Key specifications
- Differential inputs
- 12, 14, 16 bit resolution, 0.3 % DC accuracy
- Up to 50 MSa/s sampling, 50 MHz bandwidth
- 128 kpoints memory per channel
The WiFiScope WS4 DIFF is a 4 channel differential USB oscilloscope with a maximum sampling speed of 50MSa/s and 128 kpoints memory per channel. The differential input channels enable safely measuring, without risk of creating a short circuit through the oscilloscope. The WiFiScope WS4 DIFF is delivered with a complete measurement software package that offers all you need for your measurement applications.
Rugged industrial design
The WiFiScope WS4 DIFF features a rugged design. Its enclosure is fitted with rubber protectors at the front and the rear. These protect the WiFiScope WS4 DIFF against damage by mechanical shocks. The rubber helps absorbing shocks and protects the connectors at the front and the rear of the WiFiScope WS4 DIFF, these fall within the protected zone.
Additionally, the rubber prevents your WiFiScope WS4 DIFF from sliding. The rubber protectors have special notches that simplify stacking instruments. Holes are included that allow to connect a strap to hang the instrument near the test subject.
Differential inputs
The WiFiScope WS4 DIFF features four isolated differential input channels. This makes it the ideal instrument to perform measurements in high voltage circuits, amplifiers, switch mode power supplies, power inverters etc. No more risk of creating short circuits through your oscilloscope!
ast continuous streaming
Besides measuring in block mode, the WiFiScope WS4 DIFF is also capable of performing continuous streaming measurements. This will create a continuous uninterrupted data stream to the computer. The data can then be displayed on the screen and/or saved to disk.
