Instek GOS-630FC - 30MHz 2-Channel Analog Oscilloscope
LCD Readout Display, Frequency Counter, and Auto Time-Base setting
GW Instek is announcing a brand new 30MHz Analog Oscilloscope, GOS-630FC, to the global
market. Besides the functions of a basic oscilloscope, GOS-630FC is equipped with more useful features to create a
new benchmark for the oscilloscopes within the same category. The new innovative functions, including LCD Readout
Display, Frequency Counter, and Auto Time-Base setting, are provided as
standard features of the product. GOS-630FC, with a bandwidth elevated to
30MHz and additional valuable features, is priced at the level of a fundamental
oscilloscope. The add-on value without additional cost make GOS-630FC a
most beneficial choice among the entry-level analog oscilloscopes available in
the market today.
1mV/div High Vertical Sensitivity GOS-630FC, with high vertical sensitivity up to 1mV/div, is able to capture the small signals of the input source. Wide
ranges of vertical, horizontal, and trigger settings make GOS-630FC a full-fledged oscilloscope. Additional functions
such as XY mode display, MAG function (Time based Magnified), and Z-axis Input extend the application range of
GOS-630FC to both the education and industry fields.
LCD Readout Display & Real-Time Frequency Counter Vertical/Horizontal settings and input signal Frequency of GOS-630FC are shown on a bright and clear LCD display
simultaneously. Users could easily know the current setting status from the
small LCD screen instead of checking the knob positions. GOS-630FC
automatically counts the frequency of the input signal and shows this reading
on the display. This is a good feature rarely seen on a basic`oscilloscope
.
Auto Time-Base Intelligent Operations
GOS-630FC provides “Auto Time-Base” function, which is seen only in digital or high-end analog
oscilloscopes, to automatically select the appropriate horizontal time base for waveform display.
Buzzer alarm reminds users when the Vertical/Horizontal setting reaches the maximum or minimum
boundary.
High Product Quality with Economic Price
GOS-630FC is a highly reliable product guaranteed by an ISO certified manufacturing system. Hundreds of quality
tests have to be passed upon completion of the manufacturing of each unit. Economic price and remarkable functions
like LCD readout display, 5 digits real-time counter, and Auto Time-base make GOS-630FC a product with the best
price vs. performance ratio in the oscilloscope market.
