Note: The LEDs on the front panel are only “on“ (light) if the measurement is
active.
Note: RF User Correction
In addition to the static external input attenuation setting, the CMU
provides a systematic correction of the measured RF power by means
of user-defined, frequency and level-dependent correction tables; see
section RF User Correction in Chapter 1.

Pow. Meter
Wideband
The Pow. Meter Wideband softkey controls the wideband power measurement and
indicates its status (RUN | HLT | OFF). The status can be changed after softkey
selection (pressing once) by means of the ON/OFF key or the CONT/HALT key.
The measurement result is in units of dBm. The analog bar to the right of the soft-
key shows the measured power relative to the total measurement range (see
Chapter 6).
The wideband power measurement is performed at the RF Frontend of the CMU
and yields the peak power of the input signal inside a wide frequency range. For
modulated RF signals, the result of the wideband power measurement depends on
the modulation characteristics. The main purpose of the wideband power meas-
urement is to indicate whether an input signal is available and whether it is advis-
able to change the Max Level settings.
Note: The RF function group provides a wide selection of power measure-
ments. For an overview see section Analyzer/Generator on p. 4.33 ff.

Reference Frequency (Connection Control – Synch.)
The tab Synch. determines the reference signals for synchronization. This includes
The internal or external Reference Frequency
The output mode for the network-specific system clock (REF OUT 2).
