[Asterisk-Users] OT: Differences between test equipment

[tmassey at obscorp.com]

Hello!

Given the current discusison regarding ztmonitor, line testing, etc., I've 
been looking into purchasing a used transmission test set.  From my 
research, it seems that there are two items that might fit the bill:  the 
HP 3551A and the HP 4935A.

I know nothing about these specific devices.  I *do* have a good 
background in electronics, and I understand the concept what they're 
measuring and why., but I know nothing about the specifics of how this 
relates to transmission test sets!  :)  In fact, I'm not even sure that 
these are indeed the right devices for the job.

Could someone who is familiar with either of these devices tell me if they 
will fit the bill?  And if possible, which of these has more useful 
features as telephone line test equipment?  I'm handy with an 
oscilloscope, function generator, VOM, etc.  Will I be able to drive 
either of these?
