The DLS 50 is a two wire cable simulator. The user can select the simulated cable
length using the keys on front panel, or via the IEEE 488 or the RS-232 interface. The
length can vary from 0 to the maximum installed length, in steps of 100 ft or 50 m.
Simulated Cable Type and Maximum Length:
The following table shows the various configuration available at this time:
Standard DLS 50 Extended DLS 50
24 AWG, 12 kft 24 AWG, 20 kft
26 AWG, 12 kft 26 AWG, 20 kft
0.4 mm PE, 3.6 km 0.4 mm PE, 6.0 km
0.6 mm German, 3.6 km 0.6 mm German, 6.0 km
The gauge and the length must be specified at the time of order.
Frequency:
The maximum frequency simulated is 500 kHz.
Accuracy:
The attenuation accuracy is within ±?5% ±0.2 dB of the response of an ideal cable in the
10 kHz to 50 kHz frequency range, ±4% ±0.2 dB from 50 kHz to 300 kHz and ±8% ±0.2
dB from 300 kHz to 500 kHz.
The phase, characteristic impedance and signal delay accuracy are all within 5%.
DC Characteristics
