The Bird 100W block attenuators come apart ok. Quite chunky though – not for hanging off a front panel! Colin Sent: 17 September 2021 17:54 To: [email protected] Subject:

jb or anyone, Have you ever seen a commercial attenuator that you could take apart (in the proper way without sawing or grinding)? So far I haven't. Hank __________________________________________

To take it one step further, you could make your own as long as you verify its operation in the frequency range you desire. I like the idea of cheap protection Instead of expensive and labor intensive

Alexandre, a DC block functions as a series capacitor in your input signal path. This keeps DC out, but being a capacitor, also has a response at RF that resembles a high pass filter. The cutoff

Dear sirs, I have a E8285A service monitor, and I know I can put no DC voltage on its inputs. So I have 3 questions: - Can I keep a DC blocker permanently connected to its inputs? - Is there a quality

The GBS8200/8220 does work without the sync separator but you lose part of the image. It's probably triggering on the wrong edge of the pulse or the first bit of video. I never bothered working out

is it possible to get a backup file of an 8920B made from x28c256 from you to do some testing? if possible thank you .

backing up the calibration EEPROM is always a good idea.? I typically do that when working on a unit. You can get a boot up checksum error from a couple of places. Usually if it's the cal data than a

ok thank you jeff, unfortunately my instrument is not equipped with rs232 and I have the problem to make it start. start problem is because it gives me checksum error and I have not understood why.?

Hi! Yes, you can do that pretty easily.That's what I did prior to begin thinkering with calibration data on my 8920A...At a first glance it is just a block of bytes, but when comparing the content of

hello, can someone tell me if the x28c256 memory installed on hp8920b can be copied with the programmer to have a .bin or .hex file to store it in case of failure. and if so, what results did it give?

After opening the other 40pin Epson 32k card that was HP branded, all I found was blobs of epoxy.? No joy. I did order out some 512k ultra low-power chips to try in the Agilent card, but is on the

Just a little more detailed description than was posted here before. Hank ______________________________________ There's a problem with dbm levels *only* in spectrum analyzer mode.? The 8920B

Thanks Hank. I'm sure there are members here with a lot of knowledge to help me. thank you for your support. Regards

Your English is fine. Maybe the temperature dependence and the screenshot you provided will give someone some clues as to where the problem lies. Hank

Dear Peter, I tried to clean all modules and all coax cables, but I wasn't successful, when HP8920B is on for 1 or 2 hours the failure is constant, but after 3 or 4 hours on, this failure becomes

Hi Alemao, After some time the rigid co-axial cables at the underside of the unit develop poor connections due to corrosion. they are very small and delicate but with care can be disconnected and

Hi I have got an intermittent error with my HP8920B. The error is "Receiver assembly (low)". Could someone please provide some clarity on this issue. Thanks in advance!

Thank you, Alexander, for your email. Pls note that as I wrote in my previous, in the next step I will try with a sync separator. But I think that reporting this easy way to get a picture to the
