Access VNC : [w]
Defines the reference power in volt for LF input, available for AF signals with AC cou-
pling only. This value is used to determine the modulation depth and corresponds to
the DC power of the AF signal.
For AC coupling, the DC power component of the AF signal is not forwarded. Thus,
you must define the reference value manually.

LF In Factor
Access
: [AMPT]
Access VNC : [w]
Applies a factor to the measured power levels, e.g. to compensate certain effects in the
input system.

5.3.6 Configuring the Trace
Access : [Meas]
Access VNC : [a]
Trace settings determine how the display values are calculated from the measured val-
ues.
Trace mode ................................................................................................................. 157
Average Count ............................................................................................................ 158
Trace mode
Defines the update mode for subsequent traces.
"Clear/Write" Overwrite mode (default): the trace is overwritten by each sweep
"Average" The average is determined over several sweeps
The
Average Count determines the number of averaging procedures.
"Max Hold" The maximum value is determined over several sweeps and dis-
played. The R&S
EVSG1000 saves each trace point in the trace
memory only if the new value is greater than the previous one.
The
Average Count determines the number of sweeps to evaluate.
"RMS" The RMS value for each trace point over several sweeps is deter-
mined and displayed.
The
Average Count determines the number of sweeps to evaluate.
