Jerry:
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.
