Dan, I have a bunch of 6624s here. Later today I can pull one and use my thread figur-ma-thingie to see what size those may be. Radu. <dan.meeks222@...> wrote:

Hello Group - I got this 6624 quad power supply. All the screws in the four terminal strips were removed. M3 is too small, M4 is too big. 6-32 is about the right diameter but wrong thread. Anyone know

Hi James, I have several National Instruments PCI cards as well as a USB-GPIB. From Keysight, I have a PCI card, but also an 82357B that I bought about 3 years ago. I have used it very often since my

Just to throw one more hat in the ring, my newly-introduced Rev 2 of my KISS-488 adapter is a LOT cheaper, and handles USB/serial as well as Ethernet (both Telnet and HTTP). Its real claim to fame is

Hm, where are you getting that data? Keysight is selling new 82357B devices for $750. The NI adapters new are $1000+, depending on where you get them. If you’re referring to the new devices listed

Use Agilent 82357B adapters are similar in price to brand new NI devices. I'd prefer to use Agilent/HP generally, but also seem to recall reading that the Agilent devices are troublesome. Is that

Reminds me of my jet-like 8350. The fan pushed air through the power supply, then it split towards the electronics of the 8350 and further to the side where it went into the RF-modules. I made some

Dr. Dave,Have you tried contacting Maury Microwave.They have the 8550CK op manual and guide available for download. They may have a similar or equivalent manual available. Maury Microwave 8450P SC

Scott, I took a quick look at the video. HP rubber key pads had injection molded legends, which was done to prevent the numbers and letters from ever being wiped off either from use or solvent

Hi Mark, thanks for the link! I'll have a play with the keystroke emulation, seems straight forward. Hi Wilko, when I got my box, it only had flatness calibrated to 18GHz. So I had to do the

"CAL FETCH" and "CAL STORE" only load and store the self-cal data to/from NVRAM (e.g. results from CAL AMP and CAL FREQ). ?These are easily regenerated via self-cal if lost. ?If you are concerned

Write the cal constants down as the service manual instructs you to. The supercap that partners with the battery cell will power the SRAM while you are soldering in a new battery. I performed the

Coming via private email per above. I also found the service manual and saved text from another thread. Steve Hendrix

Hi Steve, yes, please send both, any bit of information is very welcome. Adapter is no problem, I have an NI and a Prologix and I can talk and listen via either. Please send to dg8saq (at) darc.de

Looking at the "Programmers Guide" I see CAL:FETCH and CAL:STORE commands. I also have a text file where I saved a thread about its flatness data over a year ago. I could send you either or both of

Hi Harke, my cal constants sit in a battery powered RAM. I had entered them manually a long time ago. I don't want to do that again after swapping the battery. There must be a way via GPIB. If someone

Tom, I do not know the 9x series but I am familiar with the 6x series. Does your analyzer have a EEPROM that you can copy? Btw: the RAM in need of a battery of the 61x series only contain less

Hi, does anybody happen to have a script or basic info how to read/restore the calibration constants via GPIB for the HP859x spectrum analyzers? My battery is nearing end of life... Thanks, Tom

OK, I found it, blue shift + presel peak. Unfortunately, the analyzer will really need adjustment because the problem has returned. In addition, the amplitude characteristic is wavy. However, I think

Don't forget it's not just about the power rating and cfm. Some of the older HP gear, especially RF gear, requires a certain static pressure from the fan in order to push air through the various
