Hey guys what do you abot the LaCroy 9370L oscilloscope.
1GHz analog bandwidth, 500MSa/s in four channel mode and 1GSa/s in single channel mode. The 'L' variant (for Large memory) has 2M per channel which in single channel mode can be combined to 4M.
It is good?
Yes, the 9300 were very good scopes at their time. However, these scopes are now close to two decades old, and their processing is very slow (old Motorola 68k CPUs). In addition, while these scopes were generally very reliable, at this age the PSU might become a problem, as does the screen (most of the 93xx Series on the market have very bad burn-in marks, replacement CRTs are available but add to the overall costs). If it has the printer then it is prone to a capacitor failure which then prevents the scope from powering up. The encoders for the rotary dials often need replacing as well, spares are available from Mouser and are cheap but it's a lot of work to do. And if there's any problem with the ADC section then it's usually just 'game over'.
How is the maximum to spent for a working unit?
Depends on price, condition (most of these scopes seem to be beaten down), and what options it has (you want at least WP01, WP02 and WP03), and if it has the rare HDD option.
It also depends on what CPU board it has. There are two variants (actually three), two slower ones which can take less RAM (one if flash upgradeable, one isn't), and a faster one (CPU3 IIRC).
I guess the absolute limit for me would be somewhere around $500-$600 if it is in very good condition and has all the options.
For me it is a great machine.
It's still a great scope, albeit a bit slow, and with all the options still much more capable than most new entry level and even midrange scopes.
But it's still a almost 20 year old unit, and if your budget allows it I'd probably pay a bit more and get a LC 300/500 (CRT), LC 600 (LCD) or LT Series (LCD as well). Much faster processing, more/better options and the color screens make working with the advanced analysis capabilities much easier than the monochrome display of the 9300 Series. And especially in case of the LC 300/500 Series there are much more sellers than buyers at the moment.
