Entry Scope that reads frequency good enough to do alignment on amateur radio
(1/3) > >>

So the hantek DSO2C10 is not reading close enough and in some cases not at all. My broken tektronix 2247a still reads frequency quite well but I thought the hantek would also. Also reads low res like 10.255mhz rather than 10.255xxx mhz.
Is there a cheaper scope like maybe a owon or something that will do this for me? I'm reading master oscillators and carrier osc and that type of thing.
tszaboo:
That's not the main function of an oscilloscope. What you need is a frequency counter. Some scopes have this built in, but you are probably better off with a cheap used unit from ebay.

I have some counters but they aren't accurate enough or sensitive enough.  Old heathkit and some mighty fine junk (mfj) my tektronix 2247a if it was fully functional is all I need.
I'm not sure what would be a good dedicated frequency counter these days.
RoGeorge:
The proper tool for radio alignment/repairs would be a spectrum analyzer.

There are plenty of frequency meters, some simpler designs for amateur radio (more or less just an Arduino with a display and some frequency dividers), others can be expensive standalone counters.  Some are ready made, others are as kits for hams to build.

Some signal generators also have counters, for example my DDS Rigol DG4102 has an input to measure frequencies with many digits, apart from the outputs that generates signals.

To answer the question, Rigol DS1054z is an entry level oscilloscope that has a hardware frequency counter with 6 digits.  Other models might have hardware counters, too, talking about DS1054z because this is the one I happen to have.
