Re: Manual for HP 466A amplifier
I don't mind getting it scanned at the museum, but does it still make sense to do that after the revelation that Artek has it available? I hadn't checked before; I had assumed the OP had already

I've got one of those amps and would like the schematic also. -- John Griessen

Re: Service manual scan post processing
While we seem to all agree that JPEG compression is not ideal, there ARE lossless options for TIFF and thus PDF formats.? While yes, storage and networking and processing and scanning time is all

Re: HP 3403C True RMS Voltmeter display fault
Yes, that's why I wanted to see a picture. I've never seen the ball-of-molten-tantalum failure on anything other than a dipped unit. Seconded. -Dave -- Dave McGuire, AK4HZ New

Re: HP 3403C True RMS Voltmeter display fault
The manual on the web gives type 150D for C1 & C2 on A7, these are hermetic sealed solid tants, of course they might have been replaced with a bead or the disguised bead in an axial or radial block

Re: E5052A Power On Test (3.3V Bus Supply)
I don't know if this helps, but I dug out the most recent Keysight calibration certificate for this E5052A and there is a noise floor test done at 70 MHz with correlation set to 1. I'm not sure what

Re: E5052A Power On Test (3.3V Bus Supply)
-120dBc/Hz at 1 Hz is way better than anything I've experienced. I had a look at a plot of my homebrew oscillator and it managed -116dBc/Hz at 10 Hz.? Pretty lame by comparison... I guess you are

On TP20 I have a RF signal is at 39.280 MHz, -1.3 dBm ?for frequency <16 MHz instead of 39,996 MHz ?--> Delta is 716 KHz On TP14 for a 10MHz setting on the VNA I have a 2sd LO frequency at 10.720

Re: E5052A Power On Test (3.3V Bus Supply)
Hi Leo This E5052A is quite old now and it does have a few internal spurious terms. Also the noise floor performance isn't that great even down at 10 MHz. I don't have any oscillators here that can

Re: HP Agilent 8753ES VNA repair [Help]
Hello Yves, Thank you for your last post. My VCO frequencies in TP20 *are not correct*. I have : - a RF signal is at 39.100 MHz, -1.3 dBm instead of 39.840 on your board for frequency >16 MHz - a RF

Re: HP Agilent 8753ES VNA repair [Help]
There are contradictions in the test results: If you say that the VCO frequencies are correct (39.996MHz for LOW and 39.84Mz for HIGH), then this necessarily means that the VCXO is at precisely 40
