content: The most bang for buck signal and arbitrary waveform generator at the moment is the Siglent SDG2042X.It can be easily "upgraded" to 120 MHz. Dave Jones did a review about it on YouTube.

content: It is more than 100% more expensive than the UTG2025 from kjell.com. And I do not need 1.2GSa/s sampling rate and 16-bit vertical resolution.Do you know who sells the Siglent SDG2042X in Norway?Johan-Fredrik

content: Never buy from Kjell.com. Too expensive for what you get.When it comes up to Rigol stuff, you can go for Instrumentcenter Sweden.They don't carry Siglent stuff though.If you don't want to go for the Siglent SDG2042X, then a cheaper alternative is the Siglent SDG1025.Batronix in Germany carries Siglent stuff.Can't advice on a Norwegian supplier though.

content: I do my best not to buy anything from EU member countrys. The Norwegian authorised Siglent distributor is registred as a one year old programing outfit with only two employees and no website! So you are forced to email for a quote and that is something i refuse to do.Johan-Fredrik

content: Quote from: LA7SJA on July 24, 2016, 10:21:27 pmDo consider that being a small company with low overheads they may be able to offer just as competitive pricing as those that might have a high sales throughput.The US Siglent pricing is used as the worldwide benchmark, convert to local currency plus taxes if any.At present I don't offer website pricing because in NZ we have a somewhat volatile $ so in an effort to offer the best current pricing I only price on request. There's not a lot of difference from week to week, but month to month there can be but for the savvy customer indication of cost is always on the Siglent US site. But hey you've got indicative pricing on the Siglent Hamburg site too.http://www.siglenteu.com/index.aspx

content: www.siglent.nohttp://m.finn.no/bap/forsale/ad.html?finnkode=76776147His price looks about what you would pay to get it directly from China considering taxes and customs.Rigol you can get from venotek.no most likely cheaper than Kjell

Venotek do not have prices on the web so I refuse to deal with them (or anyone without prices on their webpage)! Anyway, I am still interested in any review, unboxing, teardown or test of the Uni-T unit.Johan-Fredrik

content: Honestly I am very surprised why neither Adroit.no and Siglent.no have an active website.Okey, the oil prices are gone down in Norway, but does that mean neither of them can afford webserver hosting?Or is it true that Norwegians have become lazy because of their wealth.Power to the Swedes! =)

content: Quote from: xzswq21 on November 06, 2017, 06:49:19 amIf you look closely at SDG1032X (30 MHz) both sine and squarewave go to max frequency.The Ramp/Sawtooth waveforms symmetry can be adjusted to have a variable rise or fall time.
