4. AMPLIFIER PATHWAYS :
The SAM-1C is equipped with very broadband amplifier trains that ensure an exceptional, very phase-clean
signal transmission. This is impressively proven by the following measurement reports. The balancing
amplifier module SSOM-04Mc, set to 0 dB gain (input signal level = output signal level), was driven by
square wave signals from a fast pulse generator.
Test signal Fig. 1: 1 kHz at a level of approx. 1.5V RMS (corresponds to +6 dBu line level) at a usual load
resistor of 10 kΩ. The wide frequency and phase response in the bass range and the clean processing of
even the deepest bass impulses can be seen from the barely visible slope of the roof.
Test signal Fig. 2: 10 kHz at a level of approx. 1.5V RMS. Load resistance of the oscilloscope during this
measurement: 300 Ohm. The very steep edges show the wide frequency response of the balancing amplifier
in the high frequency range. Even the fastest pulses are reproduced exactly!
