"2F" Two frequencies are measured at the same time. Which frequencies
are measured is configured by the
Freq settings.
The numeric results are calculated as the sum of both frequencies. In
the RF Level display, the individual carriers are also indicated. In the
RF Spectrum preview, both carriers are displayed.
Remote command:
COM_1F2F_MEASMODE
on page 323
Carrier Configuration
Access : [Config]
Access VNC : [s] > "F1"
Configures the carriers and frequencies for measurements on a single or two frequen-
cies. Which settings are available depends on the
"1F/2F" on page 124.

TX1 Offset/TX2 Offset
The two carriers are defined as offsets to either side of the nominal tone frequency.
"TX1 Offset" defines the upper carrier with a positive offset to the tone frequency. "TX2
Offset" defines the lower carrier with a negative offset to the tone frequency.
Remote command:
AMFREQ_OFFSET_TX1
on page 323
AMFREQ_OFFSET_TX2
on page 323
Tone Freq.
The nominal tone frequency used to measure all results for both carriers.
Remote command:
COM_TONEFREQ_1K01K2

Channel Frequency Configuration (CH FREQ)
Access : [CH FREQ]
Access VNC : [q]
The carrier frequency determines the nominal frequency at which the measurement is
performed.

Freq
Sets the nominal frequency for the measurement. By default, this frequency is also
assumed to be the center frequency for spectrum displays, unless an offset is defined.
For measurements on two frequencies, the frequencies are defined as offsets to this
nominal frequency.
