The 50MHz GOS-653G Series is an example of classic analog oscilloscope design. The GOS-653G cover a broad range of industry applications, such as product design, assembly lines, repair & servicing, and educational purposes for EE laboratories and class experiments. Coupled with various trigger functions (Auto, Norm, TV), complex waveforms can be easily triggered for use in diverse applications. The ALT Trigger function enables users to observe signals from dual channels simultaneously. The Hold Off function helps stabilize sophisticated signals within repetitive frequencies or periods. Delayed sweep magnification (GOS-653G) can display and zoom in waveforms at the same time. For classic design and operation applicable to a wide range of applications, the GOS-653G Series offers extra value.

In a workshop environment with mostly artificial lighting, the cursor display text is reasonably legible. However ... in a room with more ambient light, the cursor readout can be too faint to read (and please note that there is no direct sunlight on the unit shown below, and the text display brightness is at maximum) The questions... 1) Is there any way to boost the brightness of the cursor information display? 2) If not, does the 6051 (or any other) model have a brighter text readout?
Most of analog (CRT) oscilloscope under the strong light environment usually its result of shown not very good, certainly this includes our GOS-6031 too.
In order to solve the issue, we offer the following solution as below;
1.Adjust the trace intensity in the front panel 2. Adjust the readout intensity in the front panel
The pushbutton is for selecting the text readout intensity function or scale illumination function, and indicates the letter “TEXT” or “ILLUM” in the readout. Press the pushbutton for the following sequences:
“TEXT” --> “ILLUM” --> “TEXT” (Step 1)
The TEXT/ILLUM function are associated the VARIABLE(Step 2) control knob. Turning the knob clockwise to increase the text intensity or scale illumination, while turning the knob counterclockwise to decrease it.
If the methods of the above are all unable to reach the anticipated, we think perhaps 50MHz model will be a good choice too, because the luminance of CRT is sure to batter than 30MHz
For analog oscilloscope, some got CH1 signal output, and some have Trigger signal output, are both same meaning?
From following picture you can find there are totally different signal. CH1 signal output will be same with CH input signal, and Trigger signal output will be like pulse signal.
Why is the low frequency of the oscilloscope CRT brightness so dark? it can not be the appropriate observed signal.
Because CRT of 30MHz does not have Third Accelerating Anode (P3) to accelerate the high voltage, so the luminance of trace should not be too bright.
The scope display changes with instrument attitude. With inputs grounded the trace positions change in X and Y axis and in rotation by approx. 2mm as the instrument is moved from face vertical to face horizontal position.
Because of CRT relation of physical characteristics so the trace of the oscilloscope is very easy to be influenced, so when you change the direction of the oscilloscope, usually the trace will be influenced by magnetic field of the earth, which is the reason why the oscilloscope usually all have a Trace Rotation function.
