    At the oscilloscope bandwidth, sampling theory says the required sample rate is f = 2f . However, the theory assumes there are no frequency components above f in this case) and it requires a system with an ideal brick- wall frequency response. Agilent 1000B Series Oscilloscopes User’s Guide...

  • Page 72: Choosing The Sampling Mode

    Use the real- time sampling mode when capturing (non- repetitive) single- shot or pulse waveforms. The 1000B Series oscilloscopes provide real- time sampling rates up to 500 MSa/s (when two channels are on) or 1 GSa/s (when one channel is on).

  • Page 73: To Select The Equivalent-Time Sampling Mode

    In the equivalent- time sampling mode, the effective sample rate can be greater because the time between samples in the acquisition is shorter. Equivalent- time sampling mode requires a repetitive waveform with a stable trigger. Agilent 1000B Series Oscilloscopes User’s Guide...
  • Page 74 The benefits of the equivalent- time sampling mode are negligible when sample rates are the same as available in the real- time sampling mode. In the 1000B Series oscilloscopes, the equivalent time sampling mode can achieve up to 40 ps of horizontal resolution (equivalent to 25 GSa/s).

  • Page 110: Counter (Frequency)

    Making Measurements Counter (Frequency) The 1000B Series oscilloscopes have an integrated 6- digit hardware frequency counter. The counter operates on the currently selected trigger source and can measure frequencies from 5 Hz to the bandwidth of the oscilloscope. The counter uses the trigger comparator to count the number of cycles within a period of time (known as the gate time), so the trigger level must be set correctly.
