This 0 ohm of transmitter output impedance hit me in 7am in the middle of coffee.. Its true, looks like 0 ohm on the system with output ALC, BUT only for signals with frequencies much lower than BW of

When you get into the land of video, circulators perform a slightly different task that makes operation even possible. Imagine what happens to a video, or high speed data signal when the transmitter

On the earliest 8753A, B, using the test set with the mechanical switches, this was common if you calibrated full 2 port. The signal has to change direction, and feed port 2 while measuring port 1,

Hello, I have the same configuration and encounter the same problem. The 8350 works well with the 8757A and I’ve tried both GPIB ports on the 8757A. Plotting the screen of my 8563E works

Are there not online resources in that area of Canada for plot maps and information related to the parcel?? That would have the info if not online, at the whatever is equivalent assessors office or

They do each have their place. I wouldn’t put up any equipment above 432 that didn’t have a circulator in the Tx output. Sure there is some loss but the advantage of the Tx seeing 50 ohms with the

While it’s not Agilent have you tried running, and I’ll get this wrong, NI Max or something like that from the National Instruments Suite. If I remember right this stuff is free on their site. At

A lot to us but maybe not to whoever spent it?

Whatever it is, somebody spent a _lot_ of money on it.

Are there vents?? Grow ops will need a good flow of air.? Are there HVAC units?? Cryptocurrency mining ops will need lots of cooling. Absent those it is either research or just selling power to the

Honestly it sounds, in local slang, like a "grow op."

Hi Marco, I have an 8757(C) with an 8350 sweeper but I use a Prologix Ethernet GPIB adaptor with it. That works in the way Vladen says except I have to do a power re-set of the Prologix adaptor and

Thank you so much Vladan. With the sweeper turned on, there was a leap forward! 8757A does not complain the lack of a plotter any more. I followed the above written istruction and eventually I saw the

If the System Interface Bus is OK, here are the instructions: 8757A settings: - Connect GPIB to the System Interface Bus - Set the plotter address to 5 in the 8757A “Local” menu 7470.exe settings:

Hi John, I have a junker here that has the same problem.? I took it apart and the buttons are not the carbon type.? It looks like and old style membrane keyboard with a conductive layer over the

Thanks for the ideas which can come in handy The measurement pictures I included earlier I sent to my chief engineer, I wasn't told what he would do with them but chances are he will send them to the

Hi all, I am looking for a 778D dual directional coupler. I've found one that claims "tested" on ebay, but it's a seller that doesn't offer paypal anymore and they don't actually say the result of the

Hi Tom.... That is because there is a leakage resistance across the switch contacts. That is what I was mentioning before about contaminants. If the resistance is not near infinity, the trigger

I have buyed a extension for my 54601A, the 54657A ( fft, storage, HPIB etc), and it comes with this message: The release of the scope must be 1.8 or later to use the extension. I have 1.7 so the
