Accuracy

Attenuation:

100 kHz to 200 kHz

± (1 dB +6% of attenuation in dB) for attenuation up to 60 dB.

200 kHz to 15 MHz:

± (1 dB +4% of attenuation in dB) for attenuation up to 60 dB.

15 MHz to 20 MHz:

± (1 dB + 6% of dB attenuation) for attenuation up to 60 dB.

20 MHz to 30 MHz

± 3 dB for attenuation up to 60 dB.

DC – 4 kHz:

Max attenuation: 30 dB @ 4 kHz.

Delay/Characteristic

Impedance:

± 10%.

Mechanical

Connectors:

Front (simulated line):

CF Connectors (Banana Plug).

Back (noise):

BNC Connectors (2 differential mode, 2 common mode).

Dimensions:

20.2" x 17.8" x 8.2"

(L x W x H).

Net Weight:

60 lbs.

Environmental

Operating Temperature:

10°C to 40°C.

(50°F to 96°F).

Relative Humidity:

10 to 95% RH non-condensing.

Electrical

Power:

90 to 260 V AC, 50 or 60 Hz.

Fuses:

Type “T” 2 A/250 V SLOW BLOW (2 required, 5mm x 20mm).

Noise Injection

Externally generated noise can be injected onto the simulated line at both the ONU side and the NT side independently.

Differential Mode:

Max input level: 0 dBm.

50 Ohm BNC input.

20 dB fixed attenuation.

Common Mode:

Max input level: +10 dBm.

50 Ohm BNC input.

0 dB fixed attenuation.

NB:

Differential mode and common mode are not mutually exclusive.

Simulated line impedance over the whole frequency range is unaffected by either differential or common mode noise injection.

Standards

The DLS 8100 simulates the Bypass, VDSL1, and VDSL 1 with Bridged Tap loops in accordance with ANSI Draft Technical Report on

System Requirements for VDSL (VDSL SR:98-043R6).
