SMP3 BandWith Function

SMP3 BandWith Function

The SMP3 introduces a new BW (Bandwidth) function which allows a user to choose the frequency range of the measurement.

This feature configures the maximum upper frequency measured by the device. This is selectable from a list of options in the dynamic menu BW

Figure 1: BW of 1 Hz – 20 kHz was selected. All the fields below or above the selected bandwidth are attenuated.

Benefits of the new feature include:

  • Better standard compliance: Numerous standards set different frequency ranges for their measurement. An example is the railway standard, where measurement is required only up to 20 kHz. For exposure standards, IEEE C95-1 requires measurement up to 5 MHz, with the WP10M probe, a BW up to 5 MHz can be selected.  
  • Compatibility with all selective probes: The BW function is compatible with all the selective probes from Wavecontrol. The available BW options (up to 20 kHz, 40 kHz, 100 kHz, 400 kHz, 5 MHz and 10 MHz) depend on the probe used:
    • WPH-DC: up to 20 kHz, 40 kHz.
    • WP400WP400-3: up to 20 kHz, 100 kHz, 400 kHz.
    • WP10M: up to 20 kHz, 100 kHz, 400 kHz, 5 MHz, 10 MHz.
  • Improved Frequency resolution: With the new bandwidth function a minimum frequency step of 0.1 Hz can be achieved to do FFT analysis at 16.7 Hz fields required for railway application in some countries.
  • Improved noise performance and better power consumption.
