Product Information

It's a nicer device if you plan to use it as a bench device since you have the native software and large screen. Above, my cmd file also spins off an inverted colour version which is better suited to printing and some online display. This calibration kit can be used with any SMA connector device, such as the MiniVNA Tiny and PRO2 or NanoVNA and any VNA. The benefits are larger SRAM 40KB from 16KB, larger flash 256KB from 128KB, faster CPU clock 72MHz from 48MHz, and floating point accelerator.

I'm happy to have my hands on the 4" NanoVNA-H4 and can deal with a few warts knowing hugen will address them in a timely matter. To build the largest and most complete Amateur Radio community site on the Internet - a "portal" that hams think of as the first place to go for information, to exchange ideas, and be part of what’s happening with ham radio on the Internet. PC Control] Using PC software NanoVNASaver, NanoVNA-H4 antenna analyzer can connect to a NanoVNA and extracts the data for display on a computer, and for saving to Touchstone files.This Antenna Analyzer is provides outstanding vector network measurement capabilities and perfect for evaluating antenna resonance and SWR. I've started looking into NanoVNA so I can understand a bit more about antenna performance and design. Thanks for confirming the issue and also for confirming that updating to the latest firmware version doesn't correct it.

If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag.

Read the SWR measurement: The SWR chart is displayed in the software, with the frequency range on the horizontal axis and the SWR values on the vertical axis. The magenta trace is after removing the frequency offset against 10MHz and after correcting also the frequency drift - as mentioned, the 53132A was only recently switched on and it's reasonable to assume that it will drift for a while before settling. Some of these create more questions than they answer and require more analysis so don't just accept them as absolute truth. A valid product review is one where you have personal experience or knowledge of the product that you would like to share with others. Setting start and stop frequencies, instead of center frequency and span, as you already found out works fine above 1 GHz.
