• Model: Handheld Oscilloscope DSO2512G - Zeeweii Instrument Co., Ltd.;

• Shape
• Very small Portable or Pocket-Set (Handheld) < 8 inch.

• Dimensions (WHD)
• 82 x 137 x 38 mm / 3.2 x 5.4 x 1.5 inch

• Notes

• The ZEEWEII DSO2512G Handheld Oscilloscope features two vertical channels with a maximum sensitivity of 10 mV/div and a minimum of 10 V/div, a time base of 5 ns to 10 s, and an alleged 120 MHz bandwidth with a 500 Msps sampling rate.

  It includes an Arbitrary Waveform Generator with a fixed output voltage of 2.5 Vpp with a maximum frequency of 10 MHz sinusoidal, and up to 2 MHz on the others shapes like square wave or triangular.

  The 2.8 inch screen has a resolution of 320x240 pixels.

   

  Brief technical details

  The signal sampling and analysis uses a single MXT2088 ADC able to run two channels at 100 Msps each (125 Msps in overdrive mode) coupled to a AG1KLP48 FPGA. 

  Alleged 120 MHz bandwidth requires to disable the scope vertical channel 2, allowing the ADC to combine the two channels to have a total of 250 Msps. 

  However the manufacturer does not specify in what conditions they have measured the alleged 120 MHz bandwidth, like what was the source signal exact amplitude, and what was the 120 MHz signal attenuation when acquired by the scope.
