Moderated Re: Recommendation for an "up to 1GHz" generator + sweeper
John, This is a brilliant idea. I assume this would also allow good control over the sweep vs. readings. A whole world of possibilities. Lothar, Strictly for sweeping IF filters, the NanoVNA is

Thats what i am doing to test PAs , use a CW generator and power meter and control it using labview, there are however 2 caveats to this approach . First of its slow especially if you cover wideband

Radu, Lothar's point regarding the frequency stepping as opposed to frequency sweep is a good one for the hobbyist to bear in mind.? For bench measurements of components and subsystems you're usually

Dear All, Re RP protection, I think DC protection is a different matter. For example many SAs have an input power limit of +20 dBm and 0 V DC. You have to check spec. carefully. Re DC protection, it

Re: the possible need for I-Q modulation, if the required generator does not have it internal it can be added as an external modulator to the output signal. External I-Q modulators are not cheap

8642 is in that boat for example. But one could craft a bit of,say, Python and drive the sig gen and a suitable meter and you have a poor man's scalar filter measurement setup. Takes a bit longer

Some of the GPIB controlled synthesized generators could be "swept" in GPIB code...probably not as quickly or smoothly, but...then you can code the post processing to be whatever you want, and insert

Hello Gerald and others interested, I have a FS2772R-smt TINYig from Teledyne (4-8 GHz) that I tested on the bench and it works quite good actually. Very easy to operate and it certainly works down to

What is Option G20 on an HP 8648D Signal Generator?
I have an HP 8648D signal generator that says "Option G20" on the rear label, By pushing various buttons, I've found that this option seems to include at least the modulation generator (option 1E2)

Just double checking: you did connect the DB25 cable from the 8516 to the source ? Also what source are you using?

With the 6 foot cable my system seems to be about 40% working. From 20-40GHz S12 and S22 sometimes fully work. S11 and S21 only up to ~30ghz works, then the NO IF FOUND errors comes up. Changing the
