DSP-100/2000

Users Manual

DC Loop Resistance

Range: 0 to 400Ω

DSP-100 accuracy: ±(500 mΩ +1% of reading)

DSP-2000 accuracy: ±(2Ω +2% of reading)

Resolution: 0.1Ω

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.
