Test Equipment / Re: Rigol DSA 815 Spectrum Analyzer

Ok Buddy...   I do have a Bird Meter but it does not have the sample port installed.  I'll be looking on You Tube to see if I can find something.  I do have two ( "T" Style ) Bird RF Variable RF Samplers Series 4273. One has a range of 1.3 - 35mhz and is capable of 40 to 70 db of attenuation below the main power level. The range of the other is 20mhz - 1ghz. and is capable of 35 to 80db of attenuation from the main power level.... I believe these would do the trick... just uncertain as how to set them up for reliability.  Guess that's enough for now off to do some more searching..

Test Equipment / Rigol DSA 815 Spectrum Analyzer

Looking for some suggestions for my newly acquired toy...... 1) I know a DC block is a good thing to have going into the input of the analyzer,  is there a specific type I should purchase.  2) I would like to use this to monitor RF from a transceiver or transmitter to check performance related issues.... I believe I should get a 100 watt 40db attenuator minimum to protect the front end of the analyzer.... but perhaps I could be over thinking this...  I do have a couple of Bird RF samplers which would probably suffice but am unsure as how to set them up.

I'm a newbie to this type of toy....  I did look at some local signals and was pretty impressed at what this machine can do.... too bad there isn't a Spectrum Analyzer for "dummies" video fo this analyzer.   Any suggestions would be elcome.  Thanks in advance.

Test Equipment / RCA Senior Voltohmyst

Well I'm restoring an RCA Senior Voltohmyst model WV-98C.... I'm in need or need to build the dc/ac ohms probe..  The probe that came with the meter was completely wrecked and had to remove the housing from the insides of the probe and might be able to place the guts of the probe into a different housing or maybe someone has built a few probes for vtvm's and can suggest what to use so I can build one.  Any suggestions are welcome... the restore is coming along quite well... Thanks in advance...
