Re: HP 436A
开云体育Brooke – ? Thanks for the info. The only problem is all three of my 436s behave the same way. What are the chances of all 3 having the same problem? Is there any one on here who does get a full 50 dB of dynamic range with their 436A? Did you try it Brooke? I just want to make sure it is me. I mentioned it to another friend of mine and he seemed to remember running into the same dilemma. 73 - Mike ? ? Mike B.

HP 436A
Hi Mike:
I asked a friend who's probably one of the world's experts on power measurements and he thinks you 436 is defective. His reply is: "Probably the A2 card (AC gain board, contains true range decoder) of the 436... might be the controller card A5 ... sends the range data to the A2."

Re: Digest Number 173
开云体育Brooke – ? For example, I can take any of my sensors, which are marked to have a 50 dB range and connect them to a signal generator. I start out with the maximum level indicated on the sensor and all is well. I go down 10 dB on the generator and the 436A follows, 10 more dB it still follows. Now, go 10 dB more and typically it goes under-range and no more reading. I just tried it using an 8484A which has a stated range of -20 dBm to -70 dBm. With -20 it is OK, -30 it is OK, -40 is OK, now I go to -50 and it just reads -4 indicating below range. Before applying power the readout showed a -7 indicating it properly detected the lowest range of the sensor. So, what’s up? Thanks - Mike ? ? Mike B.

HP 436A
开云体育I have a question regarding the subject power meter. According to all of the information I have, including catalogs and the manual, the instrument is supposed to be able to have a 50 dB dynamic range. Regardless of what sensor I use, or which of my 436As I use, I can only get a 30 dB dynamic range. What am I doing wrong? – Thanks - Mike ? ? Mike B.

RF Voltmeter HP 3406A
Gentlemen,
I have a HP 3406A Broadband Sampling Voltmeter I am repairing. According to the test procedure in the manual , the probe assembly is faulty and should be replaced as it is not field repairable. I doubt if these are available from HP and if they were one could not afford the price they would ask. Does anyone have any experience with fixing these probes? Failing this is there anyplace a replacement can be found. Thanks David David Hopkins (VK4ZF) Queensland AUSTRALIA davhop@... S 27, 22.294 E153, 11.008 |

Thanks George, I too have two of them ! the problem I have is that even with
the dip switch on the back set the same, one of them wont allow me to set the day/month, it increments ok as the clock cycles each day over, but wont allow me to reset and adjust the day/month like I can the other clock, I run one on UTC and the other local time, frustrating!
