• Hello All
  
  I am looking for a decent handheld oscilloscope, and just wanting to know if anyone has any input of good/bad otherwise.
  
  Mainly using it for bench testing, however also for in the car and various things out and about. I know for equivilent money I could get a nice bench scope, however would prefer the portability.
  
  I came across the SIGLENT SHS810, and the SIGLENT SHS1102, along with the Hantek DSO1102B and Hantek DSO1202B. There are a few others too.
  
  I think I am mainly interested in the SHS810.
  Anyone know much about them? Good/Bad etc?
  
  I found this youtube review, however its in Russian, but it seems to give a fairly good overview on what the unit looks like and displays like: ?? ?? ?? SIGLENT ?? SHS800
  
  Any input would be appreciated.
  
  Thanks

• I also just found Sigilent SHS815 and the Sigilent SHS820, but it seems the SHS820 has less memory depth.

• mikeselectricstuff has a review of the Owon HDS3102M-N here:
  
  
  
  There's a teardown too:

• Thanks,
  Watching the vids now.
  
  Just realised the SIGLENT scopes are quite bad for sample rate with dual channel... hmm.
  
  Looking again and I see the Hantek DSO has a BV range which has 1M memory compared to the Kb the B range has. That puts it back in the spotlight for me a bit.
  
  Hantek also has a higher screen resolution over the SIGLENT.
  
  Will take a look at this Owon one in more detail now.

• Decided to go with a Hantek DSO1152S+LAN option, which is a 150Mhz handheld, 1M Memory, 1GS/s etc, Isolated inputs to GND and between channels.
  
  Will see how it goes when it arrives.

  Can you explain this your changed thruth....
  
  
  As far as I know 60, 100 and 150MHz models have
  For normal memory, realtime samplerates
  max 1GSa/s for 1 channel with 40k memory
  max 500MSa/s for 2 channels with 20k + 20k memory
  
  For long memory
  max 500MSa/s  for single channel in use  2Mpoints memory  (example Hantek 1M if even it is true)
  max 500MSa/s  for both channels simultaneously   and 1M + 1M memory (example hantek 500k+500k)
  
  This smaller memory leads to slower samplerate with slower horizontal speeds.
  
  what is now "quite bad"?
