Re: HP 85047A (S-param test set) with loose Port1
Dave is correct. I did not know this and checked port 1 on my 85046B and indeed it moves a bit. Jos PA0AMX

Re: HP 85047A (S-param test set) with loose Port1
Hi, Thanks both for the reassurance, So it looks like it was designed to do that then. The sensor connector is very slightly bent. I did power the unit up and using a signal generator, power meter and

Re: HP 85047A (S-param test set) with loose Port1
Charles, One of the ports on my 8503 S param test set moved, and yes it was the one with the plastic washers on it. It drove me mad so I simply turned the washers upside down and tightened the screws

Re: HP 83592B hangs 8350B sweeper
Hi, Try a burst of aerosol Contact Cleaner on the contacts on the back of the plugin also on the mating connector inside the mainframe. In my experience that seems to suppress the error messages that

HP 85047A (S-param test set) with loose Port1
Hi, A while ago I managed to acquire a HP 85047A, unfortunately it has had an accident sometime in it's life and Port1 is loose and slightly bent. I have measured the directivity of the port and it

Re: HP 83592B hangs 8350B sweeper
As an addition, you have removed your nicad battery pack, right? The nicad pack in the 8350B main frame, when overcharged (which is always) vents caustic fumes and they fume all over the plugin, and

Re: HP 83592B hangs 8350B sweeper
I'd immediately suspect a shorted tantalum capacitor on one of the supply lines. I had one with nearly-identical symptoms a few years ago, and that was the cause. -Dave -- Dave McGuire, AK4HZ New

HP 83592B hangs 8350B sweeper
My 8350B with 83592B plug-in turns on with flickering displays that go blank and hangs the 8350B with no error message, and no response to any switches on either the plug-in or mainframe. While

In addition to what Alan writes: - have a look at the program and see if the array that V(N,2) is an element of, is declared as an integer array. If so, any fractions added to x(1,1) will be lost by

Re: alternatives to 54120b test set
54123a - 34 ghz 54121a - 20 ghz 54121a - 12.5 ghz ?I think that's accurate. I've seen test sets, not saying which one (likely the 54121a though) for around 100$. An anomaly? Perhaps, but deals can be

That's an achievable price for a 54121A. Here's one that went for $105 + ship: http://www.ebay.com/itm/HP-AGILENT-54121A-4-CHANNEL-TEST-SET-/252046177093

I will give that a try on Monday. I might be able to tell the DVM to do some math too - but I think that slows down the output.

Re: alternatives to 54120b test set
Looking at Block Diagram of 4 Channel Test Set for 54120 Mainframe shows it contains Horizontal (A1) and Vertical (A2) Assembly. Where did you see a 4 Channel test set for under $100? Dennis

Re: I need a SINT value!
You are getting it! but in integer arithmetic. If you convert to floating point at that part of the program you will will most probably get the same result. You need to do division arithmetic before
