Re: Introduction

 

Hi Robert,

I have two HP scopes. One is a 130C, which I will probably keep, at least for now. The other is a 140A with 1405A and 1420A plug ins. I will sell the 140A but at this time I have no idea what condition it is in, either cosmetically or functionally. If you are interested in the 140A let me know and I will check it out and get back to you.

I also have an 851B Spectrum Analyzer Display, but I only have the display, not the rest of the unit. I will probably scrap the 851B for parts so if you need any knobs or other scope parts contained in the display unit I might be able to help you.

With best wishes,

Jack

Greetings All,
I am a new member of the group and am looking forward to an enjoyable
time here.
I have a large inventory of HP boat anchors which I want to dispose of.
Some I want to sell as functional units, others might get parted out if
there is any market for these parts. There are over 60 units consisting
of these models: 130C, 140A, 1900A, 200CD, 214A, 302B, 342A, 400D,
400H,
411A, 415B, 428A, 431B, 5210A, 523C, 606A, 608C, 608D, 612A, 614A,
616A,
618B, 626A, 694A, 851B, 8690A, and probably a few others.
Any suggestions for disposing of this would be appreciated. I also need
manuals for most models and there are just too many to buy them. I
think
that there are downloadable manuals for the equivalent military units
but I don't know the military model numbers. Is there a cross reference
list available?
Thanks,
Jack

hp 5100A /5110A synth set

morriso2002
 

Hi all,

I'm new to this group, but not so new to vintage HP and other test
equipment. I'm sure there are a few familar names here!

I have recently found a nice clean 5100A/5110A synthesizer set and
would like to get it up & running.
I tried the 5110A and found two problems:

1. The 1 MHz output is fine but none of the other outputs are there

2. The oven temp meter reading just keeps getting higher & higher
till the meter goes off scale...obviously I have not left it in
standby mode!

Help! I really need some advice and especially a set of manuals. I am
located in Melbourne Australia and would be happy to pay for copying
& postage costs if anyone can help.

Thanks,

Morris Odell

HP 3310A Function Generator - Problem

David Jarman
 

I managed to switch off and on my trusty HP 3310A yesterday while it
was connected to an audio system (not good practise!) and it now
refuses to generate a signal from the low/high outputs. The mains
indicator light comes on and the fuse appears OK.

I don't have a circuit diagram. Can anyone help me to get my 3310A
operational again please?

Thanks in anticipation.

David Jarman
follow-up - HP 3439A

computeruser04
 

The HP 3439A has been repaired. It was C8 on A9 that had failed.
I then zeroed the readout it using a calibration procedure found at
.
Thanks to everyone who replied. I also have a service manual
on the way to me from Joe VE7LBI.

Question - I zero the readout after a 30minute warmup. All ranges
read 0000 with the + & - flashing alternately. The Int Check -8000
is also set per the precedure. It will stay like that (zeroed) all
day. If I turn it off then back on the next day - the zero
calibration is off - not by much - sometimes +0001 or -0002. I can
zero it again - and it will stay like that all day. Is this normal
or am I being anal about a +35 year old instrument?

Thank
BL

Robin,

I have bunches of HP manuals, at: .

For the 1740A, it loos like all I have is the operator's guides, not a service manual.

I think ONE of the ones that I have might also be downloadable from agilent.com .


Good luck!

I am interested in the manual if it is a service manual with
a schematic. You say it is the same as the 3449 (typo?)
Is it the same as the 3439 except for the sampe rate?
If so I am interested. leave me an email or web address

Did you check all supply voltages for ripple?

Ripple is about 1.5v on the 150v supplies and about .5v on the 50v
supply. This site:
has the calibration procedure for the 3439A which gave me some more
good information.
This site: mentions the
3440A which is very similar and their unit has the same symptoms:
"The nixie tubes light up, but multiple segments are on
simultaneously" so I am thinking this problem is common on these
units. Thanks for the replies so far.

I don't know if it will make you feel any better but I have a Fairchild Model 7000, 5 1/2 digit Nixie tube?DMM? and I use it all the time.? Works perfect.? I also have a Systron Donner 6152A, 500 mHz Nixie freq. counter and it also works perfect.? I love Nixies -no reading glasses required!? The pinnacle of display technology, IMHO, ?was planar gas.? LCD displays were the downfall of modern electronics- screw low power consumption!?
