Re: 85685A special cabling changes
Tim,
Yes, it is just straight-through and no termination (it's just the DC sweep signal, no RF). George ________________________________ From: Tim Hughes <timhughes@...> To: hp_agilent_equipment@...

Just splice a wire for the SMA connection to the wire going to pin 44. Cover the splice with heat shrink and mount the SMA connector on the connector hood that does not have the label. The SMA needs to point down so it does not interfer with the RF bus cable.

8690B in UK
I have an 8690B sweeper with an 8693A 3.5GHz to 6.75GHz plugin which I don't need and can't test (I don't have an SA). It is missing the tuning scale.
I would prefer that it went to a good home rather than the crusher, so I'm happy to let it go for a nominal charge (say GBP25?) However it will he horribly expensive to ship as it is large and weighs 33kg (about 73lb). I have been quoted about GBP60 JUST for shipping to a mainland UK address and packaging would be on top of that. For this reason you should be thinking in terms of picking it up from Kenilworth in the UK. If anyone is interested please let me know off line. This is the last call before I send it for scrap. Cheers David Partridge |

Re: HP 8563E spectrum analyser help needed
Hi,
The short may be a red Herring! Have you checked your 10Mhz reference? If you pull the A15 board out you should be able to get a reference board id eg.. 08590-60128 should give you a unique board reference.. I'll have a dig around and get back if I can.. Stuart..

Re: 5335A (was: counter)
Well, I bought two 5335A at a surplus store. One worked, and the other didn't. This latter turned out to have 4 (four) 22uF 35V shorted tantalums in the input module. Replaced the tantalums and fixed.

Looking for an WR90 wavegude spacer for homebrew X-band cal kit.
David Kirkby
I want to make some measurements in WR90 waveguide on a VNA. But since
it for amateur use (3 cm band) I can't justify buying an HP/Agilent X11644A calibration kit - even a used one. However, I believe I can make my own cal kit, good enough for this, from a load, short and an offset short, or more more easily from a load, short and a spacer+sjhort. I bought an HP load from eBay for $25, so that bit is solved, but I still need to make the short and offset short. I calculated a spacer of 9.5 mm would give me the ideal quarter wave (90 degree) delay at 10.25 GHz (centre of amateur band), but a couple of mm either side of that would be fine. Does anyone have anything suitable. I just want the standard flanges. Dave, G8WRB. |

Re: Sweeper Error Code E080
DAIPRA
Hi Cliff, to verify easily your YIG oscillator , there is an auxiliary
output at the rear of the plug-in if you do have a power meter , you can check the operating YIG connecting it to the Aux output , If you do have a microwave spectrum analyzer connect it to the Aux output, and during the test sweep ,(the entire range 10 MHz to 20 GHz) the YIG sweep from 2.3 GHz to 7GHz. I also have repaired an HP 8350B which give error code occasionally , the issue was on the mainframe connector J2 ,from the front view, J2 is on the right on the rear of the Mainframe, it is a CONEX plug which was corroded , the only way to repaired it ,as I do not have any parts, was to solder the wire directly on the pins on the mainframe. Truly yours. 73 from ON1EV Belgium De : hp_agilent_equipment@... [mailto:hp_agilent_equipment@...] De la part de g4bgp Envoy¨¦ : dimanche 17 mars 2013 14:50 ? : hp_agilent_equipment@...

HP 54001A Probe Output Connector
Hello, I have an HP 54001A 1GHz probe that I want to use as a general purpose probe. It's specifically designed to operate with the HP 54001A/D digitizing oscilloscope. I intend to build a suitable power supply with a receptacle to take the probe pod, supplying its power and taking the output signal via a cable with a BNC connector to plug into other test equipment. The probes output connector looks like an SMA connector without a thread to allow it to slide into the scope. I believe there are such things but it may be some other similar connector (SMB, SMC, etc.?). Can anyone tell me what this connector is and where I could get the mating connector please. There's an extender for servicing the probe which would be fine, except if there are any they are probably scarce, expensive and I'd rather leave any for their intended purpose for those who really need them. Any help gratefully received.
Thanks, Don Black. |

I have downloaded the Service manual from the Agilent site. I agree that there is scope for mis-reading the code.... But it really is E050, (or possibly E0B0). I did wonder, what happens if two error codes are displayed simutaneously. If that were possible then the result might be the binary addition of two or more codes.. any takers ?
