Bjoern. & all others who responsed to my Question . Last weekend i finally got time to put the HP8563 on the workbench ... Adjusted the trimmer that Bjoern suggested and yes it came alive ... i

Hi There is no separate manual for the C version, the only one on the HP (now Keysight) web site covers all versions A through D, The only difference from A to D appears to be the frequency range

I am hoping that there are some HP652a owners out there that can tell me whether this is normal behavior or points to a problem with my particular 652a... In case you don't know.... Unlike the other

Yes it clicks when turning the amplitude knob... Regards

Hello George, thanks for your feedback so I?ll search in the reverse power protection. I don?t have a service manual for that one, but for a similar ( the A Version) 73 J. DJ4HW

As an HP-IB specialist supporting customers trying to interface non HP controllers to HP equipment brought out a particular requirement. At the end of each control to an HP-IB device, the string must

So I got it working! I think your last comment about terminating read on new line did it. In the configuration options in visual Basic: hp5335.io.Timeout() = 9000 hp5335.io.TerminationCharacter=&H0A '

Hi Josef This would, without further information, appear to be the result produced by accidentally transmitting into the signal generator. The 8648 range has a maximum reverse power tolerance of 25W

Orin, Thanks as always for the code. Still fails with a timeout. I tried various sleep times before issuing the read as well as longer timeout lengths. Your initialization code was the same as mine.

From the description, my first suggestion is to check the attenuator module. Does it click when scrolling through the range of attenuation values? hp_agilent_equipment@...> wrote: -- Colby

Hello, need some help. My good old 8648c will not set the amplitude even I set to -100 dbm or even to -20dm the output seems to be the same. The effect is the same with or without modulation The

Hi Jerry, The 5335A is rather fussy and will sulk at the slightest provocation. Here is a snippet of Win32 C++ code that worked for me with the Prologix Ethernet controller. I could send you the

I recently acquired an HP 5335 which seems to work fine except I can't get a GPIB reply out of it. I tried the code sequences in the manual. I can send commands that are correctly interpreted like

Damn, I say thanks David for the killing of that dog. I've got the LS and its a hot power pig X5 in the circuit. To your knowledge was there a sub or another like HC/HCT that can be designed in? Also

Cool but not always successful—for example, the SOS (Silicon on Saphire) process that was supposed to replace CMOS. Jeremy [hp_agilent_equipment] <hp_agilent_equipment@...> wrote:

Morning Guys, After days and days of net hunting this chip appears to be unobtainium. I was hoping to find replacements or newer versions. Nothing! This is a 24pin slim, 8 bit presettable tri-state
