Re: Off Topic - Looking for assistance with power sensors
Hi, I will check my notes. I remember there were some GPIB DIAG and INIT commands that are not documented. If you look at the PS-Cal and SureCal calibration software you will see they can read/write

Re: Off Topic - Looking for assistance with power sensors
Of course, I would be very interested in knowing the solution for writing to R&S NRV-ZXX series sensors, as the documentation I've read doesn't mention it. It seems that specific software is required

Re: Off Topic - Looking for assistance with power sensors
According to HPAK's technical documentation, it's impossible to write new calibration factors into the sensor because each time it requires calculating a checksum that the EPMs of the E4416/17/18/19

Re: Off Topic - Looking for assistance with power sensors
Hello Mike, You need to use some power meter GPIB commands to write/update the sensor EEPROM. It is not only the calibration table coefficients to update but also the temperature compensation table. I

Re: BNC that does not have the bayonet lugs
This version of BNC is commonly used in avionics: Radios, Transponders and the like. The RF unit slides into a housing (tray); The (modified BNC Female) coax connector on the RF unit makes contact

Off Topic - Looking for assistance with power sensors
Hello again, I am hoping to find someone here who has done some work with the E44XX series of power sensors - specifically validating and recording the new cal factors to the EEPROM. Likewise for

Re: BNC that does not have the bayonet lugs
It would help if you told us what it is on. It does sound like the BWD powerscope connector. They will take a BNC but it won't lock on. Robert

Re: HP 334A distortion analyser problem
I think it's more likely that the problem is one or more electrolytic capacitors which often tend to be "leaky" when they are first charged up. This will go away after a bit of time.? If the required

Re: HP 8566B repair
I tried to start the automatic calibration routine (Shift W): the photos show the results obtained... I don't understand what "Recall: reg 7" means. ..

Re: HP 334A distortion analyser problem
Thank you for the input, you gave me new perspective. I was focused on the metering circuit, and when I applied freeze spray to the transistors in power supply, I found the culprit on second

Re: BNC that does not have the bayonet lugs
Condor mobile 2-way VHF/UHF radios had those "no lock" connectors in panel mount versions. Used in car mounts, the radio was on slide rails allowing easy removal/installation. In the Netherlands

Re: BNC that does not have the bayonet lugs
Hi john Yes that is possibly ok for the sockets as some BNC connecters do have a grove by the lugs but it is getting the mating connecters to go on the cable that is the problem Regards Paul Sent: 21
