2. General Description and Features 
The GDS-806/810/820/840 is a useful, 2 channel digital storage oscilloscope with 
following features: 
z  Up to 250MHz (60MHz for GDS-806S/C, 100MHz for GDS-810S/C, 150MHz for 
GDS-820S/C and 250MHz for GDS-840S/C series) repetitive bandwidth and 
100MSa/s sample rate per channel (25GSa/s E.T. sample rate per channel). 
z  Up to 10ns peak detection for glitch capture. 
z  A large 5.7” mono or color LCD display (monochrome display for GDS-806S, 
GDS-810S, GDS-820S and GDS-840S, color display for GDS-806C, 
GDS-810C, GDS-820C and GDS-840C). 
z  Two input channels, each with a record length of 125k points and 8 bits vertical 
resolution. Both channels acquire waveforms simultaneously. 
z  Time base: 1ns/div~10s/div. 
z  6-digit trigger frequency counter. 
z  Auto-setting for quick setup and hands-free operation. 
z  Three Acquisition modes: Sample, peak detect, and average mode.
