• Structured test signals (for SDH as described in ITU-T Recommendation O.172)
• Sine wave modulation
• Standard filters: Highband
Measurement error
The stated measurement error applies without restriction to standard range, for values
>25 UIp in extended range.
• Maximum measurement error: ± R % of reading ± W
The value for W (fixed error) is taken from
can be taken from ITU-T Recommendations O.172 (04/2005) and O.173 (03/2003) as
applicable.
