Hi, I am looking for a schematic, or service manual with schematic, for the HP8648B. My set is faulty with these error codes : Opt 1E6. 100khz-2000Mhz. . Faults are : 516 Config 2 restore

Hi Jim, Do not unscrew the solenoids on the top, at least not for now. To see what's happening, you will have to open the lower part where the RF action is. The two SMA connectors have hex-nuts.

No. The DPO uses an LSI-11 as a 'puter. I have one. The 7D20 is much later. The DPO separated thye PI and display sections of the scope with a digitizer unit, maybe the d7001. Are you sure about the

Vladan- I got the cover off without trouble. By testing I note that when the middle (40 dB) switch is triggered, the output turns off completely. As far as I can determine, the plunger is actuated

Jim, You will have to pull out the front panel. There are a few flat-head screws along the front frame (top and bottom, maybe even sides - don't remember any more). Once you remove them, the front

All- When all else fails, read the manual! The 8568B service manual says to remove the front panel. That is easy and the attenuator is then right in front of you. I was trying to get at it from the

Hi Christian, There is very little information available about the firmware revisions for the 8970B. Certainly, if you have a standard unit (1600 MHz high end), you will not want any version of the

I have a Phillips PM3375 out in the workshop, and I'm using an HP54601A in the radio shack to monitor transmitter RF; with accurate directional couplers, I can calibrate watt meters. Not far away, on

All- O.k., I have an 8568B with a bad attenuator (40dB and below are dead). My big question is - how do you get access to the attenuator to take it apart and clean/repair? It seems to be really

I will admit that there is not a complete and free 2230 service manual available online but ArtekManuals and others have scanned service manuals available inexpensively. Maintenance is made easier

Back in the mid 80's I remember using the Tek 7D20 digitizer plug-in. It only had a 20MHz sampling rate with an over sampling bandwidth of 70MHz. It was OK for sampling in the audio range but not go

That's a new one on me.

The A3 Directional Bridge (Port 1) has a pair of toroids on each side. The pair with brown "wire" is wound with coax. Is the grey "wire" on the other pair also coax? I have an 85046A S parameter test

I've looked into the Tek 2230 before and found it's performance and ease of use is nowhere near the Fluke PM3390. It's also very hard to get detailed info of 2230. For Fluke PM3390, you can purchase a

Hi Vlandan, Thank you for your answer. Do you think version 8005x is compatible with all 8970B's? (including mine: S/N 2721Axxxx) Seems strange that this number is a five-digit where mine has a

Thanks for all this information. Certainly there are more options to consider than I thought there would be if it existed at all.

Hi Christian, I also see a newer version (standard, not Opt 020) there: http://ko4bb.com/Manuals/04)_ROM_Images_and_Drivers/HP_8970B/HP_8970B_08970_8005X.zip Vladan
