The 1000 Series from RIGOL include the B, D, and E series oscilloscopes. The E Series are the value leader with 50-100 MHz models that include 2 channels and 1 Million points of memory. The D Series add low speed digital capture enabling basic mixed signal analysis in a economic package. The B Series provide more speed and power including our economic 4 channel, 200 MHz DS1204B model which provides 2 GSa/sec sampling. With features including FFTs, record and replay, roll mode, alternate trigger mode, and adjustable trigger sensitivity the 1000 Series is a great entry for value oscilloscope requirements.
