[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.

Types Device-specific, command or query. Returned values:
FUND
or
HARM
.
Example:
*RST; FREQ:STAR 0.5E+9; STOP 1E+9
Reset the analyzer (activating a frequency sweep) and set the sweep
range between 1 GHz and 1.1 GHz.
FREQ:CONV:HARM:ORD 4; SPOR 1; RPOR 2
Configure a 4
th
harmonic measurement with source port 1 and receive
port 2. The measurement is still not enabled.
FREQ:CONV HARM
Enable the configured harmonic measurement.
CALC:PAR:MEAS? "TRC1"
Query the measured quantity. The analyzer measures the wave
quantity b2, the response is
'B2D1SAM'
.
FREQ:CONV:HARM:RELative ON
Enable the relative harmonic measurement, creating a new channel
and a new trace
Trc2 .
CALC2:PAR:MEAS? "TRC2"
Query the measured quantity in the new channel no. 2. The analyzer
still measures the wave quantity b2, the response is
'B2D1SAM'
.
CALC2:MATH:STAT?
Check whether the active trace in channel no. 2 (i.e. Trc2) is a
mathematical trace
:
the response is
1
.
