New firmware for Stick230. #stick230 #firmware
Dear friends! We have released a new firmware version for the Stick230 analyzer. This firmware adds two new features: - custom OSL calibration. - the ability to load / save measurement results into

Antscope2 v1.1.3, AA-600, WIN10 2004, TDR X-axis very inaccurate when zoomed in
Hello dear Alex and Group-Family :-) Can you please check urself and correct the units when zoomed in to the maximum in the TDR mode for the next software revision 1.1.4? I made some measurements with

Re: Antscope2 TDR Y axis units
Hello Kirk, At the moment, this function is not available in AntScope2. I passed your wish on to our developers. If there is a technical possibility, then this function will be implemented./ Best

Antscope2 TDR Y axis units
Is it possible for Antscope2 to display absolute Z on the Y axis in TDR mode? Currently it displays a value relative to Zo. I wish to display absolute Z in ohms. I understand that the absolute Z value

Re: AA-230 Zoom - measuring chokes
Hi Tony, You can in fact measure the impedance (R and X) of a ferrite cored common mode choke with the AA-230 Zoom. The AA-230 Zoom uses a 10 bit ADC, so that is a greater limitation on resolution

Re: AA-230 Zoom - measuring chokes
Roger, Thanks for the info. Since I don¡¯t need to do this often, decided to trust my construction technique and just follow the instructions to build the chokes. 73, N2TK, Tony Sent: Tuesday,

Tony, The RigExpert is a one-port VNA that measures the magnitude and phase of the complex reflection coefficient *¦£.* The relationship between *¦£* and the device-under-test (DUT) complex impedance

Re: AA-230 Zoom - measuring chokes
Tony, thanks! Tell me if I can be of service to you in the future. By the way, if you have a couple of minutes of free time and desire, please share your experience of using the analyzer here:

Re: AA-230 Zoom - measuring chokes
Alex, Thanks for the feedback and the article info. Looks like I will need to spring for a VNA if I want to measure the common mode choking impedance. I really like the AA-230. It was very helpful

Re: AA-230 Zoom - measuring chokes
Ok Tony, AA-230 Zoom is not entirely suitable for these purposes, since the analyzer measures the S11 parameter (reflection coefficient). For such measurements, a device measuring S21 parameter? is

Re: AA-230 Zoom - measuring chokes
Alex, Maybe I am using the wrong words. I wound a few coils on ferrite cores based on literature. What I would like to do is see if they measure similarly to the literature before I install them.

Re: AA-230 Zoom - measuring chokes
Dear Tony, Let me ask you a few questions: For what purpose do you need to measure the impedance of a choke? For example, when calculating and manufacturing various filters, we need to know the

Trying to measure the choking impedance of some chokes I wound. Using #8 to display all parameters. Frequency set to 1800 KHZ. I am getting strange readings. As an example, chokes wound with a pair of

Re: Rigexpert Antscope2 is working in my nanovna-h
Same here!? Just picked up a NanoVNA-H4 and after testing with it's own software, I opened Antscope2 and it connected and works perfectly! Woo Hoo!

Re: AA-30 calibration?
Hola Jorge, Yes, indeed, the AA-30/54/170 analyzers do not have an OSL calibration function. /Best Regards, Alex Antonov UR4MCB / // 08.10.2020 18:03, Jorge Diez - CX6VM §á§Ú§ê§Ö:

AA-30 calibration?
Hello I need to calibrate my AA-30 I found a video for the AA-230, that it has a calibration option on the main manu. But AA-30 don`t have it. So is not possible to do a calibration on the AA-30?
