20MHz Bandwidth Handheld DSO
The GDS-122 is a reliable and handy
instrument for all test and electronic engineers. This model is designed to
carry out complicated on-site tests. The Dual-channel unit features 20MHz of
bandwidth with a sampling rate of 100MS/s along with multimeter functionality.
The color LCD display with a resolution of 320 x 240 helps you to read waveforms
easily, especially when displaying a lot of data or multiple waveforms. The
compact design with the total weight of 690g allows engineers to carry it around
easily. The protective cover of the unit is insulated and specially designed to
guarantee endurance and reliability in tough environments. The rechargeable
Li-ion battery ensures convenience for on-site testing. |
