  • GSP-830 User Manual 48 AMPLITUDE The Amplitude key sets the vertical attribute of the display, including the upper limit (reference level), vertical range (amplitude scale), vertical unit, and compensation for external gain or loss (external offset). Amplitude correction adjusts the frequency response distortion caused by external networks. The optional pre-amplifier GAP-801 and GAP-802 boosts the level of a weak input signal before it enters the GSP-830. The input impedance can also be adjusted according to the application needs.
