My First Scope was a DS2072A
i haven't used the DS1074Z
but i do know this,...
- Rigol is a Cheaper Scope, than, let's say Tektronix
- My Scope is a 2 Ch, Yours is a 4 Ch (This is a question of personal preference and needs)
- My scope is a 70MHz upgraded to 300MHz
- I have 2GSa/s you have 1
- I have 56Mpts Memory depth, You have 24Mpts i think
all these things come down to personal choice and needs
as far as the scope itself is concerned
Regardless of Model, All the Rigol's are a good first scope
even the OLD DS1052E
i don't recommend the old Technology, but.. Hey, if that's your budget and you want a decent first scope, Rigol is a Good Little Scope to work with,
i don't think you'll regret the decision
I'm comparing my scope with a freind who bought a Tek about 7 Years ago it had 200MHz, 4 CH anaolgue Input, i think 24Mpts memory depth
he still swears by his scope as being reliable, but thinks that mine is better than his
but , in all fairness, I"m comparing a new Rigol with an Old Tek (it's not a fair comparison)
Tektronix is better than Rigol any day of the Week, if you can stomach the Budget to get one, if you can't .. Get a Rigol
i think, you've done well in your choice
enjoy Your Scope
