New Bench-Mark of Mainstream DSO
GDS-820/GDS-840 series DSO, at 150MHz/ 250MHz bandwidth with color or Mono LCD display, are designed and built to meet the demands of a modern DSO in the main stream market today. The unmatched performance, user-friendly design and versatile interface make GDS-820/840 a very useful equipment for most of the applications in various fields.

Superior DSO Performance
With Equivalent Time Sampling Technique, GDS-820/840 series perform up to 25G S/s sampling capability and provide high resolution of 40ps for repetitive waveforms. Comparing with 1GS/s and 2GS/s sampling DSOs, GDS-820/840 gives higher or equal sampling rate and longer record length of a transient signal at the same time-base because of its 125K long memory. Furthermore, this series offer an alternative to view the signal with 12 horizontal divisions, which matches long memory applications! GDS-820/840 advanced trigger functions, such as Pulse Width, TV Line, Event-Delay, and Time-Delay, offer a very strong trigger capability that could only be found in a high-end DSO!

Valued Plus Features The FFT function converts a captured waveform from time domain into frequency domain. The Go-No Go function gives an instant view of the performance of a DUT or provides an easy way to baby-sit the abnormal event of a signal. The Learn Mode and Auto Setup Sequence function let the user complete his ATE test procedures without software programming. With almost everything you could expect from a DSO, GDS-820/840 provides you with the best solution for waveform measurements at a surprisingly affordable price.

User-friendly Design
The straightforward operation of GDS-820/840 lets the user get started with DSO measurements right after the power-on! The Auto-Set function enables the DSO to automatically adjust the set-up and display the waveform in a proper way! The on-screen Help Manu tells you the operation information you need. Besides, 15 auto measurement functions of GDS-820/840 give you direct readouts of most of the frequently measured parameters!

Versatile Interface GDS-820/840 series (except GDS-820) provide various kinds of interface including USB, RS-232 and Printer Port as standard, and GPIB as optional. With USB and software, you can quickly send the signal from DSO to PC within a very short time. This enables the nearly synchronous waveform displays on both the DSO and the PC screen.
