Hi

There's no comparison....

The 334A has an auto nulling feature on the distorton measurement that
can save ages of knob-twiddling manual nulling and it also measures
the distortion in an RF modulated audio signal.

The 334A is a nice, well built, piece of equipment. The only niggle I
have with it is why it reads +10dB for a 0dBu signal? I can live it it
though!

Yeah, auto-nulling is handy. The RF bit, i think, was an option (called
332), but i never had a need for one (yet). 331 is a pain to use, but,
considering how often i need to use it, it's not that big a deal... I also
noticed that i use the scope-out more than the meter - it's a hell of a lot
more useful to know what *kind8 of distortion you're getting... And I've
been using it less & less once i got a velleman scope (a 15Mhz digital scope
which uses your PC for display, storage, data manipulation & the front end -
has a nifty spectrum analyzer appy. Unlike the 'soundcard scopes, this
one's actually the real deal, check them out - they're annoyingly cheap &
can work with a laptop...) Still use the old tek as a 'workhorse" scope,
but a spectrum analyzer seems to be more informative than a dist. analyzer
when prototypin' stuff...


The 334A is a nice, well built, piece of equipment. The only niggle I
have with it is why it reads +10dB for a 0dBu signal? I can live it it
though!


It's still crippled with the min. .1% full-scale... And the fact that it's
neither tiny nor rackable 9without the 'unobtainable" kit) is another
weirdness... I had to build a little shelf for mine inside a rack...
