I have been using the oscilloscope a lot and I have some comments. Although most are already handled in various tests. The performance of the oscilloscope is excellent one must say, but it may be overly sensitive to high frequencies. However, if one activates the 20 MHz limit on the channels and sets "Auto Bandwidth Limit" to "3", and then saves the whole configuration by clicking "Save Current Configuration", the instrument becomes less sensitive to high frequencies – and also starts up in that mode after turned off. You can always change the bandwidth back to the required level as needed. High bandwidth (higher than needed) and amplification often lead to unwanted interference.
One of the most frustrating aspects of using the oscilloscope was plugging in the connectors to the input and the generator output. Although the modified variant is better, it's not perfect either. Therefore, I created a simple extension that works well, which you can see in the pictures. Two cheap BNC extenders and some scrap stuff plus a little work made the trick.
Regarding the question of whether type 1 or type 2 is better, I think Type 2, that version has larger keys and is easier to insert the BNC connectors in. Bigger keys are better to operate. It may also lock better. However, I chose Type 1 because of its lower price. The performance of both types is identical - they only differ in their wrapping as far as I can see.
An updated manual is also attached 😊
