GBS-1204 - 4-channel Digital Storage Oscilloscope

This product is discontinued.

The GBS‐1000 series, an economical selection of the four‐channel DSO, offers three frequency ranges including 200,100, and 70MHz, real time sampling rate of 1 GSa/s, equivalent time sampling rate of 25GSa/s and 25k points memory depth.

The GBS‐1000 series has numerous features including 5.7” TFT color LCD display, 27 automatic measurements, FFT and FFTrms tests, 12‐graticule horizontal display, Go/NoGo for predefined conditions, and flexible interface selections such as USB and RS 232. By using the USB interface, users can save waveform images and waveform data as well as carry out waveform printout. The diversified features have made the
GBS‐1000 series the valuable choice of the economical four‐channel oscilloscope.

 

Signal Acquisition

The GBS‐1000 series features real time sampling rate of 1GSa/s and equivalent time sampling rate of 25GSa/s. The three built‐in signal acquisition methods are normal, peak detect and average. The flexible trigger type selections comprise edge, video (NTSC, PAL, SECAM) and pulse width. The trigger modes of edge and pulse include auto, normal and single.

25k Points Waveform Memory Depth

Oscilloscopes with long memory facilitate users to retrieve more waveform data in a certain period of time. The GBS‐1000 series, with 25k points memory depth, allows users to meticulously observe signals. Users, via the Acquire function of the GBS‐1000 series, can select 25k or 500 points memory depth to analyze complex waveforms or acquire fast updated waveforms.

Measurement Functions

The GBS‐1000 series provides 27 automatic measurement selections including voltage, period and time delay. Each channel can execute 5 measurement items simultaneously. 10 measurement results of two channels combined can be shown on the screen at the same time. All measurement results displaying on the screen allow users to efficiently observe all measurement parameters so as to better interpret
signals. Once the cursor function is on, the measurement target will be the signal within the cursor. After pressing Menu Off key, the measurement information will still be shown on the screen.

Complete vertical and horizontal expansion function

Users, via the GBS‐1000 series, can either select GND or the center of the signal to execute vertical expansion. Either the center of the signal or the vertical trigger point can be selected to carry out horizontal expansion. A sound signal expansion selection facilitates users to expand required signals for a detailed observation of signal trigger points.

Data Log

The data log function allows users to continuously record waveform data in a USB flash drive. After presetting time, interval and format for data recording the data log function will automatically record signals, which met trigger conditions. This function facilitates waveform recording for a long period of time that is beneficial to the observation and measurement result analysis afterwards.

Go/NoGo Test

The Go/NoGo function verifies whether or not the input signals are consistent with users’ preset conditions. Users have to preset waveform reference and signal conditions to activate Go/NoGo function and the Go or NoGo result will be shown on the screen instantly. Once the result is NoGo the GBS‐1000 will be sounding a buzz or sending out a control signal through the BNC output interface on the rear panel.
