Hi Matt:
Is it possible to make a DC measurement (DMM Diode function) of the SRD forward
and reverse voltage?
Have Fun,

Just bought a
Zeta Labs X76 Multiplier 7600 MHz Output Model 5856-01
on ebay. Anybody have any info on these? What kind of drive should I give it?
Thanks,
Matt

Matt,
You'll be very lucky to find data for an old exotic beast like that. It looks

Thanks Rick. My main reason for buying this is to be able to better
measure the phase noise of my 100 MHz oscillator. I figured this
would give a truer measure than a brick since there is no PLL
involved. But then I thought there might be too much filtering going
on. If the filters are at
This is a complicated question. First of all, there is definitely
no crystal filter involved. However, the multiplier can have its
own phase noise due to either the amplifier or the SRD. There can
also be AM to PM conversion and vice versa. I have found the
technique of multiplying a source to
