Fnirsi DPOX180H and Hantek T3100 100MHz Oscilloscope Probe X100 Passive Probe
(1/1)
tpd:
Hi, I Fnirsi's manual have found that x100 or evem x1000 probe should be used for high-voltage measurements:
"The bandwidth of the 1X probe gear of the accessory probe is 5MHz, and the bandwidth of the 10X probe gear is 200MHz. When measuring a frequency higher than 5MHz, you need to switch the probe to the 10X gear, and the oscilloscope should also be set to the 10X gear. Otherwise the signal will be greatly attenuated, as is the case with all oscilloscopes. Because the probe line of the oscilloscope itself has a capacitance as high as 100~300pF, which is a large capacitance for high-frequency signals! The signal has been greatly attenuated when it reaches the input end of the oscilloscope through the probe, and the equivalent bandwidth is 5MHz. Therefore, in order to match the hundreds of pF of the probe line, the input end of the probe line is first attenuated by 10 times (the switch is at 10X), so that hundreds of pF capacitors are just used for impedance matching.
At this time, the bandwidth is 200MHz. Note that only probes with a bandwidth of 200MHz or above can be used."
Since Hantek's probe is for 100 MHz, can it be used with Fnirsi?
Thanks
