3 Short-Range Comms & IoT Mode
3.10 Spurious Emissions Measurement
I/Q Center Freq
Specifies the I/Q Center Frequency. Sets the center frequency to use when the I/Q
input is selected, even if the I/Q input is not the input that is selected at the time the
command is sent. Note that Center Frequency in the Frequency menu on the front
panel always applies to the currently selected input.
Remote
Command
[:SENSe]:FREQuency:IQ:CENTer <freq>
[:SENSe]:FREQuency:IQ:CENTer?
Example
:FREQ:IQ:CENT 30 MHz
Notes This command is the same in all Modes, but the parameter is Measurement Global, so the value is
independent in each Mode and common across all the measurements in the Mode
Preset 0 Hz
State Saved Saved in instrument state
Min/Max –/+40.049995 MHz
Span
Sets the span of the instrument. This parameter can send up to 20 values. The
location where the span occurs in the list sent to the measurement corresponds to
the range the value is associated with.
When sending the remote command, missing values are not permitted. If you want
to change values 2 and 6, then you must send all values up to 6. Subsequent values
will remain as they were.
The query always returns 20 values.
