PicoScope (USB oscilloscope) vs DAQ hardware

What each side means here

• Product line

  PicoScope 2000 Series

  USB oscilloscopes shown with the entry 2204A and the top 2-channel 2208B. PicoScope 7 is the software (separate record).

  Shown with:

  • PicoScope 2204A
  • PicoScope 2208B

• Category

  DAQ hardware

  Only one DAQ device has a full record: LabJack T7. NI CompactDAQ is a stub and is not compared. There is no generic DAQ category record.

Key differences

• They are built for different jobs. A scope samples very fast for a short time so you can see the shape of a signal: edges, glitches, ringing, the exact timing of a pulse. The T7, the DAQ device shown here, samples more slowly but reads more channels at finer resolution and streams them to the computer. Pico itself sends long-term multi-channel level logging to PicoLog and waveshape analysis to PicoScope. Evidence: Documented

  Evidence (5)

  • Pico Technology states that PicoLog 6 (sample rates up to 1 kS/s per channel) is ideal for long-term observation of general parameters such as voltage or current levels on several channels at the same time, and less suitable for waveshape or harmonic analysis, for which the PicoScope software should be used. Evidence: Documented

  • The T7 maximum stream sample rate is 100 ksamples/second in total; for multi-channel streams this applies only at resolution index 0 or 1 with all analog inputs on the +/-10 V range, and sample rate = number of channels x scan rate (for example 5 channels give at most 20 kscans/second).

• Speed vs resolution: the entry 2204A samples at up to 100 MS/s (the 2208B at 1 GS/s) with 8-bit resolution. The T7 streams up to 100 kS/s in total with 16 bits or more. That is about a thousandfold difference in speed, traded for resolution and channel count. Evidence: Inferred

  • Arithmetic on documented figures: the 2204A real-time maximum (100 MS/s, one channel) is 1,000 times the T7 total stream maximum (100 kS/s), while the T7 has 16-bit vs 8-bit resolution and 14 vs 2 analog inputs.

• Bandwidth is a scope specification: 10 MHz on the 2204A and 100 MHz on the 2208B, measured at -3 dB. It tells you roughly how fast a signal can change before the scope starts to round it off. The T7 record has no comparable figure. Evidence: Documented
