Owon MSO 7102T, I cannot afford it. 2 features logic analyzer and battery4hours

[Lawsen]

In the U.S.A., the Owon MSO 7120T is available at Motion Controls store web site for $879.00.  It is not for students like the Rigol 1052E in Davy Jones's table or his videos.  The Owon MSO 7120T is better than the low end Owon with 250 MSamples/s in 25 MHz and 60 MHz versions for around $300.00 with battery option for $55.00 run time is around 3 to 4 hours.  The Owon MSO 7120T Specification is:
Bandwidth 100 MHz
Sample rate in real time is 1 GSamples per s at one channel only.  When two channels are used, the sample rate is halved into 500 MSamples/s in channel A and 500 MSamples/s in channel B.  
The rise time is less tan <3.5 ns
The display is standard VGA with 8 cm diagonal.  

The logic analyzer timed with 16 channels with a slower sampling rate at 20 Samples/s to 400 MSamples/s and the square wave pulse bandwidth is 66 MHz with a memory of 4 Megabits/channel.  The set includes the 16 channels wires probe pod that snaps onto the front of the oscilloscope.  Do I need it?  No and it costs too much for a geology person.  I would like to work on seismographs, but the Rigol 1052SE is more than adequate and less than half the price.  I do like the Owon because it has a battery option.  I like battery powered instruments, do not know why and do not need it as oscilloscope is used mostly at my table.  

I wrote this because I do not want the thinking that Rigol is the only one with a 1 GSamples/s, but Rigol is the few that is best for the value.  The Rigol is the only one I can afford in my room.  

I would like to try the Hantek DSO 8060 graphics meter and arbitrary wave form.  What I would like on my table is:
second hand HP Agilent power supply
Rigol 1052E
my Stanford UC Riverside USB earthquake catcher seismograph.  I graduated from San Jose State.
HP-3468 E Bay found multimeter
Agilent U1253B in the orange case.  The Agilent U1253B changed colors from the U1253A version that Davy Jones reviewed last time.  
Philips PM2518 vintage multimeter made in Holland
Fluke 187, discontinued.  I used to have a Fluke 8060A, but it broke on me and I traded it in at Fluke.  
Fluke 12 with worn out button pad and I repaired it myself.  It is discontinued and no parts for it, but well made.  I can repair it myself.  
Radio Shack Micronta analog multimeter made in South Korea was my first.  I cannot afford a Triplett or Simpson 250 analog meters.  
Yes, I have Radio Shack many in one electronic project sets with the spring wire clips from childhood to adult hood.  The new Radio Shack kits are wireless with snap on component modules with their symbols sticked on it and the most expensive one has a feature to use the USB port in the PC as an oscilloscope to view wave forms of your project assembled.  
Small pencil soldering iron
I have a nice plastic Zeiss DR1040 stereo microscope, with Greenough optics mainly for geology and mineral viewing.  I have used it to check my soldering quality in my Sony stereo.  Sony refused to repair it and sent it back to me unrepaired.  Sony wanted to me to buy a new one that is not the same and not as nice looking as this one.  I used an NTE Electronics power amplifier and added a fuse holder to protect.  I was the stupid one that ruined my Sony stereo by connecting a large HP all in one printer, fax scanner, and copy machine power supply to the Sony and blasted the amplifier to smittereens.  I regretted this for life, because my Sony stereo works, but sounds like an ECG Philips NTE amplifier, not an original Sony amplifier.  Sony Amplifiers sound flat with low treble and more bass.  Philips ECG NTE amplifier chips sounds more lively with higher treble and less bass.  The amplifier replacement makes the Sony sounds different, more like a Philips stereo.   Replacements rarely allow the repair to be like original, unless the exact replacement part is available.  I do not have a signal generator.  I might try to build one myself from the Delton Horn books.  I would like to work and save for the Hantek DSO-8060 with the wave form generator integrated.

What were my most difficult project?
I replaced the power amplifier in my white color case Sony Sports beach stereo and my mother's exercise thread mill machine's motor controller that was burned by the 12 kV surge when a car crashed into a electricity cable pole.  

Seeking a job is tough as Stockton, California is 3RD largest forclosure of houses in the U.S.A. It is tough here.  I hope, I do not have to inquiry as far as Namibian open pit fluorspar mines for work.

This model has better specs.  But some thoughts.

A battery powered oscilloscope has to be specifically designed to be battery powered because the input leads will float relative to ground.  This may be safe to use as a logic analyzer but it carries a bigger risk of bricking your scope when used to measure analog signals.

4 hour battery life is fairly impractical as is, when the battery ages in say 1 year, its life will be even shorter.

I just saw the manual, and it only has 6kpts memory depth.  This is far inferior to the Rigol; you can get a 100 MHz Rigol with logic analyzer for nearly the same money.  The specs of this model are so similar to Rigol  wonder if this is clone of the 1000 series.

Note that some battery powered scopes (especially those that can be switched between battery and mains operated) still have to be grounded. They usually have an earth pin or screw somewhere for that purpose.
