Carlos, I suggest you always search the archives for old posts on a subject. Often you will find the topic has been discussed before (often at great length). Here is one that will interest you. ...

The unit we had when I worked at a Bell System operating company, designed by Bell Labs and manufactured by Western Electric, had the rods firmly embedded in holes in the larger diameter longitudinal

Fun, right? As Dave mentioned, you will get a more accurate reading if the level lower, but it will be fundamentally similar. This is part of the clever design of the nanovna, analogous to the clever

I notice a measured level of -10 dBm. I believe Eric recommends for best performance and minimal aliasing to keep the input level at or below roughly -30 dBm. You might try the same sweep with a 20 dB

Ok Stan, you got me! See picture. The marker is on 400MHz. I am seeing signals both above and below the fundamental which is not even the strongest signal. The other signals go in 1/2 harmonic steps

QUOTE (Jim Lux): The trick is that the apparent values are affected by the gain of the the * Making the measurement with no bias gives little to no information. Note that all the datasheets of

Most don’t know this and its been heavily downplayed but the implications are specific. We watched two stellar masses merge. The gravity detection array vibrated from the merger several seconds

WARNING: MORE OFF TOPIC And only last week I read a paper that proposed that in the big picture of the universe which we are just on the verge of detecting, that as well obeys quantization rules much

Thank you, I will study what was suggested. -- Carlos Delfino Equipe Basic?o da Eletr?nica <https://basicaodaeletronica.com.br> Celular: (85) 985-205-490 (OI) - Aquiraz/CE

Neither strings. Seriously. If everything vibrates regardless of the distance, then its connected. The issue is the propagation time and what's in-between that may absorb or reflect some of the

I would think that you would do it by setting up a circuit with the transistor in an operating configuration (whether CE, CC, or CB) with biases, and DC blocks to/from the VNA and then measuring the

If a transistor were biased as in use, one could decouple the DC bias from the VNA and measure the junction capacitances. Just keep the RF drive extremely low as to not upset the bias point of the

WARNING: OFF TOPIC Take gravity. Einstein did an exquisite job of explaining the EFFECTS of gravity. That's all from the respect of the EFFECTS of gravity on propagation of EM waves (bending light,

Hello Michael, thank you for your attention. In this case, the question is particularly about using the VNA, using an LCR or a common capacitance meter I have no doubts. -- Carlos Delfino Equipe

First, in order to determine "parasitic capacitance" (which is generally determined by the sum total of the circuit components and their interaction within the circuit) you must determine the junction

Further to the SWR vs Resonance thread, I have started a new thread here. Have a look at https://youtu.be/-F7KYLO4Bkg?si=v6utQyiV5rKRwYPi There are some excellent comments posted as well. Should we

Some stations have more watts to contend with than others. SEE this photo taken of the SWR and Power meters at the VOA site in Greenville. NC. 73 Bill, K2TNO [email protected]> wrote:
