Yes it would be, I am not to sure how to do so. I would need to re-calibrate data ?

This would be the perfect time to upgrade the power capability if you desire to do so....

Dear Jon, ??? If you need that part, let me know. We have many here. Rick

Thanks everyone, After further investigation, it appears to be the 4db attenuator on the A4 Assembly. It looks like some signal was passing through (extremely low), only enough to read frequency etc.

The input resistance on the RF I/O? should be? very very? close to 50 ohms .? Usually? well within 5% and my upper limit is 10% ...should be? easily within 45 to 55 ohms ( make sure you factor

Thanks for the suggestions, I will check it out later today and let you know what I find. Just for reference, this is a 10watt version.

I recommend you measure the resistance from center conductor to shield of the R FIO connector. You should measure around 50 to 60 alms. Could be that high power and put a tenuator is open? Rick

Shortly after I got mine (about 15 years ago) - I discovered the same symptoms. I would first look at the attenuator on the A4 Assembly. My original one had the solder tab burned in 2. I guess enough

Hello, I am experiencing an issue when a device is connected in to the RF input. RF ANALYSER? screen RF POWER - The test set always displays a reading under 0.1 watts. even though a signal in is 5

Hi Rick, I'm late to this, but to answer your question, the Gonbes GBS-8200 or 8220 converters are a low cost option if you don't mind making a sync separator circuit and putting it in a box. The

Any chance you could copy/paste that list of components you ended up using here? Thanks for the info. Rik WA4BAN

Thanks will try that first!

That is how my E8285A was acting just before it got to the point that nothing at all happened when I pushed the power switch. Replacing all of the electrolytic capacitors and one tantalum capacitor on

Right, ? I would check the 47uF on the "daughter " board first. See attached picture. Rick

I reprogrammed the original factory firmware (rev 6.11) eproms with 14.14. They are all 150us parts. No difference. Also checked for bent pins at the CPU , signal and memory? board connectors. None

Appears to be a switching power supply, with a regulator board mounted above it. It seems the switching power supply is not starting up. Not even the fan runs. _____________ Rik Rasmussen

Hi Rik, I guess the problem will be on the rear most power supply board. Not sure what it is. Rick

My 8935 was working fine. Passes all tests. It was powered up on my bench and suddenly shut down. It will not power up. The GFI is not tripped. If I turn on the power switch the unlock led blinks and

I posed a while back about the 8924C my friend owned who died unexpectedly and I inherited. I fixed the PS but he had several screws and the PS cover missing, handles, trim, etc... I contacted

My 8594E failed the CAL AMP at the 1 kHz step. I aligned using the instructions in the manual, including making up a set of of shorting plugs. I also referred to a great posting at EEVblog Forum with
