Re: Are HP 70900A and HP 70900B interchangeable ?
Ron, What error messages are you getting? Documentation will be at hp70000.com, with CLIPS at Artek. Answer to your question will depend on your peripherals and 70900 firmware version.?? More

Re: Are HP 70900A and HP 70900B interchangeable ?
I have several 70000 spectrum analyzer systems. As far as I can tell, the 70900A and B are interchangeable. Mike <ronald.schiltmans@...> wrote:

Are HP 70900A and HP 70900B interchangeable ?
I have a defective 70900B local oscilator plug-in module. Cannot find proper documentation to start repair. To get my 70000 SA working again, can I swop the 70900B out for an older gen 70900A ? Any

Re: Frequency References
Add to this a fourth metric; phase noise. You won't be doing yourself any favor if the frequency reference you use in your shop is noisy.? Of course, you'll need to have some equipment capable of

1806A manuals
Hi Guys, I am starting to look at the 180 oscilloscope series. I bought a 180A and a 181A mainframes, a 1825A time base and a 1806A differential vertical amp. I could order the 180A and 1825A manuals

Re: Frequency References
There are two or three parts to "optimal" in the lab frequency reference context. The first is that if all gear uses the same reference, then they all will agree within +/- one count of whatever units

Re: Frequency References
I have one of these inexpensive units running to send 10MHZ to all my devices. Since the GPSDO runs on 12v it can be used with portable gear. Takes about 3 mins to lock from cold.

Re: Frequency References
In my case, I don't bother with a common reference piped around all my test gear. I usually rely on the various OCXO references in my test gear. I do check and adjust them every year or two. However,

Re: Frequency References
I'm not a time nut, so take this with a bit of salt. You're dealing with two things here in measurement, stability and accuracy. Accuracy you can get easily enough by a GPS, or even Rubidium, and in

Frequency References
Guys, I've heard people say that having a totally accurate external frequency reference available and distributed to all the test devices on one's test bench which can accept it is an optimal

Hello Yves_Tardif, unfortunately my initial answer bounced from the email address you sent me your program. Thanks for your program. The 5350B is really a weird beast! I made some initial tests on

Re: 410B Heater Voltages
Hi Richard, Alas, I think you may have learned the wrong lesson. The proper lesson, IMHO, is don't connect the 410B's AC ground clips to anything but a locally grounded, chassis ground. It's been a

Re: 410B Heater Voltages
Well, you answered my question, namely how hot do the probes get. The EA35 draws slightly more power than the 2-01C but both are close to 2 Watts so probably probes with either will feel the same. I

Re: 410B Heater Voltages
P = I x E 6.3V x 0.3A = 1.9W The probe's body provides a bit of heat sinking, but the 2W has to go somewhere. Cradle your hand around a 2W resistor running full power, and get back to me ;-) Heat is
