SpectraDynamics DS-100 Operating Instructions

PECTRA

Description

The DS-100 is a 4 channel distribution and isolation amplifier. Typical cross channel isolation is 70 dB and reverse

isolation is typically greater than 70 dB. The phase noise of the modules is exceptionally low, typically –150 dBc/Hz

@ Fourier frequency of 10 Hz and –170 dBc/Hz @ Fourier frequency greater than 10 kHz. Both the input and output

are matched to 50 ohms to obtain better than 15 dB return loss.

The DS-100 operates on a dual DC power supply. The dual DC power supply should be able to provide 250 mA on

both the positive and negative supply. The DC voltage should be ± 12 VDC. For optimum performance the

following specifications should be used for the power supply.

Positive Supply

Negative Supply

Output ripple

The power supply should have current limiting features as well as over-voltage protection.

WARNING! DO NOT APPLY AC VOLTAGE TO THIS UNIT! Applying AC power to this unit will cause injury or

death to personnel, cause irreparable damage to the instrument and void all warranties.
