I thought we were supposed to do the deep cleaning in the spring?
I found more stuff to part with. This time, it's test equipment. All of it
as a matter of fact. I'm going to consolidate and upgrade my stuff but need
to liquidate what I've got before the XYL decides to do some liquidating
too!
My hope is to dump the whole pile into somebody's pickup/van. One stack of
greenbacks for a very large pile of decent test equipment. It's a
tinkerer's dream or an eBayer's Eldorado (as in Voltaire's land of solid
gold)! Keep what you want and peddle the rest. Some of the equipment is
mounted on Homebrewed 19" racks on wheels. There are 2 racks holding spec
analyzers/sweepers/generators/powersupplies/etc. Each rack is about 4' high
and has a shelf on the top to sport a scope, or DUT, etc.
I'm not looking for absolute top dollar on this stuff. As a package, I'd
expect to get a significant fraction (60%-75%) of eBay prices (excluding
shipping of course). Don't even bother me with offers to cherry pick the
list. I want it to go as a package--all of it. Most of this stuff is
easily valued on eBay "completed auctions" and don't want to deal with
moving the good stuff by next weekend and then have to haul, push, peddle,
shove, store, give, beg, and eventually dumpster the last few pieces.
Bottom line is that I've been collecting this stuff for 20 years. Much of
it came from TRW in california. I'll help load it into the vehicle of the
first person that can convince me their offer is fair. I can send some
pictures but interested persons should plan on coming to visit/test/ponder
the pile. It's my whole lab and to my knowledge the vast majority of it
works well. You can come and test or check out what you want before you
make an offer. I live about 50 minutes west of Ridgedale on Highway 12.
SCOPES:
---------------------------------------
Tektronix 7704A 4-bay scope mainframe (400MHz)
Tektronix 7603 3-bay scope mainframe (250MHz)
HP-181 Parts unit
Both of these are on a cart.
Plug-ins for above scopes--mix and match as needed...
7A16A single channel vertical 250MHz
7A16A single channel vertical 250MHz
7A24 Dual channel vertical 100Mhz
7B92A Dual Timebase (Triggered) with max resolution of 0.5nS/div
7B80 Single Timebase (Triggered) with max resolution of 10nS/div
7B53 Dual Timebase (Triggered) with max resolution of 0.5uS/div
7D20 Dual channel (3-bay) digital plug-in with storage (75MHz bandwidth)
includes manual
Before you get all warm-and-fuzzy about the 400MHz frame, remember, a 400MHz
frame with a 125MHz plug-in is about 100MHz of bandwidth. Likewise, a
400MHz frame with a 400Mhz plug-in is about 250MHz effective bandwidth.
These are all solid-state scopes. Mix and match the plug-ins as needed. I
thought I had a differential Vert amp plug-in too but must have loaned it
out--permanently apparently. Maybe one of you guys borrowed it and can fork
it over!
500MHz Probe
---------------------------------------
HP Model 1120A
DC coupled to >500Mhz
AC coupled 1.5kHz to >500MHz
Pulse response <0.75nS
Includes a remote Power Supply for those scopes not already equipped for a
probe
Included with original HP Plastic carrying case and manual
SPECTRUM ANALYZERS
---------------------------------------
HP-141T (works well) (square scope w/storage)
HP-141S (works well) (same as above but older round scope w/persistance)
Plug-ins:
8552A IF
8552A IF
8552B IF (rough but complete)
8552A IF
8553B RF 0-11MHz and 0-110MHz
8553B RF 0-11MHz and 0-110MHz
8554L RF 0-1200MHz
8555A RF 0-43GHz in 14 bands
0-2GHz
2-7GHz
2.6-4GHz
1.5-3.5GHz
4.1-11GHz
4.1-7GHz
6.2-15GHz
6.2-11GHz
10-23GHz
8.2-15GHz
10.4-19GHz
22.6-43GHz (good luck with the waveguide to BNC adapter hihi)
18.6-39GHz
14.4-27GHz
I have the very rare adapter for the HP141T to attach a preselector. The
141S cannot handle the preselector. Very nice.
HP141T manual included, some plug-in manuals too
The frames are quite low frequency (5 MHz?). Calibrating the frames
requires the use of traditional scope plug-ins for vertical and horizontal
sweep. I have 4 scope plug-ins for calibrating the mainframes and will be
included with the package.
WIDEBAND AMPLIFIER
---------------------------------------
HP-461A has 2 ports "IN" and "OUT" marked 50 ohms.
Frequency range is 1KHz to 150MHz
A 3 position switch has "OFF" which is not "Bypass", +20dB and +40dB
Insert the amplifier into any signal stream and you can add 20dB or 40dB.
Response is flat from near-DC through well over 2M.
SIGNAL GENERATOR
---------------------------------------
Singer SG-1000 digital signal generator w/manual. This has a calibrated
output (both frequency and amplitude).
6 bands resolution
7.75-16MHz 100Hz
15.5-32MHz 1KHz
31-64MHz 1KHz
62-126MHz 1KHz
124-256MHz 10KHz
248-512MHz 10KHz
Residual FM 0.25ppm peak
Drift 110ppm/10 minutes after 2 hour warmup
Spurs <-30dBc
Subharmonics <-40dBc
CW, FM, Pulse and Video +20dBm to -146dBm
SIGNAL GENERATOR
---------------------------------------
HP-608C 10-480MHz signal generator. 50ohm output.
It has a video input but generally I just use it in CW mode.
Calibrated output (analog dial) from +6dBm to -130dBm
Output is calibrated for each frequency. Not good for sweep tests.
Stability is good after warmup but not brilliant on VHF / UHF but very
usable for calibration and testing. At 2M I recall listening to a CW note
sweep the passband in several minutes. Not bad for the vintage.
HP-608C same as above but low output (parts unit)
SIGNAL GENERATOR
---------------------------------------
HP-606 Rack mounted 50KHz to 65MHz in 6 bands 50 ohm output
Output level is calibrated in detents of 10dB starting at +20dBm down to
-110dBm.
Fairly stable frequency after warmup.
HP-606 (bench-top cabinet w/handles) Works well as far as RF goes but has
some AC hum and FMs a bit.
This is not my generator but believe it to be for sale too.
0.8GHz to 2.4GHz SIGNAL GENERATOR
---------------------------------------
HP-8614A w/calibrated amplitude output
~+10dBm to -130dBm with digital attenuation
ALC, video, etc.
VARIABLE RF ATTENUATION PAD
---------------------------------------
HP-394A -120dB to -6dB variable pad
Dial looks like a HP608 pad dial. (6" x 12" x 3")
Indicates 1000-2000MHz but I've used it for accurate readings to low HF
4 Ports:
Input
Unattenuated output
Termination
Attenuated Output
If you terminate the unit into 50 ohms, you can accurately measure QRO
levels with low power meters/scopes/etc.
SWEEP OSCILATOR
---------------------------------------
HP-8690B Sweeper w/2 plug-ins
HP-8698B 1 to 110MHz w/x0.1 for 0.1MHz to 11MHz band
Detent attenuator with detents at +13dBm, +10dBm, and every -10dB to -100dBm
HP-8699B 0.1GHz to 4GHz in 2 bands
Band 1: 2GHz to 4GHz
Band 2: 0.1GHz to 4GHz
Output not calibrated but level and variable
FUNCTION GENERATOR
---------------------------------------
HP-3300A Function generator
Sine, square, triangle (dual output)
Max Freq (1MHz?)
Sweeper plug-in (start-stop, etc.)
FREQUENCY COUNTER
---------------------------------------
HP-5305B 1300MHz Counter using the "HP5300B Measuring System"
Battery pack w/dead batts for portable operation if repaired
0.1Hz resolution
X1000 resolution up to 10KHz
Two ranges:
0-100MHz (1M ohm input)
90-1300MHz (50 ohm input)
FREQUENCY COUNTER
---------------------------------------
Syster/Donner Model 6057
Two ranges
0-200MHz (high impedance)
200MHz to 18GHz (50 ohms)
Resolution (1Hz)
The high range is irradic but no-doubt repairable
POWER METERS
---------------------------------------
Calibrated power meters
HP-431B (meter only)
HP-431C (complete w/thermistor and manual)
7 ranges
10, 30, 100, and 300uW.
1, 3, and 10mW
Calibrated in dBm from -20dBm to +10dBm in 5dB steps
CALIBRATION UNIT
---------------------------------------
Fluke 5100B calibrated voltage/frequency unit
Why send out to the lab for calibration? Using this unit and go into the
calibration business too! This includes several options that are quite
valuable. One is the GPIB option. High voltage (multiple KV), and High
Frequency (10MHz?)
LAB SUPPLY
---------------------------------------
HP-6433B 0-36vdc, 0-10Amp
This is a regulated rack mounted supply (~6" high) with full metering of
volts and amps.
Current limiting is adjustable from 0-10Amps.
LAB SUPPLY
---------------------------------------
Lab supply on steroids actually--very heavy duty.
Lambda Regulated Rack Mounted DC Supply MO# LE107M
0-18V, 0-22Amp
Voltage and Amp analog meters on front
No manual
