Re: hp8350b/hp83595a front panel mod
HP's provided tool kits to us (field engineering) also just had phillips. We learned if it's not torqued to tight a #2 phillips did OK on a #1 pozi. But the best answer is to buy the right ones even

Hi, Yep, me too, ever since I discovered this. I now feel the urge to buy some "for parts" old HP instrument for that one keycap :-) Szabolcs Raymond Domp Frank <hewpatek@...> ezt ¨ªrta

Re: hp8350b/hp83595a front panel mod
Notice those are PoziDriv head screws, not Phillips. It is easy to damage the screw head and possibly the driver by using the incorrect driver. We all should have 0, 1 and 2 PoziDriv screwdrivers!

Re: Service Support Software
Yes, I read on the HP site that the latest it supports is XP, but that was before WIN7 came out. Since I don't have an XP machine available, I thought I would give WIN7 a try. Tnx for the reply, 73,

I downloaded the Service Support Software package so I may try my hand at checking out my somewhat new 8648C Sig Gen. Upon opening the SW package up pops a window asking for a name and password. No

Good thing you put in the lower torque spec for 3.5 mm to SMA connection, Steve. I was about to recommend that the stainless steel SMA connectors be torqued to 8 in-lbs or 0.9 N-m (not N/m). I read

Re: GPSDO connected to external ref inputs
Thanks, Greg. I will put the 5087A on my wishlist! Nice that it allows individual output amplitudes to be set (how, though?) and that it has a large number of outputs. Although I couldn't find a

Re: HP 3325A Phase noise (and reference clock) as discussed in CuriousMarc's video of Soyuz Clock, Part 6
Yeah, the PTS generators are really, really good for PN, particularly at HF frequencies.

Re: HP 3325A Phase noise (and reference clock) as discussed in CuriousMarc's video of Soyuz Clock, Part 6
I agree. However, I do put the PTS stuff in a much higher category than the 3325A. Thanks ¨C Mike Mike B. Feher, N4FS 89 Arnold Blvd. Howell NJ 07731 848-245-9115

Re: HP 3325A Phase noise (and reference clock) as discussed in CuriousMarc's video of Soyuz Clock, Part 6
Trying to compare generators with all the variables that affect PN can drive you crazy, but would be worthwhile. I did tests on a bunch of PTS synthesizers and one of them included a comparison of

Re: HP 3325A Phase noise (and reference clock) as discussed in CuriousMarc's video of Soyuz Clock, Part 6
Very interesting John. Actually, I am surprised as to how good it is. Although, since the OCXO is also at 10 MHz, it would be more interesting to see it at some random frequency. Maybe as compared to
