The GOS-622G are general purpose analog oscilloscopes with 20MHz bandwidth, respectively. These products are designed for a wide range of applications ranging from product designs or assembly lines to EE laboratories or class experiments. Featuring a low vertical sensitivity at 1mV/div and versatile triggering, the GOS-622G can reliably capture small signals. The GOS-622G is the highest performance/price solution in the Test & Measurement market.

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.
