Vector Magic Desktop Edition Serial Number has a suitable drag-and-drop user interface which allows you to load, change and save pictures very rapidly. Please tell me why did the instrument displayed what it displayed I had bad experience with RS high end devices in the past. I thought the low energy symbols remain (more or less) intact and the high energy symbols at the perimeter of the constellation diagram cant reach their nominal location so their distance from the origin is smaller then during non-compression. It looks like the I and Q components become larger then what they are during non compression. When the amplifier gets saturated the constellation points start to move OUTWARDS instead of INWARDS. When Shahriar reviewed the instrument he performed QAM demodulation measurements on a saturated amplifier (see attached picture). SVA1032X has QAM demodulation feature therefore I tend to put my vote on that one, but I have a serious concern. Obviously that will take longer though, and so there will be a trade-off in drift to get the benefit of reduced noise. ![]() ![]() However if you do the error correction on a PC then you can use averaged sweeps of the calibration standards and then apply the error correction to averaged sweeps of the devices. I am keen for Siglent to support OSL calibrations on Port 2 at some stage to make this a bit easier.Īnother point which was raised by member graybeard is that calibration standard sweeps cannot currently be averaged on the device. With that in mind, there is the option of using an external coupler between port 1 and 2, save the sweeps, and do the calibration on a PC. So turning on averaging, having a good warm up and a stable environment help.ĭoing the calibration and the measurements quickly also matters more in that region.įor HAM use, having the capability to do the measurement is generally more important than the convenience. So we see more noise, and the device becomes more sensitive to things like temperature changes. The error correction maths amplifies the directivity which is great, but it also amplifies all of bad stuff, like noise and drift, which is bad. Other VNAs dont have a built in calibration and on them you can easily see the basic performance of the coupler just by attaching a 50 ohm load.Īnd when you do a cal, the magic of the error correction maths makes it a perfect coupler again However, when the coupler is operating in this low frequency region where its directivity is poor, what is observed is the noise and also measurement drift increase.
