About 4 year ago I blew up a Panasonic scope I was using for many years. I collect and repair antique radios and I found using a scope makes life easier. Did not have much money at the time so I purchase an Owon D6062V for about $300, similar Tek at that time was double the price. From that time I have found several old Tek scopes, on ebay or Craiglist, which I have repair or waiting to be repaired. One of my finds was Tek 2465 not working, I repaired it and now sits on my bench besides the Owon, I use both of them constantly.
I was tinkering with a circuit that put a sine wave at about 22MHz, the Owon has measurements right on the screen and I saw the circuit putting several volts more than the power supply. That was odd and after making sure that the setup and probes where in the right position I decided to connect the Tek. It showed the amplitud of the wave at the value anticipated. So I decided to test the two scopes with my function generator a Rigol DG1022U which goes up yo 25MHz.
The amplitud shown on the Tek is steady up to very near the 25MHz when it drops a little. On the Owon once you get past around 10MHz the amplitud starts to increase, gets to a maximum around 20MHz (around 30% more amplitud) then it goes down when approaching 25MHz by 40% with respect to the Tek.
On the Owon i'm using a T5060 a 60MHz probe and on the Tek a TP6100 a 100Mhz probe.
The Owon supposed to be a 60MHz scope, is this normal?
