5 channel input, synchronous display. Automatic measurement of amplitude, 4 measurement modes optionalInput capture (trigger) functionAny channel can be set as a capture (trigger) sourceCan set rising or falling edge capture (trigger) signal. Capture (trigger) signal level adjustable. Data can be saved to the computer, automatically transferred to the saved data when the software is started. Data can be backed up, and later at any time to view the backup data waveform. Can display any two channels of differential signalLock signal to expand and compress waveforms up to 93 hoursSuitable for monitoring the operation of electrical equipment for a long time and archivingSuitable for collecting and archiving data such as temperature, humidity and light for a long timeWireless Communication: Wi-Fi 2.4GInterface type: -USB 2.0Signal input interface type: BNC interface, connected with the oscilloscope probe lineMaximum sampling rate: 150 kHzOperating voltage: 5 V -USB interface power supplyConsumption current: Less than 170 mAMeasurable frequency range: 0Hz-----50 kHzAmplitude adjustment range: 10 mV/-----1 V/Input impedance: 1 Mohm (Less than0.5V/) ; 330 ( 0.5V/)Maximum measurement voltage: 8 V, 80 V for probe X10Amplitude error: 2.5%Time domain range: 100 uS/-----10800 S/Data recording and storage depth: 8388608 * 5Maximum record and save data time: 93 hoursConnection :Fosc53B oscilloscope has three connection methods, the software can automatically select the connection mode:1. Use USB cable to connect the oscilloscope to the computer. When the computer does not have Wi-Fi and cannot connect to , this connection mode is adopted. This connection requires aUSB driver to be installed on the computer.Colour:As ShownMaterial:plasticPackage Contents:1 x Fosc-53B1 x USB data cable5 x BNC connectorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
