content: It seems LeCroy has replaced the venerable WaveJet 300A (which was made by Iwatsu) with a new entry level scope with touch screen calledWaveJet Touch 300T:http://teledynelecroy.com/oscilloscope/oscilloscopemodel.aspx?modelid=8684&capid=102&mid=504The specs say 4 Channels only in 350MHz and 500MHz, 1GSa/s in 4Ch mode and 2GSa/s in 1-2 Ch mode, 2.5Mpts per Ch or 5Mpts in 1-2 Ch mode, triggering for I2C/SPI/UART.Like previous WaveJets this seems to be another Iwatsu scope, although this time it seems it's just a rebadge (the Iwatsu scope in question is the DS-5600 Series).Mouser lists the 350MHz model at $4514 and the 500MHz model at $5374 which seems rather expensive for such a scope with these specs.

For example, the Agilent DSO-X2000 is an entry level scope but certainly not a low cost scope. On the other side, scopes like the Siglent SDS1000 or Rigol DS1000(z) are both, entry level and low cost.A midrange scope would be something like the WaveSurfer 3000 which doesn't offer higher bandwidth but much more advanced functionality.

content: What is interesting is that Lecroy doesn't seem to rebadge Siglent exclusively.

content: It looks like an evolution of the WaveJet 300A which is perhaps not a bad thing. The inclusion of digital decoding and better triggering options are good.I've been generally very pleased with my WaveJet 300 which seems to be very well built.The couple of negatives I have are1.) In the very useful history mode there is no way (that I can find) of saving the whole history (segmented memory) in one go - it's immensely tedious to save each frame separately by manually turning the knob.2.) The wave-forms-per-second are rather low compared to Agilent and recent Rigol scopes but as I've not really done much glitch chasing this hasn't mattered to me.And of course as I only have the 300 not the 300A I can't control it remotely without purchasing a very expensive LAN card.The prices are pretty steep, but then so were the WaveJet 300A prices at official list (I got mine at around 65% off as it had been sitting unsold for six years).

content: Quote from: jpb on September 19, 2014, 03:38:27 pmI agree that the Iwatsu's are well built, my Iwatsu-built WaveRunners were certainly built like tanks as was my old WaveSurfer 400 (something I unfortunately can't say for my WaveRunner Xi which was made by another OEM in Malaysia and which is is of merely average build quality at best).QuoteI wouldn't worry too much about not having the 'A' variant as LAN was the same expensive option on the 300A. It's only became standard equipment with the new 300T.QuoteYes, but don't forget that in 2005 the WaveJet was pretty competitive in terms of performance and price (the flood of low cost scopes which brought pressure on the standard entry level market came much later). Unfortunately for LeCroy times have changed a lot since then.

content: Quote from: Wuerstchenhund on September 19, 2014, 04:15:35 pmThat is true, but the 300A allows control using its rear USB port whilst the 300 doesn't (it has a rear USB port with a sticker over it but it doesn't work for control purposes).
