Re: Storage Cap Ripple
Regarding the Off-Lock YTO loop, I suggest you to look at C7 on A20. This capacitor is known to go dry and create the ugly YTO unlock problem. A nice gentlemen create a YouTube video about this

Re: HP 1727A CRO: Problem with the vertical output amplifier.
Thanks for the suggestions, I will look into it further. I should have mentioned that the vertical deflection amplitude is off, as displayed on the screen. I don't know weather that is because of an

Re: HP 8594E upgrade CRT to LCD
Stuart not to throw stones. But I have seen a fair number of tek lcd displays that have gone to heck. Normally something like crystal leakage. (I just made that up). I can think of things like the tek

Re: eCal & HP-8753E
According to the compatibility matrix ONLY 85090 series ECAL are supported by the 8753 series analyzers , the N469X kits can be used however with the 8719/20/22 series but in any instance the 85097B

Re: eCal & HP-8753E
The 8753e should also work with some newer ECAL units(such as the n4691a/b) but finding the unique cable they require is tough. I was not able to locate one when I was searching.

Re: eCal & HP-8753E
the E will work just as well as the ES/ET and even the D will work but the D only works if you have the flash based CPU board , in any case the analyzer must have FW 7.68 or higher

Re: eCal & HP-8753E
I just looked it up and your 8753 needs FW 7.68 or higher for the ECAL to work as well as the 85097B PC interface , only 85090 series ECAL are supported

Re: eCal & HP-8753E
no , the older VNA required the use of either a 85060C controller or a 85097A PC interface ,? there were also some FW requirements on the 8753 as far as i remember on a side note i want to caution

Re: HP 1727A CRO: Problem with the vertical output amplifier.
----------------- Most likely U1 is good. You have one Vbe drop from pins 3/6 to pins 4/5 which is correct and collectors at pins 12/13 are balanced. In the plots you attached I thought there was an

Re: Storage Cap Ripple
Just keeping the 8566B in good condition in case I want to sell it. But it's a good point - my Trimble GPSDO probably has pretty good phase noise and I probably could use it as the reference for the

Re: HP 8594E upgrade CRT to LCD
Beautiful story. I avoid buying any equipment with CRT displays.? When I got my IFR 1600 service monitor, I got the version with LCD rather than CRT; 6 pounds lighter and the display will outlast me.

Re: eCal & HP-8753E
Get an 85097 as others have mentioned. An ECAL is totally worth it. I used them with my 8753e when I had it. I actually still have the 85097 and cables if you're interested.
