content: The dbm error on the SDG 1020 has been fixed in firmware release 1.01.01.27The firmware can be downloaded from the Siglent website athttp://www.siglent.com/en/product/detail3.aspx?id=100000001526838&nodecode=119008003you will need to register an email address to get the download.Two notes -1/ When you do the self calibration (required after a firmware upgrade) ensure you switch off the outputs and disconnect any cables - as any loading on the outputs can result in erratic calibration levels.2/ If dbm is your preferred output, I'd recommend setting db as the output mode and 50ohms output impedance before doing a cal.The SDG1020 is a nice generator, which Id happily recommend, however updating the firmware is a must as the early version were quite buggy.Hazzer

content: Hello Friends:First of all sorry for my poor English.I am dedicated to the repair and calibration of test equipment, I also do designs for verification and calibration equipment in laboratories and in the field.I bought a SDG Siglent 1020, I read everything about the this great forum, I checked even the most hidden possibilities.The truth is that initially the most surprising thing is the price, but you can not compare with WaveStation as the Siglent is not all he wants to be.It came with firmware P27, with the problems in the forum have commented, as I have seen that they are all truly uncomfortable I decided to install the version P31R1, thinking that all problems would disappear, has not been so, I've noticed that still has many bugs, including and most important are the offset, non-linearity, and that changes the waveform in some cases is around 100mv (eg with output 1 Vp-p), but not at any time precise output values??, this occurs in all output options, increasing the more the output is low, not being suitable at any time as test and calibration equipment.Another of the many problems I've found: When the output is used in dBm OUTPUT mode if you press RIGHT ARROW below and switch to mV pp / pp V so far lost in dBm, I think there would have to occur, consider a major failure.Another very important issue is that after updating the firmware P31R1 and you can not go back, I think that this question makes it clear that is not a serious or suitable laboratory equipment, losing interest in their lack of precision and especially for its lack flexibility.Greetings.
