The manuals (service and user) for the HP1745 are on line at:
http://www.home.agilent.com/agilent/techSupport.jspx?pid=1745A%3Aepsg%3Apro&pageMode=MN&cc=US&lc=eng&pselect=SR.PM-Find%20by%20Product%20Model%20Number%20-%20Manuals.Manuals
As for those shopping, I've found it really handy when looking for
complex machinery (like a farm tractor, or planter) to acquire the
manual first, then when I shop after studying the manual I can know more
than the seller and exercise the equipment better before buying.
The HP 1740 manual is at:

Tek isn't as friendly without signing in with a serial number which
makes manual study before purchase difficult without PAYING for the
manual. There have been quite a number of scopes, lately mostly digital
since the 465 and 1740 were competing for the market. For RF work I
still prefer the analog scope because things don't often repeat for a
sampling scope that expects repetitive signals to grab properly.
There are probably tutorials available from Tek and HP/Agilent on use of
the analog scopes that go into detail on how to calibrate and how to
show waveforms.

Is the HP 1745 a good'un then? I have had a 1745, with two TEK P6131 10X
passive probes for a few years, but was unable to find a manual for it
when first
bought it, and have not tried for a while now. Never used a scope enough to
even know HOW to use one, but enjoy reading postings from you particularly,
along with a few of the other guys that seem to know what they are
talking about.
I have been a big fan of Ten Tec for a lotta years, and have a stable of
7 of their
rigs dating from the Omni VI Option 3, back thru the Triton IV digital.
I am also a
big fan of Elecraft, and built the K2 #317 and K3 # 833.
Appreciate your opinion on the 1745.
Thanks, 73 Dub K5DUB

If its not Tek or HP and if its HP before the 1740, its not really a
scope that works well and reliably. Yes there were pretenders but their
products tended to be poor with poor bandwidths and lousy sweep
triggering. The Tek 465 except for the delayed sweep switch and the HP
1740 or 1742 have been reliable tools that work well and are FLAT to
their bandwidth spec, not 3 dB down a the bandwidth spec. These are 200
MHz and most logic glitches will be seen by them. A 30 MHz scope can
miss glitches that logic can make. With my 475 on the bench I used it
for DC through UHF measurements and set the VTVM on the back test
equipment shelf. I quit using a meter with a GOOD DC scope available.
