Hey Freaks!

 

Does anyone here have an RF generator that has a range of 40Mhz to 2Ghz?  I am doing some work on a piece of kit that is used in Radio/TV transmission and I need a test source.

 

The range I am testing is -50 to 0dBM in the above frequency range.

 

IF anyone has one they would be willing to loan/rent/sell me send me a PM.

 

Thanks all.

This prob won't help immediately...I got one of these SMHU generators for a few hundred bucks in perfect shape....nice rig, but gotta get keep your eyes open for a low price

 

https://www.ebay.com/itm/Rohde-Schwarz-SMHU-Signal-Generator-100Khz-4320Mhz-835-8011-52-IEEE488/192403235888?hash=item2ccc206430:g:FGAAAOSwdjdaOYtI

 

It's a real boat anchor!

 

USA CARE with DDS boards---some may only have crude level adjustments, with no real attenuator (to save a few bucks)...so you just get whatever the chip outputs

 

This might do in a pinch:

I am looking a the EBAy route as well.  In fact I could use one of those crappy little DDS boards, but I would prefer to use the real deal.  Only thing is that this is most likely a one time thing so buying a couple hundred $$ generator is kinda foolish.  Hence why I am looking here to see if anyone has one they would rent me/sell me.

 

If I could get an output level spec from some of the crappy boards I would consider it.  I do not need Spot On accuracy...if it's off a little thats ok.

Wow that last one is tempting....June delivery though.

Sure can, and I have gone there many times.

 

I am simply asking here as we have a rather diverse community with backgrounds that are not only microcontrollers.  Maybe someone has what I am looking for, and may want to part with it.

No idea if these are any use.

Hi Jim,

I thought so too.  I think it was their advertising slogan long ago.  It is true, however, and should be because Flukes are expensive. smiley  I think people have become so literal these days that such tongue in cheek advertising wouldn't work any more.  It was mainly the knowledgeable users like you who got it.

 

Did you find an RF generator at a price you liked?

I have a nice list of them.

 

Before I go and purchase one, I need to have a long conversation with the punter as to the long term scope of the project.  As this purchase is application specific, if the end user is a one and done it is not in my best interest to invest in anything of quality.  some of the dinky board from we all know where might do just fine.

Well the search is over....

 

I found an HP E4400B off Ebay for $279.00 plus shipping.  It has an error in its HET VCO that I hope will not be a big issue but I have a 30 day warranty so we shall see.  I really just need it to generate the frequency and be able to set an output level.  if it drifts a little thats fine.

Nice, I like that old HP stuff. Someday I need to see if I can get an AVR to tickle a GPIB port. I will part with a lot of things, but I am keeping my bench equipment.

Despite that purchase; you'd still have to answer no.

 

E4400B 250kHz - 1.0GHz

I did say 2.0Ghz but i wont hit 1Ghz and 2Ghz are more common based on what i saw on ebay. Hence my original spec.

SDR transmitters can cover a large range.

 

https://www.rtl-sdr.com/tag/sign...

 

And can do so much more: TDR, antenna analysis, spectrum analyzer, sniffer.  But definitely not plug-and-play.

 

For example LimeSDR covers 100kHz to 3.8GHz with just about any modulation.

I have one of these on loan from a customer:

 

 

I'm only using it to monitor, but it says it can be a generator, too.

 

 

There's many options & variant - including a "naked" version available as a plug-on for a Raspberry Pi:

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
  4. Difference between a crystal, and a crystal oscillatorhttps://www.avrfreaks.net/comment...
