Gear selection: the output voltage of power amplifier is generally below 40V, and the maximum test of 40V in the 1x gear is enough (both probe and oscilloscope are set to the 1x gear). It should be noted that if the captured waveform is a single cycle waveform, that is, there is only one cycle in the two bound ary lines, then the output frequency of the signal generator is equal to the frequency set by the signal generator. All oscilloscopes in the world will change their cards when measuring 50Hz signals, not because the oscilloscope itself is stuck 13: Why is the peak value of VPP more than 600 V and not 220V or 310V when measuring the voltage waveform of the city power?

Even if it has bandwidth of 30MHz, it’s still a decent tool in my opinion for people who can’t afford anything better. There are Owon, Siglent and Rigol scopes that are only a little more expensive and much more accurate and user friendly. Dave’s video where he actually measures the device with an actual signal generator that he trusts is what should have been linked in the article. This is the frequency at which the measured value of the amplitude of a sine wave will be 3db lower than its actual value. I would never have imagined of a such disappointing purchase, I have an oscilloscope that is totally useless for measurements of low amplitude signals.Combined with memory compression technology, it ensures a seamless, flicker-free waveform refresh experience.

An example of this is the measurement cursors that aided by the direction keys allow us to easily move the cursors around the screen.
User-Friendly Operations: One-button auto and cursor measurement functions simplify complex readings. Dave at EEVBlog did probe the FNIRSI 1013D and verified that the ADCs were only clocked at 200MHZ – I suspect it’s the same for this model. I tried slope triggering, it helped only a tiny bit, there’s no way to keep the trace steady on the screen. Easy to Observe: Equipped with high-efficiency one-button AUTO, adaptive 25%, 50%, 75% trigger, can display the measured waveform without cumbersome adjustment; the display is equipped with a 7-inch 800*480 resolution high-definition LCD screen.

The captured signal can be saved to the system, and up to 1000 groups of captured signals can be saved. Another fantastic unit for this entry-level line is the Owon SDS1102 or the Owon SDS1104 ( see my review) for a 4-Channel oscilloscope, which despite having a slightly higher value, already has functions that do not exist in this one. FNIRSI-1013D provides a one-button auto-adjustment function, avoiding tedious manual adjustment, and the dual-channel display facilitates real-time waveform comparison. FNIRSI-1014D is a two in one oscilloscope and signal generator, the real-time sampling rate is 1GSa / s and with 100MHz* 2 analog bandwidth, with 7 inch TFT LCD display screen, the built-in high-voltage protection module can tolerate up to 400 V continuous voltage, without worrying about the oscilloscope burning accidentally caused by the probe not moving to 10x gear.

Gear selection: the battery voltage is generally below 40V, other DC voltage is uncertain, so it is necessary to adjust the gear according to the actual situation.
I love my tools and have quite a collection of somewhat expensive stuff although all I do is dabble in hobby projects …” Well said.
Great Deal
