Re: 5350B - transmutation to a 5351B

 

The '52 has a different MW sampler (might be screened for upper frequencies) and a different input connector assembly.

Re: 5350B - transmutation to a 5351B

 

What are the hardware differences between the '51 and '52?

Thanks!

It does not have any options, has a TCXO ref. Guess the firmware don't need to know of option 006 and 010.

Hi Don,

?

The 5350/51/52 all use the same EPROM.

There are some dip-switches on the main board that set the different options.

?

I have a 5351B with a newer revision of the main board, 05350-60025, where this is selected by S1, next to the XA4B connector.

?

I have a photo of the inside, where I just barley?can see the switch settings, the switches is marked 1-7

I think this is the settings on my 5351, but can't be sure due to bad pohoto:? 1:0ff, 2:off, 3:off, 4:on, 5:off, 6:off, 7:on??

?

I see in the SM that the older 05350-60008 main board has jumpers instead of dip-switches. But numbering should be the same.

?

Another difference between the 50 and 51 is the input connector, its N on the 50, but 3.5mm on the 51.

Instructions to alter 5350/51B to a 5352B:

There¡¯s either a DIP Switch (S1 on the motherboard) or a set of jumpers right behind the processor board.

For the 5350B, the settings are positions 4 & 7

For the 5351/52 the settings are positions 4 & 5.? Otherwise the counter won¡¯t go past 26.5Ghz.

Opt.005 and 010?? -?? 46 GHz:
All are closed ecxept number 2 is open or up.

For those not familiar with him - and his company ArtekManuals - he provides at very fair prices PDF scans of various test equipment manuals.?

Re: 8350B (V7) - no ID command?

 

Hi.

There appears to be a full user manual here:-



Viewable online, but there are download options in various formats.

From a quick look, from page 3-37 onwards, this is an "old school"
instrument with a non IEEE488.2 or SCPI command set, so no *IDN? etc.

But there are a lot of things you can do with it, but the learning curve
is going to be steep if all you've used are later IEEE488.2 compliant
type instruments.

There is also a digital/analogue external programming port, where you
can control it with various unique digital and analogue signals.

"Enjoy!"

Re: Metrology Grade adapters - HP/Agilent 1250-1745 and 1250-1740 - insertion loss ?

 

Tim -

Assuming you mean 1250-1745 and -1750, these are both part of the 85033E/400 kit. Any published specifications are in that manual, downloadable from Keysight. They are only spec'd for mechanical dimensions and return loss, the latter of which is listed as a minimum of 28dB and 24dB from DC to 18Ghz for the -1745 and -1750, respectively. Therefore best case insertion loss is 0.01dB and 0.02dB, respectively. Actual insertion losses will be slightly higher due to losses in the adapters themselves not reflected. Can this be zeroed out using the calibrator on your power meter?

Hoping to verify... have my 8350B hooked into my HP-IB (GPIB) and apparently there is no "ID" command.
Have tried all possibilities used over the years and no mention in the manuals.

Seems odd that HP would not include it.
