<Ch> Channel number. If unspecified the numeric suffix is set to 1.
<center_frequency> Center frequency of the sweep.
Range [def. unit] Depending on the instrument model [Hz]. The increment
(parameters UP or DOWN) is 0.1 kHz.
*RST value Center of the analyzer's maximum frequency range: (f
MIN
+
f
MAX
)/2
SCPI, Command
Types Confirmed, command or query.
Example:
FUNC "XFR:POW:RAT B1, A2"
Activate a frequency sweep and select the ratio B1/A2 as
measured parameter for channel and trace no. 1.
FREQ:CENT 100MHz
Set center frequency to 100 MHz.
FREQ:SPAN 50000
Set frequency span to 50 kHz.
The measurement range defined by means of the center frequency and the current span
([SENSe<Ch>:]FREQuency:SPAN) must not exceed the allowed frequency range of the
analyzer. If necessary, the span is reduced to min (Center – f
MIN
, f
MAX
– Center).
[SENSe<Ch>:]FREQuency:CONVersion FUNDamental | HARMonic | SHARmonic
| THARmonic | MIXer
Enables the measurement of a harmonic or the fundamental signal for channel <Ch>.
Enabling a harmonics measurement also resets the measured quantity; see program example
below.
<Ch> Channel number.
FUNDamental Measurement of the fundamental signal (no frequency-converting
mode).
HARMonic Harmonics measurement. The order of the measured harmonic, the
source port, and the receive port must be selected using the
[SENSe<Ch>:]FREQuency:CONVersion:HARMonic...
commands; see example below.
SHARmonic |
THARmonic Measurement of the 2nd or 3rd harmonic with source port 1 and
receive port 2. These parameters have been introduced for
compatibilty with the ZVR. While they are active, a query returns
HARM
.
MIXer
Mixer mode. The mixer mode is configured using the
[SENSe<Ch>:]FREQuency:CONVersion:MIXer...
commands.
