Joel, I have been following the troubleshooting tr

I found an HP58503A GPSDO locally, with a faulty psu, but very cheap (?50). The PSU is a quick repair, using a Meanwell PT-65S (5V/1A, +/-15V 0.5A) Unfortunately my version had RevC "Option H14",

Ok, then I'd suggest we focus on getting the oscillator running again ! Since it used to be OK, you may want to start by looking for any broken wires, etc ... Maybe it's just a broken wire. The

Yes, I've done exactly this, minus the PC. I threw together a simple stepper controller, got a cheap stepper-driven rotary table, and tied it into my 8530A. It worked fine, though I'd really like to

After replacing the resistor all seems okay in that area.? No other failures.? Just a bad resistor that went up in value and then overheated. The latest is that a new failure has surfaced.? Now the

Hi Andy, I asssume you sorted this out after all this time, but if not, I can send you the wiring details. And it's just a very ordinary PSU.? 5V 1A and +/-15V 0.5A. Look on EEVBLOG and you will find

I've been studying the Agilent 85301B/C configuration guide, 5967-6042E, with the aim of being able to set up an automated anechoic test range for the 2.4 & 5 GHz ISM bands. My 8530A does not have

OK, this is getting ridiculous. Now it's "working" again. Almost makes me think there's something mechanical going on too. I hate finding mechanical issues...I have a Tek 7104 that had the resistor in

I think that something else has broken...the C function was somewhat functional before, and now it is not. Both C and L, the needle remains below zero scale and there is no oscillator activity.

Couple of further notes: - The signal at A1TP1/A1Q2 emitter disappears entirely in L or C - The frequency does not change no matter what range we're on - The signal actually is correct at 70 mVrms...I

Joel, 1) no worries 2) OK, I'm not sure how I didn't put 2+2 together on that but it makes perfect sense now. The 427A has a log scaled resistance scale! 3) A1TP1/A1Q2 emitter (in R mode, with a 1K

by the way, later you can download the V4.3 and V4.5 from Tony G depository (above) and update the software first to 4.3 and then to 4.5 for that you simply need to connect that CD drive to the IDE

+1 for Amirb's suggestion of a CF IDE adaptor. I've done this on a number of instruments. Robert G8RPI.

Hi Rik, That is because the format that they use for storing the likely compressed data is their own proprietary format. dd can backup/copy a full disk, or a partition, or a file, it doesn't care. It

A ghost image is a backup (full disk or only the partition) made by Norton ghost a DOS later Windows application (Norton later Symantic), it uses a proprietary technology to back up the disk. You

dd simply copies the disk exactly as the data appears on the drive. It is used in forensics to clone drives from crime scenes as it makes an exact copy down to the partition tables, and bad block
