Upstream Spectrum and Out-of-Band Noise and Spurs Adds procedures for multiple cases of bonded channels with varying power within bonded channels and added frequency ranges
PHY-18.3 Upstream Spectrum and Out-of-Band Noise and Spurs (Off Burst) Adds procedures for multiple cases of bonded channels (between bursts) and added frequency ranges
PHY-20.3 Pre-equalizer Test Adds procedures for 2, 3, and 4 channel bursting
PHY-21.3 CM Receive Power Test Differences in frequency range but otherwise identical to PHY-21.2
PHY-23.3 Symbol Rate Change Similar, but with multiple active upstream channels
PHY-24.3 Modulation Error Ratio (MER) Similar, but with multiple active upstream channel cases and extended frequency ranges
PHY-25.3 Clock Synchronization Identical to PHY-25.2
PHY-27.3 Code Hopping Similar, but with multiple active upstream channels
PHY-29.3 CM Return Loss - Manual Test Using Network Analyzer New for DOCSIS 3.0, no 2.0 equivalent. Tests CM return loss across frequency range using a network analyzer
