Logic analyzers are really cheap compared to spectrum analyzers, though.
The 16500C is such a terrific deal on the used market because it has
Ethernet and no need to fuss with getting a PC with an HP-IB card or a
converter set up. (And you can put an okay if not great digital scope in
it
too.)
So point me at one for fifty bucks, and I'm in.... (seriously, I do
have a 16500B.......)
However, have you priced the blades?
They're not all that cheap unless you go for very early models, and
those have (to me) serious operability issues....
I'd start with the 166x series (myself), but I do like the 16500B (at
least) for the touchscreen interface..... The blades can kill you for
price, though.

The problem with a 16500B or 16500C for $50 if you find one at that
price you could easily pay that much for shipping if it's not local.
And if you don't pay that much for shipping it might be poorly packed
and get damaged during shipping. If you could also find a 16700A for
say $150 plus $50 in shipping in my opinion I would most often rather
have a bare 16700A for say $200 total than a bare 15600B or 16500C for
$100 total.
Which is a decent point. I'll put that on my list (but I think it's
going to be an eventual list).
"Blades" is not a term I have generally heard for the 16500/16700
series modules, but I'll go along with that.
I think I heard it here on this list, FWIW.
What do you think is a
reasonable price that won't break your bank for say a fully functional
16555A module with the POD1/POD2 and POD3/POD4 cable sets, but without
the breakout lead sets and grabbers? I ask because I have many more
16550A and 16555A modules than I have any need for that I should
unload.
I've gone one already, so that's working for me. hard to say, because
I'm inherently cheap. I can spring for things in the 50 dollar range,
but less is better, even better if it includes shipping. So you see,
my expectations are unreasonable.
I think I've seen them on Ebay for 75 to 100 dollars, and with the
cables (of course), finding the cables is difficult at best (from what
I've seen, then again, there's a lot of "not at that price" in my
world).
Also have excess 16700 mainframes. Located in WA, USA.
Hmmm..... Let me think about that. I've got LCD monitors, and I *do*
make use of the 16500B frequently. Something with a bit different
interface could be nice.
Also, regarding network control of 16500B / 16500C, you can only do
that on the 16500B if it has the optional 16500H or 16500L LAN
interface installed. Not all of them have that installed. If you do
have that one of the ways you can control the analyzer is to FTP a
plain text file containing a set of programming commands to the
\system\program file.
Haven't tried that, did try xwindows, had a fun time trying to make it
work on a PC... Kinda did....
I do have the LAN interface, though. Not sure which it is.
I've used that in the past to create new
configuration setups. I have found it much easier at times to keep
editing a text file and sending that to the analyzer to refine a
complicated configuration than to poke around at the touch screen
interface. For reference, see 16500H Interface Module LAN User's
Guide (May95), 16500-97013.
I generally do relatively simple things, like decode I2C and look at
it in the state machine view. That needed a custom pod, though.
The older use, debugging a microprocessor by looking at the address
and data lines, is a bit obsolete (although I do have some obsolete
equipment), but the newer microcontrollers can't be spayed upon that
way.
