[R-390] My Bobbsey Twins

[jgedde at optonline.net]

Hiya Don,

Just a quick run-down of my bench equipment as requested:

Power Designs  TW500T Twin 0-50V Power Supply
Bio-Rad 0-500V DC Power Supply
Rigol DP832 Triple Power Supply
Sorensen DCS33-33 0-33V/33A Power Supply
Micronta Dual 15V power supply
Keithley 2015-P Audio Analyzing DMM
HP 3466A DMM
HP 3478A DMM
Brymen BM869S DMM
Fluke 110 DMM
Simpson 260
Misc assorted low end DMMs
NRI Model 70 Tube Tester
Agilent 53131A Frequency Counter with 3.2 GHz option
Rigol DG1022U Function/Arb Generator
Rigol DS1102Z Scope
Tek 2465 Scope
Siglent SSA3021X Spectrum Analyzer
HP 8644A Sig Gen
BG7TBL 10 MHz GPS Disciplined Frequency Standard (GPSDO)
BG7TBL 10 MHz Distribution Amplifier

I am an electronics engineer by trade and do a lot of side-work in my home
lab so many of these pieces are a business need.

The 10 MHz standards are connected to my frequency counter, spectrum
analyzer, RF sig gen, etc. and keep everything locked to a single, very
accurate frequency standard (something like 40 parts per trillion)

The microscope is an absolute necessity since my eyes are no longer anywhere
near as good as they once were.  I need that for all but the largest SMT
stuff.  

John

Nice work, John.  You can be proud of either standalone or both side by
side.

I'm interested in the rundown on your workbench test equipment - looks like
some high end modern goodies residing above your twins.   And an inspection
scope to boot.   I do so appreciate the contrast, some might say irony, of
a high end modern workbench used to service and restore classic radio
receivers.  Its in the category of  "nothing is too good for our babies".

In fact, I would find it interesting what modern test gear list members use
and swear by, just for list members who are getting started putting together
a service bench or or upgrading.  We are always upgrading, aren't we?  I'm
in the process of restoring a Fluke 8842A DVM.  Not a modern meter by any
means but better than most of the other older Flukes and HPs on my bench.
And like my collection of R-390 gear, I need to downsize the older heavier
larger test equipment on my sagging workbench.  Looking for a replacement
for my HP-8640 sig gen.

Don
