Re: FT818

Hi Ed

 

We have just had a thread about power measurement and protecting test equipment such as spectrum analysers

 

Any DC on a coax or on a RF signal has  a high possibility of causing a disaster resulting in £100’s if not £1000’s of damage

 

So please be advised that even the DC on a LNB cable can kill a HP noise meter and this is after a blocking capacitor?

The problem is the spikes from connecting / switching  on and polarisation switching voltage go through the blocking capacitor

There is advise from HP on how to minimise the risk

Is anyone using the FT818 as a microwave IF? Is there a simple mod to put volts on the RF output on transmit like the FT817?
