Overload recovery time: Less than 10 minutes to rated accuracy following an
overvoltage. Self-calibration is required after repeated or prolonged overvoltage.
Attenuation
The following attenuation specifications are defined per TIA TSB-67.
Frequency Range: 100 kHz to 105 MHz in 100 kHz steps. Range is determined by
the selected test standard.
Amplitude Range: 0 to >30 dB (random noise floor for NEXT: 30 dB)
Resolution: 0.1 dB
Return Loss: Better than 15 dB from 1 MHz to 100 MHz. Typically better than
20 dB.
Dynamic Accuracy: Better than
±
0.75 dB from 1 MHz to 100 MHz. Typically
better than
±
0.25 dB at 30 dB of attenuation from 1 MHz to 100 MHz.
Measurement Accuracy (calculated from above parameters): Better than
±
1.0 dB
from 1 MHz to 100 MHz. Typically better than
±
0.3 dB at 30 dB of attenuation
from 1 MHz to 100 MHz.
NEXT
The following NEXT specifications are defined per TIA TSB-67.
Frequency Range: 100 kHz to 105 MHz in 100 kHz steps. Range is determined by
the selected test standard.
Amplitude Range: 85 dB at 1 MHz to 65 dB at 100 MHz (residual NEXT: 10 dB)
Resolution: 0.1 dB
Return Loss: Better than 15 dB from 1 MHz to 100 MHz. Typically better than
20 dB.
Dynamic Accuracy: Better than
±
0.75 dB from 1 MHz to 100 MHz. Typically
better than
±
0.6 dB.
Residual NEXT Loss (after connector compensation): Better than 55 dB at
100 MHz.
