Also, common FGs are capable of putting out quite a bit of power, so it's good to be wary of the actual level - accidentally setting the FG's output improperly could put the SA at risk. A DC block,

Mark You are correct, I found the 9060 ohm SMD resistor had changed value Replaced, now good, had to cobble a couple resistors together, but they fit in the case. Thanks Wally KC9INK

In all function generators I know about, both square waves and triangle waves have a default DC Offset of 0 Volts. (They go above and below 0V equally.) Adding in a DC offset is usually a separate

Hi, I have already made several programs for image capture on HP devices, maybe I may help you, but I can't find the 8934C, is it the 8924C? De : [email protected]

Do you have a source for it being MFM (Double Density)? Everything I can find, and the age of the instrument, indicates FM (Single Density). Indeed, it's FM, single density => my fault, still under

This is totally doable. If you're worried about DC, which is good practice, a DC block will take care of it for you. These are cheap and widely available. E.g.

Has anyone used GPIB to capture screens on this unit? If so, get me started in the right direction.

Glen, Thanks for the ‘ID’. I can certainly read, archive, post and/or distribute the contents of a 27256. I looked for a manual for the unit but I did not think to look at hpmuseum. Happy to help

Hello friends, I'm repairing my hp 3585A, which shows "LOCAL OSC. UNLOCKED" on the screen all the time and a flat horizontal plot at the bottom of the graticule. I'm following the service manual and

I received this email that I thought might interest other RF junkies: Demo: PNA-X Spurious Test Dr. Joel Dunsmore will walk through a 20-minute demo showing optimized spurious testing with the

Great replies, thanks

Hi Wally, There is a resistor inside the probe's compensation box that informs the scope of the probe's multiplication factor.? Check the resistance from the 1160A's AutoProbe pin to ground and

As a way to protect Analysers when used by less experienced I use an external blocking cap and a DC return as I don’t use a spectrum analyser below 1 Mhz The DC return part number HP 0960-0092 also

Well, if you think about it, a square wave is a perfectly valid signal to feed into a spectrum analyzer. All waveforms, regardless of shape, can be decomposed into sums of pure sine waves of different

Hello, Just a few notes about the 4145a format. There is no magic about it and it's a standard MFM (not GCR format fortunately). Since 4145a as well as 4145b both use Fujitsu controller MB8866, which

I would think, like with audio amplifiers, it would show the actual frequency response and distortion as well as group delay. I remember close to 40 years ago I was asked by a three letter agency to

Although I have never tried this before and not sure if I would recommend anyone to do do this, to take a function generator and apply a triangle wave or even a square wave at about -20 to -30dBm into
