FDS138 Mini Digital Oscilloscope 2.5Mhz Sampling rate 200Khz Bandwidth AUTO 80Khz PWM for Electronic Repair Tool
Feature:
1. Use high quty material, durable
2.2.5MHz sample rate, actual bandwidth 200KHz, analog bandwidth 0KHz (sine wave)
3. With a complete trigger function (single, normal, automatic), it can be used freely whether it is a periodic analog signal or a non-periodic digital signal
4. The highest voltage signal of ±400V can be measured
5. Equipped with high-efficiency one-button AUTO, it can display the measured waveform without complicated adjustments
6. With a key to save the waveform function
:
Sampling rate: 2.5MHz
Analog bandwidth: 0KHz (sine wave)
Actual bandwidth: 200KHz
Measuring voltage: X1/±40V X10/±400V
Input Impedance: 1MΩ
Storage depth: 1Kb
display: 12 kinds
PWM output: frequency 1k~80KHz, duty cycle 0~100%, output voltage 3.3V
Function waveform: 17 kinds of waveforms
Output: frequency 1~1KHz voltage range Vpp 0~3.3V (not adjustable)
Display: 2. 4 inch TFT, 320*240 resolution
Charging voltage: 5V
Battery capacity: 600mA/h 3.7V
Host computer: currently not supported
Firmware upgrade: support
Dimensions: mm wide and 100mm long (excluding BNC head)
Precautions:
1. When measuring a voltage exceeding 40V, be sure to switch the probe position to X10
2. When measuring high voltage (more than 36V AC voltage), do not touch the metal part of the instrument, especially the position of the BNC interface
3. The charging voltage should not exceed 6.8V, so as not to out the charging chip
4. When not upgrading the firmware, try to move the toggle switch in the lower left corner to Nomal
Partial description:
1.2uS, 5uS cannot be used to measure waveforms other than sine waves.
2. Saving the waveform can only save the currently displayed part.
3. Some measured signals cannot be captured correctly by AUTO and need to be adjusted manually.
4. Firmware upgrade: To upgrade the display part, pre OK to turn it on, to upgrade the bottom part, pre SAVE to turn it on.
