Hi Paul,
?
The battery in my 70004A has axial leads and is
soldered in. It is also in a clip. Maybe they did different types?
?

If anyone has a switch actuator cable, please contact me off list.
I finally opened the display to see why it always stayed on, surprise,
no cable. I have no need for this display if anyone is interested before
it hits ebay.

Re: Front dust cover for 8920A/B?
Thanks, Jeff. I figured Rick might have them, but I just never contacted him.
He a few of them in stock and one should be on its way to me soon.
Thank you to everyone for your help!

Was there ever any kind of snap-on dust cover for the front

service monitor? Something to protect the front of the device during
transport?
If so, any idea where I might find one?
Thank you.

In mine, the battery is a Tadiran AA 3.6 volt with
axial wire leads. Here is one source. This is also the same battery used in the
70900A/B and also other 70k modules so buy a few if you are into the 70k series
instruments.

WE have the schematics/CLIP for the 70004A but there is no
schematic for the A3 display section proper . This usually implies that the
display was originally a3rd party drop in and not a Agilent design
The
Service Guide refers to the battery being on the A5 board and elsewhere talks
about a red LED error light relating to a battery failure. But I did not see a
part number for the battery, there is a crude drawing showing the location on
page 4-10 in the service guide.

If my memory is correct, the color display is from Sony, probably the same one that was used in some of the 8753 VNAs.

The copy of the service manual for the Marconi 2610 hosted at Didier's

Does anyone have a soft or hard copy of the complete service manual for this
fine instrument.

One thing i want to point out here is that the 70905 RF Section does not contain a preselector which makes it a pain in the ass to use, HP made a separate preselector module ( 70600A) but the better way is to find a 70908A or 70909A RF Section but you have to check the FW of your 900A to make sure its compatible !
The battery is a lithium battery about the size of a AA battery ,? its on the CPU board in the 70900A ,? when you open the lid of the 900 you see the CPU board on the outside , its easy to identify because it contains a little daughter board which holds the RAM and Firmware !
for manuals you can go to

I'll add, that outside of the shipping costs, 70004as are generally cheap. I paid <$150 for each of mine.
You can also hang an external display off of an 70004a.

Yes, a front cover was standard. The cover has a small hinged-door storage
compartment on the inside for power cord, test cables, etc.
I'm sure Rick at Amtronix has extras, he buys/sells/repairs a lot of the

Hi Walter
I am new to the 70000 equipment but lets
see if we can help
?
Firstly there is a battery in the 70004A
colour display and one in the 70900A LO
?
Regarding memory cards apparently available but expensive the question
is why do you require the memory ?
As the testing will not be to arduous with your current set up
?
The monitor is getting dim? the fix is to replace it with an
LCD? Look at newscope? 7A
This is a new product so I haven’t tried it yet but it comes from
a supplier with an excellent reputation
Of well engineered LCD replacement kits for HP equipment ,
?
Disassembly :- Strongly ?suggest you down load the 70004A op
manual? and the newscope? 7A manual
?
Extender units are like rocking horse droppings ?but do not despair?
you? have 70004A
You require a 700001 frame and 2 cables , you can make the cables your sylph
?
I have taken the covers of my 70004A and with this connected to a 70001
frame
I can work on the 70900A LO in the 70004A with the remaining modules in
the 70001 frame
?
Once you have the 70001 frame I suggest you get the preselected in put
for the 70905A
And a 70903A? 100Kc to 3 Mhz IF filter
?
Regards Paul B

There is a battery internal to the ?900a (on the CPU board iirc). ?Pretty easy to replace but it takes a soldering iron and you'll need to order the battery unless you have a well stocked battery collection.?
I can dig out the gory details when I get home.?
