Re: 1 mw - 0dbm lab calibration
Last year I acquired an HP 8485A thermistor sensor from Sphere as they closed down.? While this one works well, even up to 33 GHz, it lacks a calibration chart and instead has special markings shown

Re: 1 mw - 0dbm lab calibration
Hi Razvan Thanks! I hadn't seen AN215 so I'll give it a good read through. To be fair, I'm still not sure if the the 1830A is better than the N432A or the other way around. There isn't enough

Re: 1 mw - 0dbm lab calibration
I saw the video and they forgot one instrument in standby before starting the application which resulted in the failed demo. Strange that the application cannot recover from this state even after the

Re: 1 mw - 0dbm lab calibration
Hi Jeremy, Yes, you are right, it looks like the N432A is much better compared to the Tegam unit but you have to take in consideration also the price which is more than double for the Keysight one. I

Re: E4407B schematics
I bought the Artek manuals for the ESA spectrum analyzer and they were useless. The Tracking Generator is the older version in the manual and the RF deck is also different and my unit was built in

Re: (OT?...) Sticky labels for aluminum and other typical materials panels
Well, I don't know what the "Zia sun sign state" is, but in CO I lived at 6500' in a house that had maybe 70% fenestration. Without blinds and shades, the house was warm during the day. Even on days

Re: (OT?...) Sticky labels for aluminum and other typical materials panels
DAng! So brown and hanging down is coming with P-touch, eh? Big sun here in the Zia sun sign state. I've got about thirty labels on my akro mills drawers now. And room for 200 more. Maybe I'll look

Re: (OT?...) Sticky labels for aluminum and other typical materials panels
Also, P-touch label longevity depends on the ink color used. Black lasts a lot longer than red or blue. The white background browns over a period of a couple of years in strong sunlight. When I was in

Re: E4407B schematics
Keep in mind that there are at least TWO versions of the RF Deck board and the Artek manual only has the early version. Do not have the part numbers handy. Mark

Re: (OT?...) Sticky labels for aluminum and other typical materials panels
They probably have longer time since used for wiring labels. P-touch lasts maybe 7 years in sun, like vinyl lettering signs and most sign printing.

Re: (OT?...) Sticky labels for aluminum and other typical materials panels
I've used a great many of those labels for all sorts of stuff over the years. What you want to avoid is the ones labled "removable", they just don't stick all that well. If the ones you have don't
