ues that are constantly updated. If an instrument function
is grayed out in the menu, the purchase of an option/up-
grade voucher is required in order to unlock this feature. If
the softkey of the grayed-out function is pressed, then an
info box appears on the screen with the required option/
upgrade voucher (see Chapter 3).
6.2 Display Modes (VIEW Menu)
The R&S®HMC8015 power analyzer includes ve differ-
ent display modes for the display of measurement results;
these can be enabled by activating options/upgrade
vouchers. The display modes can be selected using the
VIEW menu. The following display modes are available:
❙ Numeric mode: (default display)
Numeric display, toggles between six and ten
measurement parameters presented as cells with four
different conguration pages; this provides a quick
overview of the individual, congurable measurement
value cells.
❙ Harmonics mode:
Bar graph of the rst 50 harmonics; this represents the
density of voltage / current as a percentage, absolute
value or as a list. HARMONICS mode is only available in
conjunction with the HOC151 option or the HVC151
upgrade voucher.
❙ Waveform mode:
Displays the waveform (for one cycle of voltage, current
or power data). WAVEFORM mode is only available in
conjunction with the HOC151 option or the HVC151
upgrade voucher.
