(OT?...) Sticky labels for aluminum and other typical materials panels
8
Hi all, I've had limited success (hand) writing, and sometimes printing, labels to stick on DIY project boxes for miscellaneous labeling needs. There was some chatter here on materials and printing means and solutions, but I'm really only looking for some recommendations for DIY projects. What types of sticky labels are better for these specific applications? What stays put and doesn't peel off the minute finger pressure gets lifted, or there's some variation in temperature and/or humidity? Or just the passage of... minutes. I've this far used "office supplies" types, but they'd always peel off in short order, and there must be affordable, easily accessible other options I'm not aware of. Apologies if this is far off topic - hopefully others will find it useful for their own needs. Thank you, Radu.

HP 8566B repair
Hello everyone. Suddenly my spectrum analyzer (HP 8566B) has the following problems: the low band signal is about 40 dB lower than it should be. The high band has stopped working: the various bands no longer appear on the screen, but a single band similar to the low band and the signal is completely absent! I strongly suspect that the YTX oscillator is dead or almost dead! Does anyone have any ideas about this? Thanks. Images: HP8566B and output at first LO connector.

HP 8594E option question

Hello Folks, sorry to annoy you with a problem - in an act of stupidity, I bought like half of a 8510C VNA. In particular, I got the display and the test set, which means I miss the compute unit and the waveform generator. A friend of mine would now have a 2602 serial number of the 8340A unit which he would want to offload onto me for a nice price. For me, the key question is whether this - it is quite an old version of the generator - will be compatible with the 8510C? I looked around the internet a bit, and so far did not find any binding answer... Tam -- With best regards Tam HANNA Enjoy electronics?

Dear Colleagues, Does anyone of you own an 85101C display unit with option 011 and would be able to download the contents of the PAL security key 08530-80004 (option for the 8530A microwave receiver). I have an 85101C display unit that I would like to use for antenna measurements, I have the operating system on a LIF floppy disk ready to reload, unfortunately my 85101C unit does not have option 011 (dual identity 8510C/8530A). I would be extremely grateful, I think that the contents of the PAL would be also valuable for other microwave hobbyists. Best regards, Wojciech

Keysight R8486D/Q8486D microwave transition power sensor question
4
This rf power sensor has a waveguide to TEM transition which then drives the more or less standard diode detector/chopper mechanism (I assume, never seen one). Does anybody know if there is a filter between the 50MHz ref connector and the transition? Keysight manual says nothing besides not being repairable. Another question is calibration. It needs a 30dB atten so the sensor cals at -30dBm, how does the display know about that?

HP 11683A Range Calibrator - Anyone ever swapped resistors for a repair?
5
Hey All, I dropped my 11683A Range Calibrator on the bench to test some 435A meters, and I've discovered that it is out of specification. Here is what I measured on the device: The lower level resistances are good, and my overall reference voltage is close to 15.8V (and can be adjusted to the 145mV as the manual specifies for the 1mW range). However, as you can see it fails the greater 1mW ranges, which I think indicates that there is a problem in the upper resistor array and this, again as far as I can tell, makes the voltage measurement stuff a bit dodgy. Does anyone have any recommendations on replacement resistors? The manual says a 0.1% with TC=0 +/- 10, the OEM was Micro-Ohm Corp of CA. Thanks, TonyG

Hi, does anybody happen to know which rear dip switch language setting belongs to which programming language? I could not find this in the manuals, probably simply not seeing it. Right now it is set to 001 which must be analyzer mode as it is running in an 8510C system. Which setting is SCPI language? Tom

HP/Agilent/Keysight VEE (OT?)

Hi Group. Not much found here (Groups.io) on this topic. Found a VEE 'program' that calibrates my E5071B ENA. I might have some issues/questions about it. Any other VEE users out there? Thanks in advance! Mark

Hi guys, as you all know, the HP 435A, 436A, 437A and so on are quite nice power meters and the meter itself is availabe at quite low prices. However, the power sensors are quite expensive. I own a 8481A and a 8484A, both in nice and working condition, but I don't want to damage anything so I treat them like raw eggs and handle them extremely careful. So I always thought whether it would be possible to make a own diode power sensor which is compatible to the HP 436A. This would have the advantage that the 436A could be used (and therefore its HPIB capabilities), and if it works with the 436A, it will do so also with the other meters (and possibly others, I don't know). Further, the homebrew power sensor would be cheap and if it breaks, no matter, it can be repaired easily. So today I spent a few hours on making my own power sensor. I checked the schematic of the 8481A power sensor, and I did basically the very same. I came up with this schematic: (I don't want to waste valueable web space for the group, so I uploaded the high resolution pictures to my webspace) https://hb9fsx.ch/wordpress/wp-content/uploads/2018/11/20181117_173101.jpg The letters on the right side are the connector pins for the HP 436A, of course. Then I made a quick 'dead bug' style prototype, as follows.... (please don't laugh at me :-) ). https://hb9fsx.ch/wordpress/wp-content/uploads/2018/11/20181117_170657.jpg I connected to the 436A and I also installed a SMA 30dB attenuator at the input and connected my power sensor to the power reference of the 436A. At first, the readings were quite off a bit, but using the little trim pot on my PCB, I was able to precisely adjust the gain of my sensor such that the reading on the power meter was exactly 0.00 dBm. I then connected a signal generator to the power sensor and tested various power levels between -10dBm and +20dBm. Incredible, but my power sensor was accurate to 0.1dB! I also tested different frequencies between 1MHz and 2.6GHz. The flatness was not extremely good, but between +/-1dB. So, basically, the concept seems to work. I also tested different ranges for the power sensor - there is a 'mount resistor' inside the HP power sensors (8481, 8482, 9494, ...) which tells the power meter which range the sensor uses; the meter then internally adjusts the gain according to the power sensor range. It appears that it should be possible to home brew such power sensors. However, at the moment, I have two issues: a) the auto zero function does not work - even if I run the autozero feature, the power meter afterwards displays -13dBm anyway, so I cannot properly zero my power sensor. At the moment, I do not understand why this is so. Has anyone on the list an idea? b) I don't understand exactly how the amplifier using the NPN transistor works. When I was adjusting the gain of my sensor, I tried to change the collector resistor (330 Ohms), but this had almost no effect on the gain. The emitter resistor (1k Ohms) also had only little effect on the gain. Only when I placed the pot where it is now I was able to adjust the gain in a wide range. So it basically looks to me like this amplifier is a common emitter amplifier, with the gain being RC / RE, is that true? why then is a feedback from the emitter required to the meter? Thanks for any hints, tips and so on, Tobias HB9FSX
