New and improved handheld two-channel digital oscilloscopes

29-04-2022 | Saelig | Test & Measurement

Saelig Company, Inc. has released the new and improved Siglent SHS-X Handheld Two-channel Digital Oscilloscopes offered in 100MHz and 200MHz analog bandwidths and isolated or non-isolated versions, with 1GSa/s sample rate and 12Mpts memory depth. The SHS800X versions offer two non-isolated scope channels and one isolated multimeter channel. In comparison, the SHS1000X models feature-complete isolation: between the two oscilloscope channels, the power adapter, the multimeter channel, and the USB host/device port. The maximum analog voltage input for the isolated SHS1000X channels is CATIII 600 Vrms, CATII 1000 Vrms. For all models, the maximum input for the multimeter channel is CATIII 600 Vrms, CATII 1000 Vrms.


Based on the success of Siglent’s prior SHS portable scopes, the new -X series adds better memory depth, a faster waveform capture rate of 100,000wfm/s, timebase down to 1ns/div, enhanced triggering choices (Edge, Slope, Pulse Width, Runt, Window, Dropout, Interval, Pattern, Video), serial trigger decoding (I2C, SPI, UART, CAN, LIN), enhanced FFT precision, and waveform recording of up to 50MB internal or 2GB external. The user-friendly front panel design enables quick access to the most used scope functions. The SHS810X is the 100MHz version, and the SHS820X is the 200MHz version of non-isolated scopes, while the SHS1102X is the 100MHz version, and the SHS1202X is the 200MHz version of the fully-isolated version.


One of the significant advantages of a portable oscilloscope is its capability to make safe, floating, non-ground-referenced measurements. Inputs can safely be attached to a circuit under investigation with no regard to polarity, if the voltage and current limitations are observed. Complete isolation also reduces the risk of accidental short-circuit equipment damage.
