In frequency mode the parameters of the “MEASUREMENT OPTIONS“ menu
have no effect. All parameters have to be chosen from the virtual menu of the
main screen:
• ”MODE”: Time, FFT or Freq. log (see section 6.1).
• ”FIELD”: electric (E) or magnetic (H) field (H-field only available for WPH-DC ).
• ”SPAN”: select the frequency range available depending on the probe (affects
only the FFT):
• 40 Hz (0.1 Hz resolution)
• 400 Hz (1 Hz resolution)
• 4 kHz (10 Hz resolution)
• 40 kHz (100 Hz resolution)
• 400 kHz (1 kHz resolution)
• ”LIMIT”: allows selection of desired standard.
• None: No weighting will be applied and the measurement will be displayed
in the desired units.
• One of the limits: The measurements will be weighted in accordance with
the chosen limit and result displayed as a % of that limit (over 100% means
the limit is being exceeded).
• ”HOLD”:
• Off: no “Max Hold” applied. FFT values updated on screen every half second.
• Max: “Max Hold” applied. All values keep the maximum level detected.
This option is recommended for taking a single measurement to check
compliance with a limit: just select the desired limit, activate ‘Max Hold’,
wait the appropriate time and press Log to save the maximum peak,
RMS and FFT values. Duration of “Max Hold” function is displayed in
measurement information during measurement and in the final screen of
the saved result.
The “Max Hold” function can be reset by either a long press of the “Max
Hold” or “Reset” button in the dynamic menu.
• ”AXIS”: useful for applications where finding the source of the emission is
important.
• T: shows the FFT for the total field value.
• X: FFT of the X axis.
• Y: FFT of the Y axis.
• Z: FFT of the Z axis.
