overload by strong out-of-band signals is reduced to a minimum. For frequencies
between 100
Hz to 7
GHz, the signal level of the subsequent mixer is 20 dB higher so
that the maximum input level is reduced by the gain of the preamplifier. For frequencies
above 7 GHz, the gain is 30
dB.
The use of the preamplifier is recommended when measurements with a maximum
sensitivity are to be performed. If the measurement should be performed at maximum
dynamic range, the preamplifier should be switched off.
The gain of the preamplifier is automatically considered in the level display. The disad-
vantage of a poorer large-signal immunity (intermodulation) is reduced by the connec-
ted preselector.

Exported Peak List
When you export the (final) peak list, the results are saved in an ASCII file. The con-
tents of the file are split into several section.
●
The header contains general information about the measurement and instrument
settings and characteristics.
It consists of three columns, separated by a semicolon: parameter name; numeric
value; unit
●
The data section contains information about the evaluation of the data and the con-
tents of the peak list.
The data section always starts with
Trace <n> [Final]:
