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 (influences
only the visualization of the FFT):
• 40 Hz (0.1 Hz resolution) – only applicable to the WPH-DC
• 400 Hz (1 Hz resolution)
• 4 kHz (10 Hz resolution)
• 40 kHz (100 Hz resolution)
• 400 kHz (1 kHz resolution)
• 10 kHz (25 Hz resolution) – only applicable to the WP10M
• 100 kHz (250 Hz resolution) – only applicable to the WP10M
• 1 MHz (2.5 kHz resolution) – only applicable to the WP10M
• 10 MHz (25 kHz resolution) – only applicable to the WP10M
• 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). Limits can be filtered, see section 8.3.6.
• 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.
